Rad-D Portable Radiation MonitorFULLY TRANSPORTABLE WITH THE EXCLUSIVE LAURUS SYSTEMS PRM BRACKET MOUNTING SYSTEM!SNM DETECTOR FOR CONTAINER AND CONVEYOR BELT PACKAGE INSPECTIONThe R ad-D is a fixed-position radiation detector that is usedto monitor doorways, driveways, or loading docks. It can inspect pack-ages or luggage on conveyor belts; and it canbe integrated with an X-ray machine or a metal detector to increase the kinds of dangers detected. The rad-D can alsobe easily connected to an existing security system – to add radiation to the other types of alarms. The rad-D is small. It can be attached to walls, light poles, convey-or belts, or X-ray machines. And because it is small, it doesn’t affect the how of vehicles or pedestrians under inspection. Other, similar devices need large, fixed areas and concrete footings to mount their systems and require traffic (vehicles or people) to be forced through a fixed inspection corridor. A rad-D system can include up to four detectors – operating simultaneously, each up to 150’ away from the display electronics. The rad-Dis designed to integrate into existing security networks, using either a serial communications link or a Bluetooth wirelesslink that can communicate with a PC up to 300 feet away.With four detectors, an operator can monitor four different doorways (or driveways, or conveyor belts, etc.) anywhere in your facility. When the rad-D alarms, it can trigger active responses such as blockades or halting conveyor belts.There are two different types of rad-D detectors available: Gamma, or Neutron. The standard radiation detector searches for gamma and X-ray radiation and can beconfigured as either omni-directional or uni-directional to ensure that the unit is triggered only by what is directly infront of it, not by what is in the next traffic uni-directional to ensure that the unit is triggered only by what is directly in front of it, not by what is in the next traffic lane orFlexibility, functionality, and affordability make theRad-D a practical solution for use in:•Pedestrian Monitoring•Shipping and receiving points/conveyer operations •Security check-points•Border controls and check-points•Materials Screeningon a parallel conveyor belt. The other type, a neutron detector, is an important tool to detect the transport of illicit nuclear weapons. Many users configure a standard radiation detector and a neutron detector to cover the full spectrum of radiation. Like the mini rad-D, the rad-D is designed to be extremely easy to use and understand. It provides the operator with an easy-to-interpret single digit read out of a “1” to a “9” to show the strength of the detected radiation. The rad-D also shows the actual count of photons or neutrons. It automatically calibrates itself to the natural background radiation environment to maximize its detection sensitivity.A D V A N C E D T E C H N O L O G Y F O R A S A F E R W O R L DLAURUS Systems, Inc. - Ph: 410-465-5558 - Fax: 410-465-5257 - SPECIFICATIONSFunction Gamma Gamma/Neutron detectionDetector Gamma: 2” X 3” (51 x 76 mm) NaI; doped with ThalliumNeutron: 253 Cylindrical He3Energy Range 40 keV to 3000 keV (gamma)SensitivityWill detect 1.0 uCi of Cs137 at 1.5 meters from the face of the detectorPower Regular 120VACResponse Time < 1 secondDisplay“1” through “9” LED readout Counts Per Second (gamma)Notification Audio/LED – 3 µR/h (.03 uS/h) above background Audible Alarm92+ dBA at 24 inches (61 cm)Calibration AutomaticCalibration Biasing 16-position switch; allows manual setting for operation inhigh-radiation environments VersionsShielded version available for use with X-Ray scanning machinesSize Detector: 5" Dia, 17.5" length (13 x 45 cm)Control Unit: 6.75" x 4.2" x 3" (17 x 11 x 8 cm)Weight Detector: 27.5 lb (12,5 kg)Control Unit: 1.5 lb (.7 kg)Environment -10O F - 122 O F (-23O - 50O C)FEATURES• 24/7 Operation• No maintenance required • Easy to use – no special training • High sensitivity •Automatic background compensation to minimize false alarms•Fast detection - < 1 second to complete package inspection on a conveyor belt system •Transportable with LAURUS Systems universal mounting bracket•Available with lead shielding for use with x-Ray machine conveyor beltsRad-DLAURUS Systems, Inc. - Ph: 410-465-5558 - Fax: 410-465-5257 - 。
应用说明www.vaisala.c nVaiNet AP10 网络接入点成熟的无线环境监测技术维萨拉 viewLinc 监测系统利用基于射频技术的维萨拉 VaiNet 无线设备对环境条件进行无线跟踪。
通过线性调频扩频 (CSS)* 信号调制，VaiNet 提供稳定的通信，在长距离范围内以及严酷、复杂和闭塞的条件下依旧可靠。
长距离无线通信避免了使用中继器来提高信号强度。
VaiNet 的无线数据记录仪以及接入点已经进行了预编程，以便于可以相互定位并建立通信。
更少的设备和配置让安装更加简单，因此，即使是之前缺乏或者没有设置联网监测系统经验的用户也能部署它。
VaiNet RFL100 无线电频率数据记录仪维萨拉 VaiNet 无线技术使用 sub-GHz 频率在环境监测应用中实现更好的信号传播。
大多数配备无线设备的工业监测系统都采用某种冗余方式防止数据记录仪网络中出现单点故障。
VaiNet 通过在多个网络接入点之间分配信号负载形成冗余。
接入点和数据记录仪之间的无线信号强度决定了最佳数据传输路径。
接入点利用以太网供电 (PoE)，从而减少布线，并且可以轻松连接到 UPS*。
如果没有 PoE，则安装时提供单独的电源。
此外，大多数RFL100 型号都是完全无线的，由电池供电，可确保系统在停电期间继续监测。
如果无线网络掉线，每个记录仪可以保留长达 30 天的数据，并且，如果以太网局域网出现故障，接入点将进行额外的数据存储。
一旦网络恢复，数据记录仪和接入点就会自动将历史数据回填到监测系统软件，以确保历史记录不间断。
由于其他频率已得到广泛使用，sub-GHz 无线技术有很多优点。
VaiNet 在繁重的 2.4 GHz 频段外部进行通信，信号不易受到干扰。
sub-GHz 无线通信的另一个优点是低频信号，这意味着信号传播距离更长，穿透力更好。
工业环境和仓库环境中典型的障碍（水泥砌块墙、金属货架、重型设备、液体产品、铝箔包装）更容易被低频信号穿透。

www.vaisala.cn客户案例Aidian Oy 是一家国际性的诊断检测公司，在开发和研制针对医院和保健中心中的基本医疗保健需求的诊断检测方面，拥有 50 年的经验。
它的产品包括血液检测套件（例如，用于快速测定炎症水平）、微生物快速检测产品、Dipslides，以及用于监测各类机构卫生水平的检测产品。
Aidian 的前身是 Orion Diagnostica，于 2018 年 5 月被北欧私募股权公司Axcel Management A/S 收购，并于次年更名为 Aidian Oy。
除了在艾斯堡的总部外，Aidian 在瑞典、挪威、丹麦、德国、捷克共和国、斯洛伐克、匈牙利、波兰和中国都设有当地办事处。
新收购，新监测系统“当我们脱离 Orion 时，我们不得不更换监测系统，因为旧系统的许可证归Orion 所有。
该系统的硬件陈旧，且没©Aidian Oy用于诊断的原材料和产品具有特定的存储温度。
Aidian 的生产设施中分布着许多不同的冷冻库和冷藏室，如今它们可以通过维萨拉 viewLinc 监测系统得到全天候监测。
有备件可用，因此无论如何都有必要进行更新。
”Aidian 的开发工程师 Patrik Hellström 解释说。
他所在的团队负责投资、验证和系统更新等事项。
Hellström 从 Orion 加入 Aidian，因此对于之前的监测系统，他有着丰富的经验。
按照 Hellström 的说法，Aidian 的新监测系统的两个候选供应商是 Orion Diagnostica 的旧系统的生产商和维萨拉。
选择维萨拉，是因为维萨拉是可靠的传感器制造商。
他说道：“viewLinc 系统的多功能温度、湿度和工艺测量以及与之相关的外部指示器是主要的决定因素，这是我们的主要标准之一。
”由于存在停止使用旧系统的最后期限，因此新系统的部署时间很紧。
此外，还必须在两个系统并行运行一段时间的情况下进行监测，以确保一切运行正常。

The background luminance has an effect on the distance from which the pilot can see the runway lights.Resembles Human EyeLM21 is a precision photometer with a verified photopic spectral response. It measures the total amount of light coming in from an angle of 6 degrees,and converts the measured data to cd/m 2. The sensor sends themeasurement data to the interface unit of a Vaisala transmissometer or forward scatter visibility sensor. The interface unit combines both the visibility and background luminance data into the same message and sends it to the main RVR computer.LM21 can be connected to Vaisala Transmitter LT31 and Vaisala Forward Scatter Sensor FS11. LT31 and FS11 are connected using a RS-485 serial line.Comprehensive Self-DiagnosticsLM21 is an intelligent, standalone sensor.To ensure reliable and uninterrupted operation, it has extensive self-monitoring functions with high power heating features. The sensor measures and compensates for the attenuation effect of window contamination. It ensures that measurement accuracy is maintained between window cleanings,and also extends the cleaning interval.The optical path clearance monitoring circuitry verifies that measurement is not affected by obstructions.Easy to CalibrateThe calibration of LM21 is traceable to international measurement standards for luminous intensity. Vaisala Field Calibrator LMA21 is a unique field calibration device that is available for quick field calibration. It provides a stabilized and diffused white light beam for LM21 calibration.The calibration coefficients for light intensity have been defined during factory calibration and stored inthe LMA21 memory. Calibration starts automatically when LMA21 is connected to LM21. LM21 reads the calibrationcoefficients from the LMA21 memory and performs the calibration. The status and result of the calibration is displayed with5 LED indicators on the cover of LMA21.LM21 measures the ambient light level or background luminance in RVR applications.

a r X i v :a s t r o -p h /0402053v 1 2 F eb 2004Monitoring and Discovering X-ray Pulsars in the SmallMagellanic CloudR.H.D.Corbet ∗†,ycock ∗∗‡,M.J.Coe ∗∗,F.E.Marshall ∗and C.B.Markwardt ∗§∗Laboratory for High Energy Astrophysics,Code 662,NASA Goddard Space Flight Center,Greenbelt,MD 20771†Universities Space Research Association∗∗School of Physics and Astronomy,Southampton University,SO171BJ,United Kingdom‡Current address:Harvard-Smithsonian Center for Astrophysics§University of MarylandAbstract.Regular monitoring of the SMC with RXTE has revealed a huge number of X-ray pulsars.Together with discoveries from other satellites at least 45SMC pulsars are now known.One of these sources,a pulsar with a period of approximately 7.8seconds,was first detected in early 2002and since discovery it has been found to be in outburst nine times.The outburst pattern clearly shows a period of 45.1±0.4d which is thought to be the orbital period of this system.Candidate outburst periods have also been obtained for nine other pulsars and continued monitoring will enable us to confirm these.This large number of pulsars,all located at approximately the same distance,enables a wealth of comparative studies.In addition,the large number of pulsars found (which vastly exceeds the number expected simply by scaling the relative mass of the SMC and the Galaxy)reveals the recent star formation history of the SMC which has been influenced by encounters with both the LMC and the Galaxy.THE EARLY HISTORY OF SMC X-RAYPULSARSThe first known X-ray pulsar in the SMC was the per-sistent supergiant system SMC X-1.Two luminous tran-sients (SMC X-2,SMC X-3)were discovered with SAS-3.[1].These were thought to be transient Be/neutron star systems although pulsations were not detected due to the low sensitivity of SAS-3.It was hypothesized that SMC pulsars were exceptionally luminous,possibly related to the low metallicity of the SMC.[2]This was later to be disproved and an alternative explanation found for the high luminosity of the first few SMC X-ray pulsars to be discovered.Over the years a few pulsars were also found with satellites such as ROSAT.[3]SMC X-RAY PULSARS WITH RXTESerendipitous RXTE slew observations in 1997showed a possible outburst from the vicinity of SMC X-3.Fol-low up target of opportunity pointed RXTE observa-tion showed a complicated power spectrum with sev-eral peaks that were not all harmonically related to each other.Imaging ASCA observations were next made which showed two separate pulsars,however neither wasfound to be located at the position of SMC X-3.A more detailed look at RXTE power spectrum showed that in fact three pulsars were simultaneously active [4].These observations were the first sign of the existence of a very large SMC X-ray pulsar population.THE RXTE MONITORING PROGRAMRXTE has been regularly monitoring the SMC since 1997.We have discovered very many transient X-ray pulsars.For those sources where optical counterparts have been identified they are all found to be Be stars.We primarily make weekly observations of one particu-larly active region near SMC X-3.Other SMC regions have been monitored monthly depending on the amount of time awarded in a particular observing cycle.We use power spectrum to extract pulsed flux from any pulsars.In this way,although the PCA is not an imaging in-strument,the pulsed flux from multiple sources can be monitored independently.When new sources are identi-fied we use cross scans in Right Ascension and declina-tion to localize the position of the new sources.Initially scans were done as Target of Opportunity observations.However,this was not always successful if the target had faded before the TOO could be performed.Therefore wecurrently include R.A./dec.scans in all our SMC obser-vations.For new sources we thus obtain at least minimal positional information.However,position determination can be problematic if too many pulsars are simultane-ously active.A log of known X-ray pulsars in the SMC is currently maintained at http://http://lheawww. /~corbet/pulsars/.ORBITAL PERIODSTen pulsars have candidate orbital periods determined by us from long term periodicities in their pulsedflux[5]. The statistical significance of the orbital period determi-nations varies depending on,for example,the number of outbursts detected and whether the outbursts are“type I”or“type II”(i.e.related to periastron passage or not).In addition,optical monitoring of optical counterparts,has also revealed the orbital periods of several systems[6] [7].For those sources where only a small number of out-bursts have been seen so far continued monitoring should conclusively pin down the orbital periods.For two SMC X-ray pulsars we have very solid orbital periods deter-mined from fairly recent observations.For the7.78s pul-sar(recently determined to be SMC X-3[8])we observed 9outbursts in2002and early2003.All of these outbursts are consistent with P orb=45.1±0.4days.More recently, a set offive outbursts from the144s pulsar in2003and 2004have revealed an orbital period of61.4±1.1days. The orbital periods derived so far appear to follow the correlation between orbital period and spin period found for Galactic Be star systems(see e.g.Corbet1986[9]). WHY ARE THERE SO MANY PULSARSIN THE SMC?A simple scaling based on the relative masses of the SMC and Galaxy predicts only∼2SMC X-ray pulsars.How-ever about45are now known and are listed in the ta-ble.A more realistic prediction of the expected number of X-ray pulsars in the SMC should come from the star formation rate as high-mass X-ray binaries have rather short lifetimes.However,estimates of the current star formation rate in the SMC do not give very large num-bers.Estimates of the SMC star formation rate from in-tegrated colors[10]and from Hα[11]give0.064and 0.046M⊙/yr respectively compared to the Galactic star formation rate of a few M⊙/yr.However,SMC has ex-perienced encounters with LMC and Galaxy in past and these encounters likely triggered bursts of star formation (see e.g.Yoshizawa&Noguchi2003[12]).The remnants of this star formation burst may now seen as high mass Be star X-ray binaries.THE POTENTIAL OF THE SMCPULSAR DATABASEAll the SMC pulsars lie at approximately same distance (although the SMC does have a substantial depth).This facilitates comparative studies(e.g.pulse profiles)as function of luminosity.We are continuing to build up a huge X-ray pulsar database with RXTE which can be used to study pulsar parameters in may different ways. For example,we can now start to compare the pulse pe-riod distributions and the pulse/orbital diagrams for the SMC and the Galaxy.One notable difference so far be-tween the SMC and the Galaxy is the apparent lack of supergiant wind accretion systems in the SMC.In the Galaxy these sources have luminosities of a few1036 to1037ergs/s and,unless the SMC’s lower metallicity causes such systems to have very much lower luminosi-ties,should be detectable in our observations which have limiting luminosities of roughly1036ergs/s.Although our weekly monitoring observations have durations of about7000s,which makes them somewhat less sensi-tive to the longer pulse periods exhibited by wind accre-tion systems,we have had some longer duration observa-tions and long Chandra and XMM observations should also have been sensitive to detection of this type of sys-tem.The overall pulsar properties of the SMC can tell us about the relative evolution of a very nearby galaxy and we can compare source count properties with predictions of various models.SMC PULSAR MONITORING BEYONDRXTEAlthough Chandra and XMM are sensitive to source de-tection,neither is well suited to frequent monitoring to determine orbital periods.The RXTE ASM is just sensi-tive enough to detect the brightest(1038ergs/s)outbursts from reasonably isolated SMC sources such as SMC X-2[13].One more sensitive ASM that may have potential for the long term study of the SMC pulsars is the Lob-ster All Sky Monitor that will be installed onboard the International Space Station.[14]This instrument should be very sensitive but source count rates will be low.Ad-ditionally,lobster-type instruments are not sensitive to harder X-rays.The ideal type of instrument with which to conduct long term SMC X-ray pulsar studies may well be an imaging instrument of several degrees FOV such as on the proposed MIRAX mission[15],continuously staring at SMC.TABLE1.X-ray Pulsars in the SMC0.716 3.9SMC X-12.165XTE J0119-7312.374SMC X-22.7632RX J0059.2-71383.34AX J0105-7224.782XTE J0052-7236.8487.7845.4XTE J0055-725=SMC X-38.028.882E0050.1-72479.13AX J0049-73215.3RX J0052.1-731916.618.3622.07RX J0117.6-733031.0XTE J0111.2-731734.0846.4Poor position,not same as46.6s source?46.6139XTE,1WGA J0053.8-722651Same as25.5s58.97123XTE J0055-72474.7AX J0049-72982.48991.188.25AX J0051-72295.2101.4AX J0057.4-7325138.0125Optical period140.1XMMU J005605.2-72220014461152.1164.7169.3XTE J0054-720172.4202XMMU J005920.8-722316263.6XMMU J004723.7-731226280.4304.49323RX J0050.8-7316 348/343rapid spin down455+-2RX J0101.3-7211503.5564.83701755.5394RX J0049.7-7323FIGURE1.Examples of one recent month of RXTE ob-servations of the SMC.A power spectrum is shown for each weekly observation in this month and pulsar detections are marked.REFERENCES1.Clark,G.,Doxsey,R.,Li,F.,Jernigan,G.,and vanParadijs,J.,ApJ,221,L37(1978).2.Westerlund,B.,A&ARv,2,29(1990).3.Hughes,J.,ApJ,427,L25(1994).4.Corbet,R.,Marshall,F.,Lochner,J.,Ozaki,M.,and Ueda,Y.,IAUC,220(1998).ycock,S.,Corbet,R.,Coe,M.,Marshall,F.,Markwardt,C.,and Lochner,J.,ApJ(2004).6.Cowley,A.,and Schmidtke,P.,AJ,126,2949(2003).7.Edge,W.,Coe,M.,and McBride,V.,ATEL,220(2004).8.Edge,W.,Coe,M.,Corbet,R.,Markwardt,C.,andLaycock,S.,ATEL,225(2004).9.Corbet,R.,MNRAS,220,1047(1986).10.Rocca-V olmerange,R.,Lequeux,J.,and Maucherat-Joubert,M.,A&A,104,177(1981).11.Kennicutt,R.,Tamblyn,P.,and Congdon,C.,ApJ,435,22(1994).12.Yoshizawa,A.,and Noguchi,M.,MNRAS,339,1135(2003).13.Corbet,R.,Marshall,F.,Coe,M.,Laycock,S.,andHandler,G.,ApJ,548,L41(2001).14.Fraser,G.,Brunton,A.,Bannister,N.,Pearson,J.,Ward,M.,Stevenson,T.,Watson,D.,Warwick,R.,Whitehead, S.,and O’Brien,P.,SPIE,4497,115(2002).15.Staubert,R.,Rothscild,R.,Heindl,W.,Matteson,J.,0246810−10−5510157.78s Pulsar − Orbital Period DeterminationFlare Cycle NumberObservedFlareTime−Calculated(Days)FIGURE2.Determination of the orbital period of the7.78s pulsar recently identified as SMC X-3.[8]Wilms,J.,Kendziorra,E.,Remillard,R.,Braga,J.,andHeise,J.,SPIE,4851,365(2003).10010110210310−1100101102103104BBB B B B BB B B B B B B B B B B B B B (B)b bb b b b bOrbital Period (days)W W W W W W WW W R RRW/RP u l s e P e r i o d (s e c o n d s )W?FIGURE 3.Orbital and spin periods of high-mass X-raybinaries.“R”=Roche-lobe overflow mass transfer,“W”=wind accretion system,“B”=Galactic Be star source,“b”=SMC Be star source,“(B)”=LMC Be starsource.FIGURE 4.A comparison of the pulse period distributions of the SMC,Galaxy,and the LMC [5].Note that that distributions are not normalized but show absolute numbers of pulsars.The SMC distribution does not contain several recently discovered X-ray pulsars.。
