Product Description

 

 

 

 

主要技术指标

 

 

 

 

仪器对于90Sr-90γ源的2πβ探测效率比≥60%,对于239Pu源的2πα效率比≥90%;

β本底≤0.1cm-2min-1,α本底≤0.002cm-2min-1;

α/β交叉性能:α→β<2%;

β→α<0.3%;

灵敏度:α=5×10-4Bq, β=0.5×10-3Bq;

长期稳定性

效率稳定性:一起连续通电24小时,探测器效率变化α小于<3%,β<5%;

本底在32小时的测量时间内,本底技术变化符合统计规律,

本底稳定性:在24小时的测量时间内,本底计数变化应在(Nb±3o)的范围内,其中Nb为本底计数的平均值,o为本地计数的标准误差。

Product features
 
Program controlled high voltage technology: the alpha threshold, beta low threshold (beta L), beta high threshold (beta H) and high pressure of detectors can be adjusted by computer.
High automation: the computer automatically controls the whole process of measurement, automatic data processing, and can print results and original data lead room structure novel; the innovative lead room structure design makes all the distance between the detector and the main detector small, the inverse efficiency is higher, the bottom is lower.
Innovative design of integral cabinet: making measurement system difficult to integrate, occupy less space and operate more conveniently.
Special industrial computer is adopted to ensure that the system runs steadily and reliably for a long time.
Long term stability and reproducibility of the instrument
