M1111型β探測(cè)器

The M1111 β detector

M1111型β探測(cè)器能夠測(cè)量低能β射線，因其優(yōu)異的抗力，能夠廣泛用于環(huán)境檢測(cè)、精密測(cè)量、科研等領(lǐng)域。本公司研發(fā)的M1111型β探測(cè)器主要由端窗光電倍增管、高壓電源模塊、信號(hào)成形電路、閃爍體等組成。

本產(chǎn)品具有簡(jiǎn)單方便、可靠性高及探測(cè)效率高等優(yōu)點(diǎn)。在出廠前，已經(jīng)過各項(xiàng)性能測(cè)試，接通電源，將輸出端與計(jì)數(shù)單元連接即可使用。

M1111 β detector can measure low energy β ray, because of its excellent anti-interference ability, can be widely used in environmental detection, precision measurement, scientific research and other fields. The M1111 β detector is mainly composed of photomultiplier, high voltage power supply module, signal forming circuit and scintillator . 

The product has the advantages of simplicity, high reliability and high detection efficiency.  Before leaving the factory, it has been tested in all aspects, connected to the power supply, the output end can be used with the counting unit.

技術(shù)參數(shù)

（測(cè)試環(huán)境溫度25℃）

注：

1) 使用60μCi的¹⁴C源測(cè)試，源距離探測(cè)器3mm。

2) 1小時(shí)不穩(wěn)定性測(cè)試過程：探測(cè)器采集的計(jì)數(shù)率在10.0±0.5ks-1，設(shè)置每個(gè)數(shù)據(jù)采集時(shí)間為4min，每組數(shù)據(jù)累積采集15個(gè)數(shù)據(jù)（1小時(shí)），計(jì)算每組數(shù)據(jù)的各個(gè)值與均值的偏差的值，連續(xù)測(cè)試3組（3小時(shí)），取3組中的值為1小時(shí)工作不穩(wěn)定性測(cè)試值。
