资料介绍

介绍了用于便携式核辐射测量仪表中为CM计数管提供高压的高压电路。由各功能模块组成闭环控制的高压电路,通过反馈随时调整电压,降低干扰,提高稳定性。测试结果显示电路工作时,探测器的电压很快达到预期值,数值稳定,纹波系数小,使研究测量仪表的可靠性及可用性大大提高。该高压电路已成功运用于便携式γ剂量率仪表中,在相关核辐射测量仪表电路设计中有一定应用价值。

The GM counter high voltage circuit is introduced, this circuit usually used in portable nuclear radiation measuring instrument. The high voltage circuit through each function module forms closed -loop control, which controls feedback adjust voltage, reduces the interference, improves the stability. The test results show that the circuit can work normally, the detector voltage quickly reaches the expected value, the numerical stability, small ripple coefficient, makes the reliability of the measuring instrument and availability is greatly increased. The high voltage circuit has been successfully used in portable gamma dose rate meter, in the related nuclear radiation measurement circuit design has certain application value.
