摘要
采用直径为25 μm的不锈钢阳极线的单线位置敏感计数器，在自猝灭流光(SQS)模式下实现了位置传感。采用标准NIM电子电路和新型比数转换器(RDC)，在100 mm长和1.82 m长计数器上获得了4.5 keV x射线的总位置分辨率分别为0.26 mm和0.69 mm fwhm。讨论了SQS模式在位置传感中的应用问题。
Charge-division type position sensing with a single-wire position sensitive counter in the self-quenching streamer mode
Using single-wire position sensitive counters with a stainless-steel anode wire of 25 μm diameter, position sensing has been performed in the self-quenching streamer (SQS) mode. Overall position resolutions of 0.26 mm and 0.69 mm fwhm for 4.5 keV X-rays were obtained for 100 mm long and 1.82 m long counters, respectively, by means of standard NIM electronic circuits and a new ratio-to-digital converter (RDC). Problems in the application of SQS mode to position sensing are discussed.
