【摘要】 介绍了对自行研制的低气压多丝正比室在低能下的系统测试结果。结果显示:在最佳工作条件下,低气压多丝正比室的位置分辨率小于 0.8 mm,时间分辨率小于2 ns,低能下的探测效率接近 100％,适合于放射性核束的束流监测。更多还原

【Abstract】 The systematic tests of a low pressure multi--wire proportional chamber deve-loped by ourself at low energy were performed. lt is shown that at the best work condi-tion the position resolution is better than 0. 8 mm, the time resolution is better than2 ns, and the detecting efficiency is nearly 100% at the low energy, so it is fit for theinvestigation of the radioactive ion beam.更多还原
