【摘要】 本文研究了充Ne的平行板火花室在气压200—700毫米汞柱范围内探测效率与气压、间隙宽度和工作电压的关系;也研究了在此气压范围内火花室阈值电压与气压和间隙宽度的关系。实验表明:火花室的效率随气压P与间隙d乘积的增加和工作电压的增大而增加,火花室的阈值电压服从Paschen规律。更多还原

【Abstract】 The dependence of parallel plate spark chamber efficiency on pressure, gap widths and applied voltage has been studied in the pressure range 200—700 mm Hg of neon. The dependence of the threshold voltage on pressure, gap widths has also been studied in the same range. It is shown that the efficiency increases when the product of pressure P and gap with d and voltage increase, and the threshold voltage of the spark chamber follows Paschen’s Law.更多还原
