¹⁷F+p共振态弹性散射实验中PPAC性能测试

摘要: 在兰州放射性次级束流线（RIBLL）上进行的¹⁷F+p共振态弹性散射实验中，用到的位置灵敏平行板雪崩探测器（PPAC）使用延迟线读出法，使得PPAC有着很干净的本底噪声和较好的信噪比。对实验所用的PPAC进行了性能测试，经分析，位置分辨好于1 mm、时间分辨为0.29 ns、探测效率为97%以上，达到了实验要求。

Abstract: A parallel plate avalanche counter (PPAC) with delay-line readout was designed to be used in the experiment of investigation of resonant properties in ¹⁸Ne via ¹⁷F+p. The position resolution, time resolution, and detection efficiencies of PPAC were researched in detail. The results of analysis show that 1 mm position resolution, 0.29 ns time resolution, and 97% detection efficiencies are achieved.
