Abstract

Systematic test on each detect unit of parallel plate avalanche counter (PPAC) used in the fission multi-parameter measurement was performed with a ²⁴¹Am α source to get the time resolution and position resolution. The detectors work at 600 Pa flowing isobutane and with -600 V on cathode. The time resolution was got by TOF method and the position resolution was got by delay line method. The time resolution of detect units is better than 400 ps, and the position resolution is 6 mm. The results show that the demand of measurement is fully covered.
- parallel plate avalanche counter,
- time resolution,
- position resolution
