摘要
研制了一种新的2×4双层结构多气隙电阻板室探测器(MRPC),宇宙线测试结果表明,2×4双层结构MRPC有较低的工作电压和较长的工作坪区,探测效率90%以上,时间分辨可以达到100ps.
A new type of multi gap resistive plate chamber （MRPC） with a structure of 2×4-gap were tested by cosmic-rays. The results show that 2 × 4-gap MRPCs have a lower working voltage, a longer voltage plateau, a higher efficiency and a better time resolution than traditional 6-gap MRPCs. The results show that detecting efficiency could be higher than 90% and that time resolution is about 100 ps.
