摘要:

我们研制了一个用于高能重离子碰撞实验的气体电子倍增器(GEM-TPC)时间投影室。为了研究其性能,我们进行了3种气体(Ar(90%)-CH 4(10%),Ar(70%)-C2 H6(30%)和CF 4)的束流测试。探测效率为99%,空间分辨率为79 $μ$ m的焊盘-行方向和313 $μ$ m的漂移方向。测试结果表明,GEM-TPC满足高能重离子碰撞实验的要求。介绍了GEM-TPC的结构和性能。

英文摘要:

We developed a prototype time projection chamber using gas electron multipliers (GEM-TPC) for high energy heavy ion collision experiments. To investigate its performance, we conducted a beam test with 3 kinds of gases (Ar(90%)-CH4(10%), Ar(70%)-C2H6(30%) and CF4). Detection efficiency of 99%, and spatial resolution of 79 $μ$m in the pad-row direction and 313 $μ$m in the drift direction were achieved. The test results show that the GEM-TPC meets the requirements for high energy heavy ion collision experiments. The configuration and performance of the GEM-TPC are described.
