论文摘要
近年来，气体电子乘数已被证明是可靠的放大阶段，并可以在及时投影室中使用。我们的小组开发了1 dm $^3 $ Active Volume Double Doble TPC，空间分辨率为50 $μm$，280美元$ $ m。定制设计的FPGA数据采集系统可实现大约100 kHz $ \ cdot $ mm $ $^{ - 2} $的费率功能，提供出色的逐步轨道位置和角度信息，分别大于0.1 mm和1 mrad。系统的广泛动态范围可实现从$^{4} $的标识，他使用电离测量值最高$^{86} $ kr。这些TPC中的两个计划以串联模式运行，以滤波停机粒子并实现上的角度分辨率。
In recent years Gas Electron Multipliers have proven to be reliable amplification stages at high beam rates, and can be used also in Time Projection Chambers. Our group developed a 1 dm$^3$ active volume double-GEM TPC, with spatial resolution of 50 $μm$ and 280 $μ$m. Custom designed FPGA data acquisition system enables rate capability for about 100 kHz$\cdot$mm$^{-2}$, providing excellent track-by-track position and angular information, better than 0.1 mm and 1 mrad respectively. The wide dynamic range of the system enables identification from $^{4}$He up to $^{86}$Kr using ionization measurement. Two of these TPCs are planned to operate in tandem mode to filter off-time particles and to achieve a superior angular resolution.
