用于未来对撞机实验的快速定时微模式气体探测器的性能

Performance of a fast timing micro-pattern gaseous detector for future collider experiments

Antonello Pellecchia, Piet Verwilligen

摘要:

快速定时MPGD是一种微模式气体探测器,旨在实现亚纳秒的时间分辨率,同时保持在高速率环境中大面积仪器的能力;这种技术的应用前景在未来的对撞机和医疗诊断的高能物理实验与飞行时间的方法。这项工作表明,进行了系统的研究FTM原型的性能的GEM箔涂有电阻DLC膜,其发展是必不可少的FTM操作。电阻箔的性能已经测试了几种气体的混合物,并与导电箔上获得的结果进行了比较。结果表明,FTM的性能目前受到DLC涂覆的GEM箔的制造技术的限制,仅在基于异丁烷的混合物中可获得高增益。

英文摘要:

The fast timing MPGD is a micro-pattern gaseous detector conceived for achieving sub-nanosecond time resolution while maintaining the ability to instrument large areas in high-rate environments; applications of such technology are perspected in high-energy physics experiments at future colliders and medical diagnostics with time-of-flight methods. This work shows the systematic studies carried on an FTM prototype on the performance of GEM foils coated with resistive DLC films, whose development is essential for the FTM operation. The resistive foil performance has been tested with several gas mixtures and compared with the results obtained on conductive foils. The results show that the performance of the FTM is presently limited by the technology of manufacturing of DLC-coated GEM foils, with high gains reachable exclusively in isobuthane-based mixtures.
