论文摘要
混合读数时间投影室(TPC)具有同时的光学和电荷读数。光学读数在活动体积中提供了粒子轨道的2D图像,而电荷读数则提供了有关垂直于图像平面的粒子位置的其他信息。在高压下工作的混合读数TPC是物理案例的有吸引力的设备,在这种情况下,需要出色的空间分辨率和高目标密度,例如测量长基线中微子振荡实验源的中微子束。在本文中,我们提出了两种不同的工作,以开发混合TPC技术的目标:a)使用光学和电荷读数的气体电子乘数进行委托。 b)基于Garfield ++仿真的多线比例室的气体增益的分析参数化,该模拟在用测量验证时允许将来跳过这些模拟。
A hybrid readout Time Projection Chamber (TPC) has a simultaneous optical- and charge readout. The optical readout provides 2D images of particle tracks in the active volume, whilst the charge readout provides additional information on the particle position perpendicular to the image plane. A hybrid readout TPC working at high pressure is an attractive device for physics cases where an excellent space point resolution and a high target density is required as e.g. measuring a neutrino beam at the source of a long baseline neutrino oscillation experiment. In this paper we present two different lines of work towards the goal of developing hybrid TPC technology: a) Commissioning of a set-up with gas electron multipliers employing optical and charge readout. b) An analytical parametrisation of the gas gain for a multi wire proportional chamber based on garfield++ simulations, which - when validated with measurements - allows to skip these simulations in the future altogether.
