TORCH 是一种创新的高精度飞行时间系统，可在高达 10 GeV/c 的困难中间动量区域中提供粒子识别。也适合大面积应用。该探测器通过对 1 厘米厚的石英辐射器中发射的切伦科夫光子的成像来提供飞行时间测量。光子通过全内反射传播到石英板的边缘，然后聚焦到外围的光子探测器阵列上。每个入射带电粒子需要实现约 10-15 ps 的飞行时间分辨率，以便距离相互作用点 9.5 m 的 TORCH 能够实现高达 10 GeV/c 动量的 3 sigma kaon-pion 分离。假设每个入射带电粒子检测到约 30 个光子，这需要将单个光子的到达时间测量到大约 70 ps。本文将描述 TORCH 原型的设计，其中涉及许多突破性且具有挑战性的技术。
TORCH is an innovative high-precision time-of-flight system to provide particle identification in the difficult intermediate momentum region up to 10 GeV/c. It is also suitable for large-area applications. The detector provides a time-of-flight measurement from the imaging of Cherenkov photons emitted in a 1 cm thick quartz radiator. The photons propagate by total internal reflection to the edge of the quartz plate and are then focused onto an array of photon detectors at the periphery. A time-of-flight resolution of about 10–15 ps per incident charged particle needs to be achieved to allow a three sigma kaon-pion separation up to 10 GeV/c momentum for the TORCH located 9.5 m from the interaction point. Given~ 30 detected photons per incident charged particle, this requires measuring the time-of-arrival of individual photons to about 70 ps. This paper will describe the design of a TORCH prototype involving a number of ground-breaking and challenging techniques.
