GigaTracKer (GTK) 是 CERN NA62 实验的光束光谱仪。该探测器具有挑战性的设计规格，特别是峰值粒子通量高达 2.0 MHz/mm(2)、小于 200 ps 的单次命中时间分辨率以及每个跟踪平面 0.5% X-0 的材料预算。为了满足这些规格，新技术特别应用于硅混合时间戳像素技术和微通道冷却领域。本文介绍了探测器的设计并报告了所实现的性能。
The GigaTracKer (GTK) is the beam spectrometer of the CERN NA62 experiment. The detector features challenging design specifications, in particular a peak particle flux reaching up to 2.0 MHz/mm(2), a single hit time resolution smaller than 200 ps and, a material budget of 0.5% X-0 per tracking plane. To fulfil these specifications, novel technologies were especially employed in the domain of silicon hybrid time-stamping pixel technology and micro-channel cooling. This article describes the detector design and reports on the achieved performance.
