为NA 62实验中的束流跟踪而研制的时间标记混合硅像素探测器已在CERN的专用测试束中用10 GeV/c强子进行了测试。测量包括时间分辨率，检测效率和像素之间的电荷共享，以及由于偏置电压变化的影响。在200 μm厚的硅传感器上，采用像素级双稳放大器和基于列末DLL的时间-数字转换器，测量出小于150 ps的时间分辨率。
A time-tagging hybrid silicon pixel detector developed for beam tracking in the NA62 experiment has been tested in a dedicated test-beam at CERN with 10 GeV/c hadrons. Measurements include time resolution, detection efficiency and charge sharing between pixels, as well as effects due to bias voltage variations. A time resolution of less than 150 ps has been measured with a 200 μm thick silicon sensor, using an on-pixel amplifier-discriminator and an end-of-column DLL-based time-to-digital converter.
