试验束设备对于研究新型探测器对粒子的响应至关重要。在DESY II测试束设施中，用户可以使用动量为1-6 GeV的电子束测试他们的探测器。为了跟踪粒子束，在每个粒子束区域都配备了EUDET型望远镜。它们提供出色的空间分辨率，但时间分辨率受到卷帘快门架构的限制，精度约为230 μ s。由于对粒子速率的需求（以及因此对轨道倍数的需求）正在增加，因此计时变得更加重要。DESY预见了望远镜的几次升级。TelePix是一个升级项目，提供精度优于5 ns的跟踪时间戳和可配置的感兴趣区域，以触发望远镜读数。小规模的原型已经在实验室和测试梁测量的特点。注入2300个电子的实验室测试表明S/N大于20。测试光束的特性表明，在超过100 mV的阈值范围和2.4 ns的时间分辨率在低噪声率的效率超过99%。
Test beam facilities are essential to study the response of novel detectors to particles. At the DESY II Test Beam facility, users can test their detectors with an electron beam with a momentum from 1–6 GeV. To track the beam particles, EUDET-style telescopes are provided in each beam area. They provide excellent spatial resolution, but the time resolution is limited by the rolling shutter architecture to a precision of approximately 230 μ s. Since the demand on particle rates–and hence track multiplicities–is increasing timing is becoming more relevant. DESY foresees several upgrades of the telescopes. TelePix is an upgrade project to provide track timestamping with a precision of better than 5 ns and a configurable region of interest to trigger the telescope readout. Small scale prototypes have been characterized in laboratory and test beam measurements. Laboratory tests with an injection corresponding to 2300 electrons show a S/N of above 20. Test beam characterization shows efficiencies of above 99% over a threshold range of more than 100 mV and time resolutions of 2.4 ns at low noise rates.
