Abstract

TEMPUS is a new detector system being developed for photon science. It is based on the Timepix4 chip and, thus, it can be operated in two distinct modes: a photon-counting mode, which allows for conventional full-frame readout at rates up to 40 kfps; and an event-driven time-stamping mode, which allows excellent time resolution in the nanosecond regime in measurements with moderate X-ray flux. In this paper, the initial prototype, a single-chip device, is introduced, and the readout system described. Moreover, and in order to evaluate its capabilities, some tests were performed at PETRA III and ESRF for which results are also presented.

摘要

TEMPUS是一种正在为光子科学开发的新型探测器系统。它基于Timepix4芯片，因此可以在两种不同模式下运行：光子计数模式，允许以高达40 kfps的速率进行传统的全帧读出；以及事件驱动时间戳模式，在中等X射线通量的测量中，该模式在纳秒范围内具有出色的时间分辨率。本文介绍了初始原型，即一种单芯片设备，并描述了读出系统。此外，为了评估其性能，在PETRA III和ESRF进行了一些测试，本文也给出了测试结果。
