Descripción
The rapid evolution in high-luminosity colliders necessitates ultra-precise timing detectors capable of picosecond-level accuracy. This presentation explores the development of a distributed timing architecture based on deterministic protocols, as the High Accuracy Default PTP Profile of IEEE1588-2019 – a.k.a. White Rabbit (WR), to address stringent timing demands in next-generation particle detectors. Our primary objective is to implement a scalable timing distribution system that delivers a clocking signal enabling an absolute time reference among different detectors. The system automatically copes perturbations influencing the distribution network, as thermal cycles, to overcome inherent instabilities and limitations. The stable common notion of time synchronizes measurements between pre-target and post-target detectors, improving the fidelity of particle flight time measurements and enabling high-resolution 4D tomography.
The presentation introduces some key aspects and background for 4D timing detectors and presents preliminary results that include benchmarking commercially available (COTS) and custom solutions to assess limitations in jitter, phase stability, and determinism. The proposed system integrates prototype 4D detectors featuring LGAD sensors and ETROC2 readout chips, synchronized through the WR platform. We present our experience and efforts with WR technology analysis, equipment procurement, prototype development, functional testing, and a final review of performance limitations.
