Excellent Timing Cherenkov Light Detection for Dual-readout High-granularity Calorimetry

We are developing a Cherenkov detector aiming for applications in the next-generation calorimetry. It is a calorimetry that combines dual-readout and high-granularity with excellent timing capability. This work is to prove the concept of the Cherenkov detector utilizing a resistive plate chamber (RPC) with Diamond-Like Carbon as resistive electrode. The first prototype was tested with β-rays and cosmic-rays. This paper discusses the behavior of the charge spectrum and the time resolution of the first prototype.
