Description
In order to exploit the physics opportunities at the HL-LHC era, the ALICE collaboration is proposing a completely new experiment, namely ALICE 3. The ALICE 3 apparatus includes a Ring-Imaging Cherenkov (RICH) detector for high-energy charged particle identification providing Cherenkov-based timing measurements. It is equipped with an aerogel radiator coupled to Silicon Photomultiplier (SiPM) arrays readout by a custom electronics with a required single-photon time resolution at the level of 100ps. A small-scale prototype for this detector has been produced and two different front-end systems for charge and timing measurements have been assembled, equipped with Petiroc 2A ASIC and Radioroc 2 ASIC connected to a picoTDC with 3ps resolution. A custom readout board based on MOSAIC (MOdular System for Acquisition, Interface and Control) equipped with a Xilinx Artix7 FPGA has been designed for the control of the front-end boards and for data acquisition. The detector prototype has been tested with the designed electronics during dedicated beam tests at the CERN PS T10 beam line with pions and protons showing a charged particle time resolution better than 70 ps. The test beam setup and results are discussed in detail in the contribution.
