Description
We present the Focusing Aerogel RICH-detector (FARICH) concept based on 2009-2014 studies of a FARICH prototype detector for the ALICE experiment at CERN. The aim of the project was to develop a prototype detector that would extend the momentum range of charged particle identification: up to 10 GeV/c for pion-kaon separation and up to 14 GeV/c for kaon-proton separation at the ALICE HMPID system [1, 2]. In the frameworks of this project, we proposed the FARICH prototype detector employing a multi-layer silica aerogel as a radiator. In June 2014, we tested a FARICH prototype detector based on Digital Photon Counters (DPC-DSiPM) by Phillips Company at the CERN PS T10 beam line with a particle momentum up to 6 GeV/c [3, 4]. The main performance characteristics of these prototype detectors and a comparison with a Monte Carlo simulation are presented.
In this talk, we also discuss one of the proposed versions of the FARICH concept using an MPGD GEM detector with a photo-conversion film for recording Cherenkov photons.
Proposed FARICH prototypes can be used in the development of HMPID-systems for projected heavy-ion experiments, for example, ALICE3 at CERN.
