The third generation FARICH detector is being developed. The first detector module was assembled, based on analog Silicon Photomultiplier Sensors (SiPM) with active area dimension 3mm x 3mm. The presented results of tests at the beam in 2018-2019 obtained with this prototype are consistent with expectations.
To expand the lower boundary of the momentum range for particle identification below ~400 MeV, the need for a methodology for manufacturing a four-layer focusing aerogel with the addition of zirconium oxide and a refractive index of 1.07 is discussed. The first samples of such an aerogel have already been obtained and the results of its the beam test are also presented.
