Poster Particle identification


Mr Nikolay Podgornov (BINP)


A high-performance particle identification (PID) system is essential for the successful realization of the broad physics program at the future Super C-τ Factory in Novosibirsk. The main requirements for the PID system are as follows: good π/K-separation in the entire operational momentum range and good μ∕π-separation in the momentum range from 0.3 to 1.2 GeV/c. The RICH detector based on focusing aerogel radiator (FARICH) meets all these requirements. The FARICH method is described, and the beam test results are presented.


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.
