Nowadays several projects of future colliding beam experiments are considered in the world. Among them are CEPC (Circular Electron Positron Collider) in China and FCC (Future Circular Collider) at CERN (Switzerland). To perform experiments on flavour physics at energy range of the projects an excellent particle identification up to momenta of 30 GeV/c is required. Several concepts of RICH...
The latest results of data from the GRAAL experiment for coherent π π and ηπ coherent photoproduction channels on deuterium are presented. A complete kinematical reconstruction was made with the deuterons identified by the forward part of the GRAAL set-up and the π0 and η reconstructed by two photons detected by the central part of the apparatus. The results of the GRAAL data are compared with...
We produce high transparent aerogel tiles with a thickness of 20, 30 and 40 mm and n = 1.05 and aerogel tiles with a thickness of 40 or 50 mm and n = 1.03. The new procedure of thermal annealing of aerogel allows us to produce several new aerogel samples with recordable lateral sizes in 2022-2023.
In a multilayer aerogel, the refractive index and layer thicknesses are chosen so that the...
During Long Shutdown 3 (LS3, scheduled 2026-2029) a new Inner Tracking System (ITS) will be installed in ALICE for the future Run 4 data taking. At present, the ALICE ITS is at its second version, ITS2, formed by 7 layers of silicon CMOS Monolithic Active Pixel Sensors (MAPS). The 3 innermost layers are collectively referred to as Inner Barrel (IB), while the outermost ones form the Outer...
