Hadron Interactions Physics Laboratory

The laboratory is part of the CMS collaboration (one of two large universal detectors of elementary particles in the Large Hadron Collider (LHC) at the European Organization for Nuclear Research CERN in Geneva). A wide range of leading experiments to test the Standard Model, the Higgs boson study and the search for new particles is being carried out on this detector.

Research conducted in the laboratory is associated with the calibration of the electromagnetic calorimeter. The analysis of the experimental data is planned. The collaboration is working on a significant upgrade of the detector due to the planned increase in the luminosity of the collider (LHC). In particular, the work is underway to significantly improve the measurement accuracy of particle registration time using the mechanical electromagnetic calorimeter detector CMS. The laboratory takes part in the activity to improve the time resolution of the electromagnetic calorimeter using microchannel plates for relativistic charged particles registration.

The laboratory has conducted tests on serially manufactured microchannel plates (MCP) as well as several experimental INC models of various designs. Tests were conducted on a beam of relativistic electrons in the Institute of Nuclear Physics SB RAS. Individual samples were re-tested at the European Center for Nuclear Research (Switzerland), and the National Laboratory of Frascati (Italy). The results of these tests are important to choose the optimal design of the possible system for measuring the flight time of a charged particle. For the best samples the time measurement accuracy has been obtained around 30 ps at 70% particle detection efficiency.

The laboratory is part of The NSU interdisciplinary center of elementary particle physics and astrophysics.
