Venue: room 347, bld. 215, Veksler and Baldin Laboratory of High Energy Physics
Seminar topic: «Hadron calorimeter calibration in a carbon beam with an energy of 4.5 GeV per nucleon»
Speaker: Oleg P. Gavrishchuk (Leading Researcher, the MPD Multi-Purpose Detector Investigation Department, Sector #2 for elementary particles identification)
Abstract:
The Hadron calorimeter was manufactured for the BM&N setup at the JINR Nuclotron as forward calorimeter (ZDC) started since 2015.
The hadron calorimeter consists of 68 modules with a sizes of 150×150 mm2 and 36 modules of 75×75 mm2. The calorimeters modules consist of 64 scintillator layers and lead, 5 and 10 mm thick respectively, which corresponds to 4.8 absorption lengths.
The results of ZDC calibration in a carbon nuclear beam with kinetic energy of 4.5 GeV per nucleon are presented. Preliminary equalization of signal amplitudes from individual modules was performed in cosmic rays with transverse trigger.
