The Institute for Nuclear Research of the Hungarian Academy of Sciences (ATOMKI) and the Institute of Physics of University of Debrecen are two neighbour institutes in Debrecen working closely together on CMS. The groups – in collaboration with CERN and the Wigner RCP (formerly KFKI RMKI) in Budapest – are responsible for the development, construction, installation, commissioning, data-taking and analysis of the CMS Muon Barrel Alignment system since 1994. Since the start of data taking in 2009, the continuous operation, maintenance and small upgrade of the system has been provided by the group, which also participates in the development of the internal alignment for the new GEM chambers for the Phase-2 Upgrade.
A small group at ATOMKI in collaboration with other Italian institutes (INFN Sezione di Napoli, University of Naples Federico II) is responsible for the Fiber Optical Sensor (FOS4CMS) group at CMS, which is responsible for the data acquisition and control-and-safety of a system of more than 1000 environment sensors in the CMS detector cavern. A team from University has made significant contributions to the Tracker project, particularly to the Pixel Tracker throughout Runs 1 and 2 of the LHC, in the calibrations by offline analysis of data with dedicated software, in the maintenance by periodically monitoring the performance, and in the operation by regular participation in data taking.
A member from University of Debrecen team took part in the ME4/2 Upgrade Project. Working with the team of the “CSC factory” at building 904 they completed the mechanical construction of the ME4/2 chambers, which was followed by testing, installing and commissioning the new chambers at P5. A team from the University of Debrecen will provide expertise in HV power supplies development and electronics irradiation to validate the prototype of muon system’s upgraded barrel region for HL-LHC conditions. The CMS DT group will procure a HV prototype from CAEN, which produced the 250 magnetic-tolerant radiation-hard modules (A877) used now in UXC.
