the activities are related to scientific research and experimental design work to the theme: "Development of detector devices of muon system superdirector LHCb" in the framework of cooperation between the Russian
Federation with the European Organization for Nuclear Research (CERN)
Employees of HEPD O. E. Maev and N. F.Bondar analyzed the operation of the muon system in conditions of the expected increase by an order in
luminosity of the Collider. It is shown that chambers of internal regions
M2R1, M3R1, M2R2, M3R2 in the conditions of a
tenfold increase of
background downloads will not work effectively. Therefore it is decided to replace existing chambers on chambers with a high granularity pad.
To date, the design documentation for M3R2,
M2R2 chambers with high granularity pads were
produced. Manufacturing of these chambers is planned in
For a detailed study of the characteristics of these chambers
the prototype of M3R2 chamber are made
sample is tested on proton beam of the PNPI
synchrocyclotron and is currently sent to CERN for further research.
