MCD 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).
As shown by the audit of the muon detector after stopping in 2013. the LHC accelerator the outer regions of the
detector is not equipped with spare chambers M2R4, M2R3, M3R3, M4R2. Chamders
last three types were made in Italy technology different from that used
in PNPI. Experience has shown that our technology of making chambers more reliable than Italian. Therefore, the LHCb collaboration decided to
manufacture spare chambers with high reliability at PNPI. To date, under the leadership of Bocin B. V. drawing of these chambers have been modified
for PNPI technology. It is planned in December 2015, after receiving component parts from
Italy (INFN) to undertake the manufacture of
spare chambers increased reliability.
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. Work on the development of technical
documentation and the creation of laboratory samples of chambers with high granularity pad charged to MCD. Fabrication and testing of laboratory samples of these chambers is planned in 2016.
In 2015. at MCD for studying performance data of these muon chambers it was completed the creation of specialized stands: the stand of control of homogeneity of gas gain with using a radioactive source and the stand of measurement of performance characteristics of laboratory samples of muon chambers with using the proton beam of the PNPI synchrocyclotron.
