Current activity


   Currently, 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 2018, 2019.

     For a detailed study of the characteristics of  these  chambers the prototype  of M3R2  chamber are  made  (see Photo Album 9). This sample is tested on  proton beam of the PNPI synchrocyclotron and is currently sent to CERN for further research.
