Abstract:
The SMRD detectors (counters) of the T2K experiment are assembled into bigger units called modules. The final design of the modules was elaborated in the Division of Scientific Equipment and Infrastructure Construction (DAI) of the H.Niewodniczański Institute of Nuclear Physics Polish Academy of Sciences (IFJ PAN) in Krakow, Poland. The methods of the module assembly and stabilization inside the T2K magnet were also worked out. Installation procedures of the modules including cable handling were proposed as well. All elements and tools for the assembly, stabilization and installation of 440 SMRD modules had been produced in Poland in 2008. The SMRD modules had been assembled at J-PARC in Tokai and then installed in the T2K experiment in 2009.
