35. 4. COMPASS spectrometer. New electromagnetic calorimeter. The electromagnetic calorimeter ECAL0 will supplement the COMPASS spectrometer for the GPD studies via the exclusive DVCS process µ+pµ’+p’+γ. The main tasks of the ECAL0 are the following: - together with the ECAL1 and ECAL2, to ensure a hermiticity of the setup for photons from DVCS, - to help in reduction of a background from the SIDIS process µ+pµ’+p’+π0+X, - to enlarge the kinematic domain of the DVCS registered by COMPASS. From Monte Carlo studies, the following requirements have been defined for ECAL0: – the energy range for photon detection (DVCS and background) is 0.2 to 30 GeV; – the maximum geometrical size is 2.6 × 2.6 m2 . Assuming that it is located behind of the RPD, such calorimeter will cover the polar angular range 0.3–0.6 rad; – ECAL0 should have a modular structure with the dimensions of a module cell 40 × 40 mm2, module size – 120x120 mm2(9 cells); – the required energy resolution is about 10% at 1 GeV or better; – taking into account the space limitations in the target region and the rather high fringe field of the target magnet, the total length of the calorimeter should be less than 50 cm and the photodetector should be insensitive to the magnetic field.

Time lines of the Project 2011: Participation in COMPASS data taking;         Running of both systems MW1 and HCAL1;         Development/support of MW1/HCAL1 software;      Analysis of COMPASS experimental data;        Construction and tests on ECAL0 matrix of 3x3 modules ; Design of frame and support of ECAL0; Preparation of final drawings of ECAL0; Design of LED-PIN control system of ECAL0; Design of temperature stabilization system of ECAL0; Participation in FEE design for ECAL0. 2012: Participation in COMPASS data analysis;          ECAL0 production: Module production; Frame and support production; Housing production; MAPD production and testing; LED-PIN control system production; The temperature stabilization system production; HV and LV preparation. 2013:   Participation in COMPASS data taking;       Assembly and testing of ECAL0;     Running of systems MW1, HCAL1 and ECAL0;      Development/support of MW1/HCAL1/ECAL0 software; Analysis of COMPASS experimental data; Participation in DY preparation.

37. 4. COMPASS spectrometer. New electromagnetic calorimeter. The calorimeter ECAL0 ( “shashlyk”)consists of 248 modules or 2232 readout channels. Multipixel Avalanche PhotoDiode (MAPD) will be used as photodetector. The ECAL0 includes also: the frame support, LED-PIN control system, temperature stabilization system, power supply and electronics. The ECAL0 module prototypes have been constructed and tested at the CERN East Hall T9 beam line and at COMPASS Hall.
