Detector Development for High Energy Physics Research (Proposed)

A) Study of high energy heavy ion collisions at FAIR using  high rate micro-pattern detectors
The Experimental High Energy Physics and Applications (EHEP&A) group at VECC has been engaged in building advanced detector systems for EHEP and other applications. During Xth and XIth plan periods, VECC has built a specialized type of detector system named Photon Multiplicity Detector (PMD) for the experiments at CERN-Geneva and BNL-USA. The detectors have brought about valuable results in terms of developing detector technology and physics knowledge. A project undertaken in the XIth plan has made first attempt to use the acquired technology in the field of medical imaging. In XIth plan, another project on detector development has been completed in which we have demonstrated that locally made Bakelite sheets can be used for building the Resistive Plate chamber for INO experiment.  As an extension of RPC a system called Multi-Gap RPC (MRPC) has been developed as a prototype of TOF-PET system. During this period, extensive R&D has been performed on an advanced type of gas-detector technology called GEM.

The acquired knowledge will be used in developing tracking chambers for muon detection (MUCH) in the Compressed Baryonic Matter (CBM) experiment at the upcoming FAIR facility in Germany. The scope of the present proposal is to complete R&D and build prototypes for CBM-MUCH. The jobs involve R&D on GEM-based chamber development, development of readout system using self-triggered ASIC, fabrication of pre-production prototypes including readout. Other major component of this proposal is to extend the present knowledge gathered in XIth plan period on the application of MRPC and GEM for TOF-PET and X-ray imaging respectively. Full-fledged demonstrators will be built for both the systems using phantoms. The R&D for CBM-GEM and medical imaging detector involve same activities.

B) R&D for large size Bakelite RPCs and participation in INO Collaboration work
The Sub Project   deals with the development of another type of detector which is required for the Iron-Calorimeter at the upcoming INO experiment. INO requires 2m x 2m RPCs and a dedicated R&D effort must be undertaken to establish the feasibility of building such detectors from locally made bakelites. It is also required that proper industrial sources should be found where a large number (~9000) of RPCs could be built. In the proposed project detailed procedures and steps will be undertaken so that the feasibility and methodology could be established towards building 2m x 2m large RPCs for INO. Necessary testing and characterization will be part of this subproject
