Dr. Dinesh Kumar Srivastava, the Director of our Centre, today inaugurated the upgraded Silicon Detector Laboratory with a new clean room facility and a new Neutron Detector Fabrication Laboratory. 

The new clean room facility at the Silicon Detector Laboratory will be used by the experimenters for the storage and performance testing of the very thin, segmented silicon detectors to be used in the Charged Particle Detector Array (CPDA). The CPDA is one of the major facilities that VECC is building for the effective utilization of the Super Conducting Cyclotron at our campus. “The clean room that we have built is of class 1 00 000. If you go outside this room, you may find 10 times more airborne particles in a cubic foot of air of size greater than 0.5 microns,” interpreted Dr. Saila Bhattacharya, Head of the Physics Group. The CPDA consists of 24 “telescopes”, each of which consists two thin (50 micron & 500 micron / 1mm) strip detectors and 4 CsI crystals. For mounting the detectors in a telescope, the experimenters require clean environment.

The Neutron Detector Fabrication Laboratory, located at the roof top of the Silicon Detector Laboratory, will be used for the assembly, fabrication and testing of liquid based scintillator detectors. These detectors will form a neutron time of flight (TOF) array, to be installed in the beam-line of the super conducting cyclotron beam hall. The lab will also be used for the fabrication and testing of detectors that VECC will contribute to the international FAIR project at GSI, Germany. VECC, along with other Indian collaborators, will develope 50 neutron detectors for MONSTER (MOdular Neutron SpectromeTER) array for the DESPEC experiment at FAIR.
