Advanced Experimental Nuclear Physics Research

A) Upgradation of Experimental Facility for VEC
The main interest of the present day nuclear structure studies is to carry out “complete spectroscopy” and “new symmetries” and shapes of nuclei around the stability line on one hand and on the other hand to explore new structure information of nuclei away from stability line. The above goals can be achieved with suitable in-beam and off-line setup of state of art Clover Ge detectors, fast scintillators and conversion electron spectrometer and other particle detectors, to be combined as per the experimental requirement. This will broaden the scope of nuclear structure studies using gamma spectroscopy with the cyclotrons at VECC. It has been observed that nuclear decay process is susceptible to the environmental conditions and it is of current interest to study nuclear decay rate change with temperature, pressure and in high charge state. Experimental facility for studying these decay processes under extreme condition may help us in understanding the decay rates and nuclear abundances in astrophysical and geophysical environments.

B) Superconducting Cyclotron Utilisation : PHASE-II
A few major users’ facilities and detector systems (general purpose reaction chamber in beam line-1, charged particle detector array, high energy gamma array, neutron multiplicity detector, penning trap, material science / nuclear chemistry facilities etc.) have already been developed under the ‘superconducting cyclotron utilisation project  taken up during X and XI plan periods. The proposed new phase-II project is aimed  at adding a few new facilities and detector systems , which are complimentary in nature with the  facilities already developed, and will augment the scope of the superconducting cyclotron utilisation.  The facilities which are being planned to be developed are large high vacuum reaction chamber for beam line – 2, neutron time of flight (n-TOF) spectrometer, backward part of the charged particle detector array, high resolution gamma ray spectrometer,  high efficiency high resolution gamma multiplicity array of LaBr3 crystal.

C) Advanced Experimental Nuclear Physics Research/Advanced Data Acqusition Electronics and Software Technology
It proposes to implement the global time-stamping mechanism and software development for global event reconstruction for multiple and independent data acquisition system for integrating various detector arrays of different response time and achieving low dead-time.  It proposes to explore the use of parallel and functional programming approaches for the online and offline data analysis software on presently available computer architecture. The project however proposes to continue upgradation of the existing technology based systems at VECC for smooth transition to new paradigm. It also proposes to implement an FPGA based 8-Ch readout system. Various fault-tolerant techniques and algorithm for transient nature of fault arising due to radiation or other external effect on configurable electronic devices like FPGA would be experimented on this readout chain.
