Description
The CUPAC NE Collaboration involves 20 universities, institutes and colleges from the North Eastern
states of India. Our collaborators from Indian national laboratories (BARC, IUAC, UGC-DAE CSR) and
International laboratories# bring much needed experience and expertise in experimental techniques and stellar model
codes critical to success of CUPAC mission. The long term goal of CUPAC is to construct a world class accelerator
facility in the NE region [1]. The proposed accelerator is a 5 MV Pelletron accelerator with an ECRIS injector.
Research domains include PIMS (Positive Ion Mass Spectrometry), nuclear astrophysics, neutron science including
AD-BNCT (Accelerator Driven Boron Neutron Capture Therapy) and SHIM (Swift Heavy Ions in Materials) with
high intensity inert/heavy ion beams.
The proposed accelerator could uniquely augment national research capabilities in investigation of nuclear
astrophysics reactions at (i) Gamow peak in ~200 keV to 100 MeV energy range and (ii) Inert isotopes like Ne,
Ar etc and providing high intensity heavy ion beams including group-VIII elements @ ~100 MeV for SHIM
studies.
Currently, the collaboration is implementing R &D projects in AD-BNCT, PIMS and investigation of neutron
source in AGB stars [2, 3]. Considerable efforts were also put in designing a gas jet target coupled with RMS
for nuclear astrophysics, ion optics of accelerator and kinematically focused neutron source at IUAC.
