New modifications in 15 UD pelletron at Nuclear Science Centre

The 15 UD pelletron at NSC has been operational and performed well during the last 11 years. There have been major modifications performed for up gradation of pelletron system over this period. Major up gradations which have been implemented are new resistor network system for voltage gradient, doublet to singlet unit conversion for accelerator units, turbo pump based gas stripper system etc. In addition accelerator mass spectroscopy program has also been started. A new multi-cathode source, Wien filter etc. have been procured and will be added soon in the system. An overview of the most significant up gradations undertaken and other activities for the system are being reported in the present paper. (author)
