Superconducting LINAC booster is modular machine which consists of 7 cryomodules each consisting four quarter wave resonators and one superbuncher module. The control system is a mixed distributed control system. Geometrical distributed system architecture has been followed for RF control. RF control has four local nodes( RF LCS) each nodes catering to two cryostat. Two additional nodes are made for beam line system and cryogenics distribution system, making it a systematic distribution system. The system is developed on Linux operating system but the software is portable on Linux and Microsoft windows. The software is developed in two layers namely scanner and operator interface. Scanners interacts with the interface hardware. All scanners are developed in JAVA , which is very challenging job looking towards the feature of JAVA. Various issues regarding this were closely investigated and solved to overcome the deficiency of JAVA .A micro-controller based board has been developed for cryogenics line distribution system. Different subsystems of the control system has been developed independently. A complete integration of the system will be completed before Dec 2012.

The superconducting LINAC booster at Pelletron Linac Facility(Mumbai), has been fully operational since July 2007. The Liquid Helium Refrigeration plant for the LINAC has been upgraded to enhance the refrigeration capacity to ~450 Watts at 4.5K without LN2 pre-cool, from the earlier capacity of ~300 Watts. All beam lines in new user halls have been commissioned and new experimental setups have been added. Several experiments have been carried out using beams of 12C, 16O, 19F, 28Si, 31P. The QWR cavity is designed for β=0.1 and hence it is difficult to accelerate lighter beams. Due to growing interest in studying Li induced reactions on fissile targets at energies higher than 55 MeV, we have recently accelerated Li beam using four cryostat modules. Starting with 40 MeV Li beam from the pelletron, 56 MeV beam was successfully delivered at target station for a test experiment.

The HIE-ISOLDE project represents a major upgrade of the ISOLDE facility with a mandate to significantly improve the quality and increase the intensity and energy of radioactive nuclear beams produced at CERN. The project will expand the experimental nuclear physics programme at ISOLDE by focusing on an upgrade of the existing REX linac with a 40 MV superconducting linac comprising thirty-two niobium-on-copper sputter-coated quarter-wave resonators housed in six cryomodules. The new linac will raise the energy of post-accelerated beams from 3 MeV/u to over 10 MeV/u. The upgrade will be staged to first deliver beam energies of 5.5 MeV/u using two high-β cryomodules placed downstream of REX, before the energy variable section of the existing linac is replaced with two low-β cryomodules and two additional high-β cryomodules are installed to attain over 10 MeV/u with full energy variability from as low as 0.45 MeV/u. An overview of the project including a status summary of the different R&D activities and the schedule will be given here.
