The Superconducting Linear Accelerator as a booster of existing 15 UD Pelletron accelerator is under construction at IUAC. The heart of superconducting linac is three cryomodules, each one housing eight quarter wave niobium cavities. At present the first linac module along with superbuncher and rebuncher cryostat are integrated with zero degree beam line. Design and fabrication of two more linac modules under progress. A VME based CRYO-DACS has been developed to monitor and control parameters of cryostat. The total load at 4.2 K for complete system including locally developed liquid helium distribution line as well as break up load for each cryomodules has been measured. The measured load in linac module is higher than the design value. A detailed thermal analysis has been carried out using temperature profile for each component of cryomodules. Extra load is mainly contributed by aluminum structure,drive coupler and additional radiation load. The present paper will be highlighting the operating experience on cool down of linac as well as thermal performance of each cryo module. Scope of improvement on future linac cryo module to reduce the static load will also be covered.

Indus-2 is a 2.5 GeV synchrotron radiation source under commissioning at this center. Beam injection trials in the storage ring began in August 2005. Beam diagnostics systems played an important role during commissioning of the storage ring. Beam diagnostic systems installed in the machine include beam profile monitor, orbit measurement system, wall current monitor, DCCT, striplines, tune measurement system and sighting beam line. This paper describes the diagnostic systems, experience of operation of these systems during commissioning, results obtained and the present status. During the initial stages of beam injection and circulation in INDUS-2 wall current monitors, beam profile monitors and sighting beam line proved to be of utmost help. In the current stage of near routine beam operation, the main focus has shifted to the measurement of beam parameters with the objective of improving beam current and lifetime. A study of beam orbit measurement was recently taken up. The beam orbit was measured before and after generating an orbit perturbation. A study of betatron tune measurements has been initiated.
