	The superconducting linac of IUAC consists of five cryostats containing 27 niobium quarter wave resonators. The prototype and the first 12 resonators were fabricated in collaboration with Argonne National Laboratory. The fabrication of the remaining resonators were carried out using in-house facilities available at IUAC. During the initial period of linac operations, problems were faced to generate higher accelerating fields in the resonators inside the linac cryostat and to reproduce the high fields at the time of beam acceleration. With systemetic efforts, all the major problems are solved and the complete linac is now operational. Since last few years, energized ion beams from linac are being delivered routinely for scheduled experiments. Among the major developmental works related to the linac operation, the vibrational damping mechansim by SS-balls, use of piezo actuator as mechanical tuner and the calculation of optimum phase focussing to control the time width of the beam bunches are noteworthy. Other two developments e.g. automatic phase locking of the resonators and auto beam tuning of the complete linac will be tested during the next beam acceleration.
