The superconducting LINAC booster of IUAC consists of five cryostats housing a total of 27 Nb quarter wave resonators (QWRs). The QWRs are phase locked against the master oscillator at a frequency of 97 MHz. Cavity frequency tuning is done by a Helium gas based slow tuner. Presently, the frequency tuning and cavity phase locking is done from the control room consoles. To automate the LINAC operation, an automatic phase locking system has been implemented. The slow tuner gas pressure is automatically controlled in response to the frequency error of the cavity. The fast tuner is automatically triggered into phase lock when the frequency is within the lock window. This system has band implemented sucessfully on a few cavities. The system is now being installed for the remaining cavities of the LINAC booster.
