NEW RF MEASURING SYSTEM FOR CAVITY CHARACTERIZATION

New computer based, mobile measuring system for both laboratory and on line characterization of superconducting cavities has been put into operation at LNL. The system covers the frequency range from 80 to 350 MHz and represents a reliable, fast and precise instrument for cavity testing. The list of automatic and semiautomatic procedures includes line calibration, frequency sweep, decay time measurement, Q (Ea) curve acquisition and pulse conditioning.
