Abstract

The authors have developed two models of a 150 MHz quarter wave resonator - one with optimum beta equals 0. 10 and one with optimum beta equals 0. 21. These are lead-plated copper structures. The prototype beta equals 0. 10 resonator was tested successfully a year ago and gave average accelerating fields of 3. 5 MV/m with 4. 2 W dissipated. It is similar to the resonator developed by Ben-Zvi and Brennan (1983). Several more of this model have been tested. A prototype beta equals 0. 21 resonator has been completed, but weld flaws have prevented definitive tests. In order to minimize surface electric fields in the high-beta resonator, there were some modifications in the drift tube shape beyond those required to change the optimum beta. These quarter wave resonators have a wide transit time factor curve and are extremely rigid mechanically. Variations in eigenfrequency due to mechanical vibrations are less than 1 Hertz. Maximum attainable fields are limited by field emission.
