EXPERIMENTAL CHARACTERIZATION OF A 700 MHZ β=0.47 5-CELL SUPERCONDUCTING CAVITY PROTOTYPE FOR PULSED PROTON LINAC

摘要

A 700 MHz 5-cell elliptical cavity has been developed to accelerate a high intensity proton beam in the lower energy part of a superconducting pulsed linac, starting at 80 MeV. This cavity is stiffened in order to minimize the Lorentz detuning which limits high field pulsed operation of the flatter, low beta cavities. Cavity performance in vertical cryostat is reported. Measurements of the RF response to mechanical excitation are presented.
