Exploration of very high gradient cavities (Conference ...To ensure adequate survival of the shortlived muons, acceleration must occur at high average gradient. The need for large transverse and longitudinal acceptances drives the design of the acceleration system to initially low RF frequency, 325 MHz, and then increased to 650 MHz, as the transverse size shrinks with increasing energy.
