      abstract = {Ionization cooling is the preferred method for producing  bright muon beams. This cooling technique requires the  operation of normal conducting, radio-frequency (rf)  accelerating cavities within the multi-tesla fields of dc  solenoid magnets. Under these conditions, cavities exhibit  increased susceptibility to rf breakdown, which can damage  cooling channel components and imposes limits on channel  length and transmission efficiency. We report, for the  first time, stable high-vacuum, normal-conducting cavity  operation at gradients of $50\text{ }\text{  }\mathrm{MV}/\mathrm{m}$ in an external magnetic field of  three tesla, through the use of beryllium cavity elements.  This eliminates a significant technical risk that has  previously been inherent in ionization cooling channel  designs.},
