国际上的Muon电离冷却实验(MICE)旨在演示通过电离产生的Muon束的横向冷却。小鼠的电离冷却通道需要8个201 MHz的正常导电射频腔来补偿冷却通道中的纵向束流能量损失。本文介绍了LBNL在改善小鼠射频腔在强磁场作用下的性能的电抛光工作的最新进展，并用SLAC的ACE3P程序进行了射频模拟，研究了外磁场对腔内和耦合区的多脉动效应的影响。
The international Muon Ionization Cooling Experiment (MICE) aims at demonstrating transverse cooling of muon beams by ionization. The ionization cooling channel of MICE requires eight 201 MHz normal conducting RF cavities to compensate the longitudinal beam energy loss in the cooling channel. In this paper, we present the recent progress on the electropolishing work on MICE RF cavity at LBNL, which is intended to improve the cavity performance in the presence of strong external magnetic field, and the RF simulation with SLAC’s ACE3P code to study the multipacting effects in the cavity and at the coupler regions with the influence from the external magnetic field.
