resonance:共振,振动或波动频率匹配时产生的增强现象superconducting radio-frequency cavity:超导射频腔,用电磁场给粒子束加速particle beam:粒子束tune:调谐,把设备调整到合适的频率detuning:失谐,偏离正确频率disturbance:扰动,影响系统稳定的变化liquid helium:液氦,用来冷却超导设备pulse:脉冲,一次短促的能量或信号输出cooling cost:冷却成本unplanned shutdown:非计划停机shared framework:共享框架low-level radio-frequency control:低电平射频控制beam stability:束流稳定性Reducing the field between pulses would lower power use, but it would also make resonance control harder.Reducing the field would lower power use,意思是「降低脉冲之间的场强会减少用电」。后面的 but 带出转折:这样做也会让共振控制更困难。句子真正要表达的是:节能和稳定控制之间存在技术难点。1pip2.fnal.gov
