我们展示了110 GHz高梯度加速结构的高功率测试进展。本工作的目的是研究粒子加速器在毫米波下的物理特性，以及在这种结构中的超高真空射频击穿。正在研究的装置包括一个在n模式下工作的单细胞驻波加速腔，并通过圆波导中的TMm模式馈电，而圆波导又通过高斯喇叭馈电。这些空腔将由来自兆瓦回旋加速器振荡器的纳秒脉冲供电，使其达到400兆电子伏特/米的峰值加速梯度。
We show high power test progress for 110 GHz high-gradient accelerating structures. The purpose of this work is to study the physics of particle accelerators in the mm-wave regime, as well as ultrahigh vacuum RF breakdown in such structures. The setup under investigation consists of a single-cell standing-wave accelerating cavity operated in the n-mode and fed via the TMm mode in a circular waveguide, which is in turn fed through a Gaussian horn. The cavities will be powered with nanosecond pulses from a MW gyrotron oscillator, allowing it to reach a peak accelerating gradient of 400 MeV/m.
