Description
High power input often leads to frequency deviation that cannot meet the high-precision frequency control requirements of keV Ultrafast Electron Diffraction (UED) compression cavities. In this paper, we propose new solu-tions for reducing heat generation and frequency devia-tion based on modifications to the cavity design and power input method, building upon the design of the orig-inal elliptical cavity. These solutions have been verified through simulation calculations. In pulsed input mode, the cavity temperature rise is within 2℃, and in continu-ous wave mode, the new cavity design can withstand temperature rises of up to 20℃, both of which meet the requirements of practical engineering.
