Description
We propose a novel MeV UED beamline design based on a normal-conducting very-high-frequency (VHF) electron gun that generates a high-quality electron beam at a megahertz (MHz) repetition rate. Beam compression and time-of-flight (TOF) control are achieved using an alpha-magnet. Simulations show compression of the 4.1 fC electron beam to a duration of 4.7 fs RMS, with a TOF jitter of 1.9 fs RMS, alongside normalized transverse emittances of 5.6 nm·rad in the x-direction and 5.2 nm·rad in the y-direction. This design substantially enhances both the signal-to-noise ratio and temporal resolution of the UED beamline, establishing a robust foundation for the future development of UED facilities.
