Matching Section Optics Design for the MeV Ultrafast Electron Beam Experimental Facility

This paper introduces the design and optimization of the matching section beamline for the ultrafast electron research platform at Huazhong University of Science and Technology (HUST). The matching section serves as a connection between the main beamline and the beam physics research beamline, aiming to achieve efficient and precise control over the electron beam trajectory and parameters. To evaluate its performance, particle tracking simulations using GPT software were conducted. When the beam is set at 3 MeV and 1 pC charge, the matching section is capable of compressing the bunch length to approximately 50 fs. This level of compression is crucial for ultrafast electron research applications, as it enables the study of phenomena that occur on extremely short time scales, demonstrating its effectiveness in achieving precise beam control and compression.
