Improving temporal and reciprocal space resolution of the SLAC MeV-UED instrument

Description
Abstract: Ultrafast electron diffraction (UED) has emerged a powerful tool for directly observing atomic-scale structural dynamics in real time. Achieving better temporal and reciprocal space resolution is critical for expanding its scientific reach, and doing so requires sustained accelerator R&D to push the limits of beam quality and stability. In this talk, I will present methods to enhance temporal and reciprocal space resolution in the SLAC MeV-UED instrument. For temporal resolution, I will discuss an analysis of RF-induced temporal jitter and the design of a magnetic compressor that simultaneously shortens electron bunches and reduces jitter. For reciprocal space resolution, I will describe the design, characterization, and testing of a novel permanent-magnet solenoid for angular magnification. Preliminary experimental results will also be presented.
