Description

The Micro Electron Diffraction for Ultrafast Structural Analysis (MEDUSA) beamline is a 140 keV ultrafast electron diffraction (UED) beamline currently operational at Cornell. The MEDUSA beamline specializes in the study of small samples, with electron beam probe sizes down to the single micron scale. These samples can be pumped by lasers with wavelengths ranging from IR to UV. In this proceeding, we discuss the upgrades made to MEDUSA, with a focus on a pair of foil wound solenoids we built for post sample magnification of the resulting diffraction patterns, and a measurement of their aberrations. Additionally, we detail the cryogenic compatibility changes made to allow the study of samples down to liquid nitrogen temperatures.
