DIRECT ELECTRON-LIQUID ENERGY LOSS SPECTRA MEASUREMENTS USING A LIQUID MICRO-JET

Electron transport through liquids plays a critical role in a number of emerging applications in medicine, particle detectors and nanomaterials. Currently, conducting direct electron-liquid scattering experiments in vacuum conditions poses significant challenges due to the high vapour pressure of liquids and multiple scattering effects. In this work, we present a new electron-liquid scattering experiment that utilises a liquid micro-jet to provide a stable scattering surface for an electron beam under vacuum conditions. Initial measurements are made and compared to existing theory using a Monte Carlo simulation and their limitations are discussed.
