Experimental Reconstruction of Source 4D Phase Space Without Prior Knowledge of Transfer Matrix
Charles Zhang, Elena Echeverria, Abigail Flint +7
We experimentally demonstrate a method for reconstructing the transverse 4D phase space of an electron beam at the time of emission from downstream diagnostics of the 4D phase spac…

Atomic-scale mapping of interfacial phonon modes in epitaxial YBa2Cu3O7-δ / (La,Sr)(Al,Ta)O3 thin films: The role of surface phonons
Joaquin E. Reyes Gonzalez, Charles Zhang, Rainni K. Chen +2
We investigate the behavior of phonons at the epitaxial interface between YBa2Cu3O7-δ thin film and (La,Sr)(Al,Ta)O3 substrate using vibrational electron energy loss spectroscopy.…
