The schematic of the MeV UED setup at TTX facility. (1) Photocathode RF gun. (2) Magnetic solenoid. (3) Sample chamber. (4) Deflecting cavity. (5) Steering coils. (6) 3 m drift tube. (7) Detector chamber.
A simulated diffraction pattern (a) and the corresponding scattering intensity (b). See text for details. (c)–(f) show changes in widths and separations of the (111) and (200) rings when one parameter is changed while others remain roughly the same.
Measured diffraction pattern (a) and corresponding scattering intensity (b) retrieved from the indicated triangular area in (a), together with the simulated one. See text for details.
Estimated electron pulse parameters entering the sample.
