New experiment performed on Gold foil was scanned today. Gold foil #1, 30 micron thick, was film 27B. The curves look symmetric, without major features. A look at lateral and longitudinal profiles suggest that no difference between the two profiles can be detected beyond the uniformity level of the film. In this experiment, we performed a repeat film measurement without moving the gold foil, thus allowing the beam to hit the same spot of the foil. The results of the repeat confirmed the idea that differences between the two profiles are purely due to film non-uniformity.
