keyword=Compton collimator and lead filter changed
Since the photon rates looked so good, the Compton photon beam collimator has been changed to 2 cm diameter collimator and the lead synchrotron filter has been changed to a 1 mm lead filter (changed from a 0.6 cm diameter collimator and a 3 mm lead filter).
