If we compare the photon flux from the two runs with DU target
run 2467
and
run 2506
The average photon flux increased from 90 to 350 and the ratio is 350/90 = 3.9.
The number of neutrons used to do narmalization, i.e. the sum of the number of neutrons in three detectors placed at 0 deg left, 90 deg bottom and 0 deg right changed as follows:
run 2467: SUM(0-90-0) = 518 neutrons
run 2506: SUM(0-90-0) = 2195 neutrons
