 Again, there is no difference in the structure of the gamma peak.

 The next test I looked at is where the beam gate was open and closed.  In run 1921 the gate valve is open, and 1922 gate valve closed.

 As can be seen, there is nothing when the gate valve is closed.  This concludes that all the structure comes from somewhere after the gate valve.

 A water stop in/out test was done in trying to determine where the gamma peaks are from.  The water stop is located upstream before the 90 degree bend in the beam line.  The water stop is a pool of water that can be placed into the electron beam used to determine the beam current, cutting the current down by some ratio.  The radiator was removed for this test.  Run 1919 is with water stop out and 1920 has water stop in.

 Not much of a difference is seen, just maybe a slight shift in peaks.
