out | 18.8 | Full open | too much pile-ups | tuned to fc2 10 MeV |
Bend the beam by 45 degree
When we bend the beam by 45 degree, there were too much current on the scintilator. Gun grid voltage is lowered to lower the current.

Play with quads
same tune as above, except change in some of the quads.
Change quads: q4, q5, q6, q7, see the change in the rate.
