Camera Trig
Tune the beam for 15 MeV range, see the beam with camera. Get camera triggering.
Tune The Beam for 11-12 MeV

Beam Current 0 degree FC: 
Beam Spot at 0 degree OTR screen: 
Scintillator pulse count
Scintillator is located at the end of the 90 degree beamlien (after the thin window). Rates measured with W1 in and out.
| Energy Switch | Out (High En) |
| Solenoid 1 | 6.8 A |
| Solenoid 2 | 1.2 A |
| Gun Hor | 0 A |
| Gun Ver | +0.2 A |
| Output Hor | +1.2 A |
| Output Ver | 0 A |

| Q6 (A) | -3.5 |
| Q7 (A) | -6.1 |
| Q8 (A) | 0 |
| Q9 (A) | +0.6 |
| Q10 (A) | -0.4 |
| W1 | Time (s) | D1 (A) | Jaws | Counts | counts/second | conditions |
| in | 209.1 | 0 | Full open | 1842 | 8.81 | tuned to fc1 10 MeV |
| out | 192.5 | 0 | Full open | 1052 | 5.46 | tuned to fc1 10 MeV |
| in | 226 | 2.5 | Full open | 2082 | 9.21 | tuned to fc2 1 MeV |
| in | 205 | 18.8 | Full open | 1784 | 8.7 | tuned to fc2 10 MeV |
| out | 18.8 | Full open | too much pile-ups | tuned to fc2 10 MeV |
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.
