Goals

measure the Beam spot size on target

Measure the Transmission

Measure Positrons produced

Runs

Energy Estimation on later day runs

[Energy extrapolation ]

When RF knob was at 4.19, the energy is about 11.56 MeV with rms energy spread of 0.66 MeV

Setup

Detector2 (NaI-2 , S/N 60002-8292-I) is at beam left. It needs 1080 V. IAC_NaI_Detectors#Det2

Detector3 is at beam right. It needs 1060 V. IAC_NaI_Detectors#Det3 

(When taking down the experiment It was observed that NaI-1, S/N 60002-8454-I was on the Beam right location).
NaI-3 was replaced with NaI-1 after run#3663.
