Detector Right -> CH5

Beam left Scintillator (between Q9 and Q10)-> CH9

Scintillator 1 (right next to the beam exit at the the 90 deg) -> CH2.

Battery -> CH13.

Note: There were some changes going on during the experiment. The above setup was according to the sent up on 27th of Jul. All the changes were recorded.

TDC input

According to the setup on 27th:

CH0->start from the gun.

CH1->95 ns delay of the start from gun.

CH5->NaI Left.

CH7->NaI Right.

13->Gate for signal (generated whenever there is a electron gun pulse, then fast cleared if there is no coincidence).

CH9-> discriminated output of NaI Left.

CH10-> discriminated output of NaI Right.

Scaler

The gun pulse connected to CH1 of the scaler . I thought I put it to CH0, may be somebody changed it.

HV power supply

We used 2CAEN Mod. N471 power supply. There are 2 of them. 2 for NaI and one for Scintilator1.

Power supply left, top channel-> NaI left

Power supply left, bottom channel-> NaI right

Power supply right, top channel-> Scintillator 1
