Data on [math]MT target/D_2O[/math]:

Run with 2 Al sheets (2x0.678 mm) as bremsstrahlung converter w/o hardener. [math]E_e = 10.5 MeV[/math], Detector G(1/left).

Data on thick U-target and D2O from 8/13/2012:

Data (detector G(1,2)) were normalized to the gun trigger signal. Runs 3999(D2O) and 4001(no target), and 4011(thick U-target) and 4012(no target).

Data on thick U-target,D2O and H2O from 8/16/2012:

Data (detector F(1)) were normalized to the gun trigger signal. Runs 4097(D2O) and 4098(H2O), and 4011(thick U-target) and 4012(no target). [math]E_e = 10.5 MeV[/math]

Data (detector H(2)) were normalized to the gun trigger signal. Runs 4100(thick U-taget) and 4099(MT target). [math]E_e = 10.5 MeV[/math]

Photon flux study.

The current we were running at (3 sheets of Al):

And when we asked the operator to cut the electron current twice, our photon flux monitor showed:
