Data on
:Run with 2 Al sheets (2x0.678 mm) as bremsstrahlung converter w/o hardener.
, Detector G(1/left).Bin-by-bin subtraction of the two timing spectra after normalization:
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).
Data (detector H(2)) were normalized to the gun trigger signal. Runs 4100(thick U-taget) and 4099(MT target).
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:
Data on thick U-target,D2O and H2O from 8/17/2012:

Calibration of detector array efficiency via D2O photodisintegration (run 4111):
And the rest of the detectors:
Jitter of the PS detector and "Ilyusha" (placed on the beam) w.r.t. the gun trigger signal (run 4112):
H2O calibration run (run 4112):
And the rest of the detectors:
Run with MT target (run 4113):
And the rest of the detectors:
Thick U-target data (run 4118):
And the rest of the detectors:
Neutron data bank (two production runs 4118 and 4119 added together). Coincidences between two PMTs for each detector are shown below.
