2n preliminary data analysis

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).

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). [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:

Data on thick U-target,D2O and H2O from 8/17/2012:

Detector layout:

Det E | 0.106 | sr \\ DetM & 0.118 & sr \\ Det F & 0.096 & sr \\ Det G & 0.063 & sr \\ Det H & 0.033 & sr \\ Det K & 0.019 & sr \\ Det I & 0.011 & sr \\ 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.
