| Run # | Description |
| 8768 | 10 mV LED |
| 8769 | 20 mV LED |
| 8770 | 20 mV LED, no target, radiator in, shielding changed on the beam left side, 1 gamma per 22 pulses (TDC30), 1 gamma in 3 pulses (TDC24) |
| 8771 | 20 mV LED, no target, no radiator, shielding changed on the beam left side, 1 gamma per 33 pulses (TDC30), 1 gamma in 6 pulses (TDC24) |
| 8772 | 20 mV LED, no target, no radiator, collimator hole is blocked from both the accelerator side (4" of lead) and the experimental hall (3.5" of lead) => 1 gamma per 46 pulses (TDC30), 1 gamma in 7 pulses (TDC24) |
| 8773 | 20 mV LED, no target, radiator in, collimator hole is blocked from both the accelerator side (4" of lead) and the experimental hall (3.5" of lead) => 1 gamma per 29 pulses (TDC30), 1 gamma in 3 pulses (TDC24), positron scaler 69(e+) per minute (44 e+'s background) |
| 8774 | 20 mV LED, no target, radiator in, collimator hole unblocked, beam dump for electrons => 1 gamma per 33 pulses (TDC30), 1 gamma in 3 pulses (TDC24) |
| 8775 | 100 mA peak current, 20 mV LED, DU cyl in, radiator in, collimator hole unblocked, beam dump for electrons => 1 gamma in 2 pulses (TDC24), 2n per 500 pulses (TDC24) (corrected for the efficiency, taking into account we loose some neutrons due multi hit) |
| 8779 | 100 mA peak current, 20 mV LED, HEU in, radiator in, collimator hole unblocked, beam dump for electrons => gamma in pulses (TDC24), artificial double pulse is in data steram |
| 8783 | 100 mA peak current, 20 mV LED, HEU in, radiator in, collimator hole unblocked, beam dump for electrons => scaler counts multihit events Ntot(Scaler) = /per run, Ntot(TDC4(neutrons + photons)) = /per run, artificial double pulse is in data steram in the |
