Run	Description
6686	Logic Unit in OR for Y-88 sample 130113-004
6687	Logic Unit in OR for Au-196 sample 130113-004, rate too high for DAQ
6688	Logic Unit in AND for Au-196 sample 130113-004, using Detector B and NaI, rate was 10 Hz, can't see 80 keV peak so I will increase HpGe post amp.
6689	Logic Unit in AND for Au-196 sample 130113-004, increase post amp from 20 to 50, 15 hrs 3x min 51 sec
6690	Logic Unit in OR for Ns-22 sample # 129741, post amp at 50, only 511 peak because postamp has 1 MeV peak in overflow
6691	Logic Unit in OR for Cs-137 sample # 124840, post amp at 50
6692	Logic Unit in OR for Ba-133 sample # 129789, post amp at 50
6693	Logic Unit in OR for Mn-54 sample # 129804, post amp at 50
6694	Changed post amp on HpGe Logic Unit in OR for Mn-54 sample # 129804, post amp at 20, 4 min 37 sec
6695	Logic Unit in OR for Co-60 sample # 129737, post amp at 20,
6696	Logic Unit in OR for Na-22 sample # 129741, post amp at 20,
6697	Logic Unit in OR for Cs-137 sample # 124840, post amp at 20,
6698	Logic Unit in OR for Ba-133 sample # 129789, post amp at 20, 4 min 44 sec
6699	Logic Unit in OR for Ni-57 sample # 130113-001, post amp at 20, 5 min 42 sec
6700	Logic Unit in OR for Ni-57 sample # 130113-002, post amp at 20, 5 min 2 sec
6701	Logic Unit in OR for Y-88 sample # 130113-004, post amp at 20, min sec
6702	Logic Unit in COIN for Y-88 sample # 130113-004, post amp at 20, min sec, rate is about 0.21 Hz, ended early to run nickel
6703	Logic Unit in COIN for Ni-57 sample # 130113-002, post amp at 20, rate is about 0.4 Hz, 22 hrs 55 min 8 sec, TDC16-TDC19 is not peaked around zero , the NIM2ECL translator for TDC19 does not have a square output, the problem was due to using the wrong CFD output
6704	Logic Unit in OR for Ni-57 sample # 130113-002, post amp at 20, rate is about 883 Hz, 4 min 0 sec
6705	Logic Unit in OR for Y-88 sample # 130113-004, post amp at 20, rate is about 770 Hz, 4 min 0 sec,
6706	Logic Unit in OR for Ni-57 sample # 130113-001, post amp at 20, rate is about 902 Hz, 4 min 5sec, Using correct NaI CFD channel, TDC19 should be good now will check with a coincidence run using Co-60 after taking singles measurements on the four irradiation samples
6707	Logic Unit in OR for Au-196 sample # 130113-003, post amp at 20, rate is about 4500 Hz, 37 sec,
6708	Logic Unit in AND for Au-196 sample # 130113-003, post amp at 50, rate is about 11 Hz
6709	Logic Unit in AND for Au-196 sample # 130113-003, post amp at 50, rate is about 150 Hz changed output width of CFDs from 500 ns to be about 1 usec.
6710	Logic Unit in AND for Au-196 sample # 130113-003, post amp at 50, rate is about 150 Hz inserted 1 usec delay on HpGe timing., TDC16-19 peak is -110 with an RMS of 22.5 nsec, adjusted delay near end of run
6711	Logic Unit in AND for Au-196 sample # 130113-003, post amp at 50, rate is about 150 Hz inserted 1 usec delay on HpGe timing., TDC16-19 peak is -60 with an RMS of 22.5 nsec, 51 min 38 sec
6712	Logic Unit in OR for Au-196 sample # 130113-003, post amp at 50, rate is about 4500 Hz
6713	Logic Unit in OR for Au-196 sample # 130113-003, post amp at 50, rate is about 4500 Hz
6714	Logic Unit in OR for Au-196 sample # 130113-003, post amp at 20, rate is about 140 Hz
6715	Logic Unit in AND for Au-196 sample # 130113-003, post amp at 20, rate is about 140 Hz
6716	Logic Unit in AND for Ni-57 sample # 130113-002, post amp at 20, rate is about 10 Hz,
6717	Logic Unit in OR for Ni-57 sample # 130113-002, post amp at 20, rate is about 868 Hz,
6718	Logic Unit in OR for Ni-57 sample # 130113-002, post amp at 50, rate is about 860 Hz,
6719	Logic Unit in AND for Au-196 sample # 130113-003, post amp at 50, take a longer coin run to check if the 188 keV line for the 9.6 hour half life of Au is still measurable after 2 days compare to run 6689 which is mostly accidentals from coincidence mode, ~3 hrs 21 min
6720	Logic Unit in AND for Y-88 sample # 130113-004, post amp at 50, 6 Hz
6721	Logic Unit in AND for Y-88 sample # 130113-004, post amp at 20, 17 hrs 56 min 48 sec, some problem with the HpGe spectrum, the NaI looks fine
6722	-
	runs 5703 to 6722 are not useful for coincidence, the delay inserted into the HpGe CFD would ocaisionally more the HpGe singal outside the ADC gate.
6724	Logic Unit in OR for Y-88 sample # 130113-004, post amp at 20, sec, I see peaks in the HpGe histogram, now look at timing
