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
