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

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,

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

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
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
6729	Logic Unit in AND for Na-22 source # 129743, post amp at 20, rate is about 32 Hz changed output width of CFDs from 1000 ns to be about 500 nsec., HpGe discriminator at 50 mV and NaI at 30 mV
6730	Logic Unit in OR for Ba-133 source # 129789, post amp at 20, rate is about 350 Hz .
6731	Logic Unit in OR for Ba-133 source # 129789, post amp at 50, rate is about 1 kHz ,HpGe discriminator at 10 mV and NaI at 10 mV. can see ~80 keV peak from Ba-133
6732	Logic Unit in OR for Ba-133 source # 129789, post amp at 50, rate is about 800 kHz ,HpGe discriminator at 20 mV and NaI at 20 mV.

 Somehow at delay switch was flipped up to the 1 usec position instead of the 0.1 usec position on the HpGe 

Hazards of taking data in a common use environment I guess

I didn't notice it before because the HpGe output was barely making it into the gate

Improved coincidence setup
