Revision as of 22:06, 1 November 2013
Goals
Use NaI to measure Y-88 coincidence lines of 1836 and 898 keV
Runlist
Run | Description | |
6559 | Coincidence run with Na-22 1 uCi source # 129742, ADC7 = HpGe, ADC3 = NaI, TDC16 = HpGe, TDC19 = NaI, Na-22's 1.2 keV photon is in channel 3600 for the HpGe detector and channel 500 for the NaI; need to decrease gain on HpGe so Y-88's 1.8 keV photon is in the ADC range | |
6560 | Changed HpGe spec amp integration from 0.5 usec shaping time to 0.25 and ran in singles mode | |
6561 | Running in coincidence mode, rate changed from about 70 Hz to about 2 Hz | |
6562 | Running in OR mode with activated Y-88 sample #130100-010 | |
6575 | same conditions as run 6571 but with activated Y-88 sample #130100-010 |
Calibration
calibrate with Na-22 (511,1200), Co-60 (1.2, 1.3), Mn-54 (), Cs-137 (662 keV)
Calibration runs
Cd=109 has coincidence lines at 203 & 250 keV
Run | Description | |
6567 | Singles run with only NaI detector and Co-60 source | |
6568 | singles runs with only HpGe detector and Co-60 source | |
6569 | OR mode, both detectors, 3k DAQ trigger rate. Co-60 1 uCi source # 129739 | |
6570 | Running in OR mode with Mn-54 source # 129806 700 Hz | |
6571 | Running in OR mode with only NaI in trigger and Mn-54 source, increased threshold from 10 mV to 40 mV to count more high energy photons | |
6572 | same as run 6571 but using Na-22 1 uCi source # 129742 | |
6573 | same as run 6571 but using Co-60 1 uCi source # 129739 | |
6574 | same as run 6571 but using and used Cs-137 1 uCi source #129793 |
