|
| To protect HPGe and 3He tubes from high intentsity primary beam, HV of these detector are off and the HPGe will be dismounted. |
|
Mon Jul 18 09:32:50 2016, Shintaro Go, HV controls
|
You can start applying HVs on the detectors using macro on the control-computer.
If you have already signed in the computer that controls mpod,
1. Type http://192.168.13.239/ to monitor the status of HV. |

Mon Nov 7 06:55:01 2016, NTB, SG, HPGe Fill line to D4 replaced
|
HPGe fill line to D4 replaced only small leak (overflow) once Ge is full.
Solenoid was also wrapped to no effect. AIDA DAQ still stops writing.
Boron sheet and extra polyethylene were placed back on top. |

Fri Oct 14 13:32:52 2016, NT BREWER, S Go, JM Allmond, Ge preamp power loss and solution.
|
As previously recorded (81), on Thur Oct 13th, A NIM crate failure caused preamp power loss to the HPGe's. While D4 recovered with nominally the
same resolution as before. G7 would not recieve power to the preamps without an alarm from the NIM crate.
It was determined that there was a short along the lines of +12V and Ground , -12V and Ground, and between +-12V. |

Sat Nov 5 03:18:13 2016, SG BCR RCF NTB, Gamma peaks in the overnight run, related to neutron inelastic scattering
|
We looked at the overnight background run (161105_0935_BackgroundOvernight.root), There are gamma-peaks that could be related to neutron inerastic
scattering. We identified 565, 596, 608 and 69 keV. They might be related to the effect of neutrons. If this is the correct assignment, this would mean
at least some of the neutrons are not thermal when they interact with the germanium. |

Wed Oct 25 19:14:09 2017, NB, First pass efficiency for current experiment
|
I roughly (~10%) checked the efficiency for 4 of the peaks from 171025_1222_1355_152EuCloverCal.root.
I checked the peaks at 122, 245, 344, and 1408. The indication is an efficiency of 6.9, 9, 9,8, and 2.6 % for these gamma rays
repectively. |
