To protect HPGe and 3He tubes from high intentsity primary beam, HV of these detector are off and the HPGe will be dismounted.

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.

2. Go to the directory : /home/pixie16/DAQ_1/include and open the config file : hvmon.conf

When you want to start HVs, you may have to change the last bit to be 1.

Then go to the following path /home/pixie16//DAQ_1/hv-mpod and execute the command ./hvmon (The process should start),

When you want to down HVs, you may have to change the last bit to be 1.

Sometime you may get error messages colored red on the status monitor when you down the HVs, then you have to change the config file (hvmon.conf) and set the last bit to be 10 to clear the error messages.

The IP adress of the computer is currently 192.168.13.250. The user name : pixie16, password: ask Nathan or Shintaro

For now, slot names PA should be He3 and DXX and GXX should be clovers.

You can also change the HV values by changing hvmon.conf

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.

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.

After removing the Red preamp ribbon cable, the remaining channels (K,G,B) were able to be powered on and found to have a nice resolution of near ~2.3 keV for 661 (137Cs).

During the course of testing, the preamp power distribution box (supplied from ORNL) was seen to have a fault in the +12V light and supply. This was seen by placing this supply in a new NIM bin and seeing that it would also not properly supply preamp power to clover D4 (which had recovered fully).

The consistency in this fault is seen as cause to be suspicious of this preamp power supply. It has been replaced by putting two ORTEC TSA's into a seperate NIM bin and using the standard power supply for D4 and G7.

There was no appreciable effect on noise in any other detector.

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. 

There was also significant drift in the Ge gain (seen on the pulser) this may effect the shape of these peaks. 

Some gain drift was also seen on He preamps during this run. The cause is yet to be determined. It is also yet to be determined if these gain shifts are correlated.

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.

Previously the efficiency was 11.1, 7.1, 5.3, and 1.6% . This indicates a reduction in efficiency below ~200 keV (because of YSO) and otherwise there is an increase in efficiency from 40% at 245 keV and up to 65% at 1480 keV.

A more complete analysis will come later.
