ID GK DK Liu | 37Na or 36Ne labels? | The BigRIPS settings are all called "36Ne setting" but the night shift labels these runs in the BRIKEN DAQ as
"37Na". We are not sure why we label it with 37Na, we think this should be consistently named 36Ne like the
BigRIPS settings. (For sure the strongest component in the beam might be 37Na. In the 39Na settings before it
was 40Mg and we labelled it 40Mg...) |

G. Kiss, J. Agramunt | BRIKEN Test setup | Altogether 16 tubes are mounted for the parasitic detector test (see the attached photos):
- two tubes (belonging to RIKEN) are in a 10 cm x 10 cm x 30 cm polyethylene matrix inside Eurica, the distance from AIDA is about 30 cm
- 12 tubes (belonging to RIKEN) are in a 20 xm x 30 xm x 30 cm matrix, outside (below) Eurica, at the closest possible place to AIDA, the distance is about 60 cm
- further two tubes (ORNL) are at the bottom of the Eurica support, about 1.2 m from the AIDA Silicon.
Furthermore, spectra measured using a 252Cf source is attached to this report, too (Jap1Cf-RIKEN tube, Us1Cf-ORNL tube). At the moment a background measurement is running. |

G. Kiss, J. Agramunt | neutron background at Eurica | Based on an about 8h long background measurement, the neutron background at the Eurica site was found to be about 0.006 neutron / sec (in the Riken tubes) and 0.019 neutron / sec (in the ORNL tubes). The beam was OFF. |

DK | Applying Biases | Today, Gabor and I discussed with Nathan from ORNL about the biasing system used for Ge, 3He, Plastic, and others. Phong is also a bit familiar with the system (edit also
Shintaro
Go). While there
is supposed to be a manual, Gabor and I did not find it.
In case of trouble: contact Nathan Brewer Gmail: Brewer.nathant@gmail.com Skype: nathan.t.brewer
Log in to high voltage PC:
$ ssh -Y pixie16@10.32.6.161
passwd: ************
For HV readout, run firefox in the background
$ firefox &
You can probably check the history or restore pages, but it should be pointed
at 192.168.13.239
It updates automatically every several seconds. Unless the HV monitor is
running, it may show nothing...
For temperatures:
$ cd ~/DAQ_1/kelvin
$ ./kelvin-read
(there are options to kill all temperatures)
For applying existing HVs (BE CAREFUL!)
$ cd ~/DAQ_1/hv-mpod
$ ./hvmon
If you want to change the voltages (up or down) kill this with Ctrl+C
To alter bias values or change which ones are on, you can edit the file:
$ ~/DAQ_1/include/hvmon.conf
Once the file is saved, restart hvmon.
We are running the above in a GNU screen session, with firefox on one computer. It has a note taped to it. Please don't use this computer for other purposes unless necessary!
Let me note that the PC we log in through has essentially no .screenrc file so you can barely understand you are actually using screen. If you are not very familiar with
screen, better not to touch it. I will put a better .screenrc later (but I also don't want to change the setup now).

All analog signals are seen in the oscilloscope with reasonable behavior
28 Mar 2017 15:56:03
Ramp up all Ge clovers.
D at 3000 V for all
G at 2500 V for all (except G7R is 3000)
28 Mar 2017 16:26:39
Biases are all applied (maybe several minutes earlier)
D4 temp 83.7 K
G7 temp 79.6 K
28 Mar 2017 17:51:09
Now we ramp up 3He and plastics. We keep the Ge on during this time.
D4 83.7 K
G7 79.6 K
Everything looks good! |
