Sat Apr 1 00:04:10 2017, 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

Preamplifier of crystal G7Red was replaced.
Output signals from G7Red are weird.

| The polyethelene arrived at RIKEN. Except 4 neighboring holes (located at the inner ring) the alignment is OK. |

Sat Apr 25 08:25:42 2015, 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 |

Mon Apr 27 04:40:43 2015, 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. |

|
| The activity of the 252Cf source, used for the calibration was 3.7 MBq at 15.05.2006. Unfortunately, uncertainty is missing from the data sheet :-( |

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
