MW, KR | suspicious clover G7 temp sensor |
We observed 6 pm LN2 filling of both clovers on Monday Nov 5th.
D4 went full within reasonable time of below 10 minutes.
Filling of G7 was stopped by "emergency sensor" after about 15 minutes of filling.
Likely the temp sensor at the LN2 overflow pipe of G7 should be changed.
The clock at LN2 fill system is off by about 25 minutes (filling comes later than set at the control unit.)

"The clock at LN2 fill system is off by about 25 minutes (filling comes later than set at the control unit.)"
Yes, This is how it always was.
"Filling of G7 was stopped by "emergency sensor" after about 15 minutes of filling. Likely the temp sensor at the LN2 overflow pipe of G7 should be changed."
You can put this on a different line of the fill system.... |

Ale | spikes on some spectra |
Some spectra show spikes or do not look normal. This should be checked.
Look at BRIKEN, Ring4, Ring5, Ring6, Ring7, D4, G7, Clovers,
Rate1, Rate2, Rate3, etc.
Reset time stamp: 21.00, 8th-nov.
Probably there was a problem with the clock from AIDA related to the LN2 filling.
So to recover, we need to stop acq (only stop acquisition in DACQ control),
send to hard (send parameters again) and once all the parameters were sent,
Send Sync pulse. |

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. |

Phong, Liu J J | dE detector position and output signal from preamplifier |
dE detector is mounted onto the back side of the shielding (attached photo: dE_position.JPG)
The detector consists of 26 strips. In this setup, the detector is devided into 2 parts corresponding to 2 readout channels. Each part consists of 13 strips joint together.
Output signal from a high gain channel of preamplifier with 137Cs source is shown in attachment 137CsTest_ac.JPG.;
The white noise is about 2 mV for high gain mode.
We will switch to low gain mode during the experiment.
* note:there is a 200 mV offset due to the characteristic of the preamplifier (see attachment dc.JPG) |
