|
Comparison strip 6 amplitude spectra anew (red) vs (old) processing (Screenshot). Slight shift in amplitude and slightly less counts with new processing
in t+alpha peaks (1% level). This could be either due to less noise background, shift in neutron energy calibration (amplitude spectra shown with a cut
of 100 keV). pdf plot shows new vs old for neutron energy vs counts. only minor differences at low neutron energy, new processing makes spectra cleaner |

Tue Sep 9 13:59:29 2025, Selin, UserInputs for Processing
|
This is the UserINputs for the processing of Ca41. The dead time used for the processing has been 2us. Further processing of a B run with dead time set
to 0 (as seen in the inputs) showed that the dead time should be around 1 us. |

Mon Aug 25 10:47:44 2025, Selin, Pulser Test - Week 1 and 2
|
This is the pulser test between runs 221376 and 221377 (06/08/2025) which is in pink and 221439 and 221440 (13/08/2025) which is in cyan.
The back strips seem to be affected by gain as the pulser amplitudes are shifted. |

Thu Aug 21 16:19:43 2025, Emmanuel, Checking DEED 11 with the Pulser
|
We checked DEED 11 with the Pulser and it was still unresponsive (See screenshot).
Next, we will change the LEMO cables and do another Pulser Test. |

Mon Aug 18 09:19:27 2025, Emmanuel, DEED 11 NO Gamma Flash Signal
|
We observed that DEED11 no longer have Gamma flash signals.
Before the drop, it had some weird flunctuations.
Attached are the plots. |

Wed Aug 6 11:20:52 2025, Selin, Pulser Test
|
The pulser test was performed with a frequency of 500 Hz and with voltage settings of: 2V, 1.6V, 1.2V, 0.8V, 0.6V, 0.4V, 0.3V, 0.2V, 0.1V, 0.05V, 0.025V.
The run was started with calibration settings and then the voltage was changed every 2.5-3 minutes.
From the attached plots, it can be seen that everything is as expected. This means that the pulser multipolarity is consistent with front and |

These are the consistency checks done for Boron-3 sample.
Please note that the back strips for the first run are mismatched due to the settings in DAQ. |

Wed Jul 16 11:45:39 2025, Selin, Boron Spectra Update After Setting Change + Pulser Removed
|
Uncalibrated amplitude spectra of Boron (run221188) after the settings were changed, the pulser was removed, and the threshold in the UserInput has been
lowered. Both alphas can be seen in the front and back strips. The ratios between the alphas are similar for front (0.066) and back (0.063) strips.

|
I'm attaching a report for the experimental setup so far.
There is a main problem which haven't been solved yet and I don't know if that can cause problem in the future analysis.
Channels #23, #24, #31 and #32 are not working well. The signal os these channels look attenuated from the pulser, make impossible to see |
