CLW, EO | New processing |
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 at higher energy.
Shape of the Li 240 keV resonance is shifted in new processing - either due to different offset in tof-ene calibration, or time stamp for signals in one of the processing versions is wrong. Need a new comparison to simulated spectra. |

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. |

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. |

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 back strips, pulser signals are more frequent and the pulser amplitude decreases with decreasing V.
The front and back pulser tests have been done with separate runs and the settings have been reverted to their original values (100 Hz, 2V, pulser is off). |

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.

Francisco García Infantes | Report Experimental SetUp Ca41 |
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 then in the Boron run.
As these channels are in the back side of the detector, it could be possible to run like? Unless we have more ideas about to solve the problem.
The front channels work well all of them, and the rest of the back channels work well as well.
I attach the current for the +15 and -15 volt applied to the PreAmp (low voltage) and the leakage current from the detector is 0.1 uA. |

TD | Silena 7710 Quad Bias Supply manual and internal configuration |
Manual - see attachment 1
Internal configuration
Voltage full scale - 400V/10uA
JP1/1-4 fitted
JP4 fitted *see note below
DVM card JP1 AB
HV jumpers AB
Current readout resolution - 10nA
DVM card JP2 LM
JP5/1-5 GH
Polarity - channels 1-4 negative
Note with channel 1 voltage set to -180V the output voltage measured by DMM is -40V.
The output impedance of the Silena 7710 outputs may be comparable to the input impedance of the DMM (DMM typically c. 20-40M) so the measured voltage will be a *lower*
limit.
With JP4 removed (per manual instructions for voltage full scale 400V/10uA) the front panel reads -20V with an output voltage measured by DMM of -40V.
Again, the measured voltage will be a lower limit.
By observation of the behaviour of the electronic noise of p+n junction and n+n Ohmic strips as a function of bias for MSL type W1 DSSSD 3353-4 (75um) the voltage
applied to the DSSSD is > depletion.
MSL QA tests report depletion voltage 28V and test/operating voltage 28+10V = 38V. |

CLW | expected counts B and Li |
The rootfiles countsB.root and countsLi.root contain histograms of count spectra that would be expected at n_TOF for a 10B and a 6Li target, respectively. The units in y are arbitrary. This can be used to check, if we can reproduce the expected trend with our Li and B measurements. So the histograms called "counts" can be directly compared to the histograms called "energy" in Sili_deed.c (they should have the same binning). You need to scale the histogram to get a decent overlap. You can use this also to estimate the neutron energy calibration - the thermal bump at low energy will give you a good idea of the flight path length. Structure at high energy will give you a better idea on the offset.
The files 6Li_endf.root and 10B_endf.root are the original cross section files, and countrate_calc.C is the file used to produce the count spectra.

TD | 34-way IDC to 37-way D connector ribbon cables |
The 2x sets of 34-way IDC to 37-way D connctor ribbon cables used at GSI for the two-alpha decay measurement have been located - see attachments 1-4.
They have been packed for shipment to CERN and delivered to stores for shipment. Awaiting quotation and P&M PO. |

Nick | 40K Borrowed Items |
We borrowed from n_TOF:
1x O-ring for circular side-flanges on the chamber (the borrowed part has a small green marker cross on it)
10x LIMO-to-BNC connectors (BNC female) from electronics lab outside EAR1 |
