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.
1- Uncalibrated amplitude spectra of strip 2. |

Sat Jul 12 10:30:06 2025, 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 |

Wed Feb 12 13:51:02 2025, CLW, expected counts B and Li 6x
|
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 |
