Thu Jul 27 11:25:35 2023, Claudia, Al-26 planning meeting summary
|
Start 9th August, access to EAR-2 11 am earliest but can start in rack area before
Setup to be used: 1 dE (16 strips, 20 um thickness)
+ 1 E (16x16 strips, 150 um thickness. We have a spare for each thickness
Sample and detectors to be mounted on the same flange
Things

Thu Sep 18 14:11:29 2025, 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 |

Thu Aug 10 10:05:48 2023, CLW, Gafchromics Foil
|
Gafchromics foil was mounted on empty brass frame back to back with Li sample
Neutron beam goes well through the sample. Centered ~1 cm from sample center. Conclusion: no changes needed (too risky to make it worse and it
is ok now) |

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 |
