Wed Feb 6 10:04:23 2019, Laszlo Varga, Simulations, Background subtraction for 124Xe, 109In, 73As made by MOCADI,
|
General remarks to the MOCADI simulations:
scraper size vertically > (p,g) spot at the scraping position --> (p,g) can be separated
by truncating the
backscattered Rutherford events in the energy.
replacing the atomic masses to nuclear masses does not change significantly the absolute positions of the
(p,g) and the Rutherford. |

| BaF2 detectors are deactivated nor for the following runs. |

Tue Feb 11 13:20:01 2020, Jan, Detectors, BaF2 - HV settings,
|
| with these HV values the 6 channels are roughly gain matched, such that the 7.83 MeV Po-decay is around channel 5000. |
|
Fri Mar 20 16:54:53 2020, Jan, DAQ, BaF OFF downscaled red=32,
|
I introduced a downscaling by a factor of 2^5=32 for the BaF2 during target OFF.
The reason is, that we get a lot reasonable x-ray counts (K-alpha, K-REC) outside target ON phase.
So i want to minimize our deadtime during target OFF, to be able to use the data efficiently if needed.
