Fri Jun 5 14:06:15 2020, Laszlo, Detectors, DSSSD and SCRAPER position estimate for Xe and Te experiments, 2020
|
We don't know the exact absolute positions of the detector (+scraper) and the beam. However, what we have to know is only these two relative positions respect
to each other. To get this distance I use two methods:
1, combining the infos from the set position during the beamtime + the measured pg peak position on the detector. The pg peak position is defined only |

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. |

Wed Feb 6 10:16:09 2019, Laszlo Varga, General, Study on scraping,
|
A publication on scraping systems suggested by Siegbert.
In the study they have used cylindrical "high-quality" slits. "High-quality" stands for well polished surface
with surface roughness <50nm. The material of the slit is Tungsten Carbide. |

It shall be used with the user <litv-exp>
