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. |

Tue Jun 25 21:19:50 2019, Laszlo, Simulations, MOCADI input parameters,
|
initial BEAM input parameters for MOCADI are based on:
- https://web-docs.gsi.de/~weick/mocadi/download/esr-exl-test.in --> twist parameters (ratio of X/A and B/Y)
- M. Steck et al, Electron cooling experiments at the ESR, NIM A 532 (2004) 357-365 --> epsilon_x = 5·10^-7

Fri Aug 9 13:14:09 2019, Laszlo, , pn channel simulations for 111Sn(p,g)112Sb experiment,
|
The p,n channel opening for the 111Sn+p reaction is at 5.8895 MeV/u beam energy. Therefore, when choosing as 6MeV/u, 7MeV/u, 8MeV/u beam energies, there
is not much kinetic energy left for the outgoing neutron --> there are "less" nuclear levels populated above groundstate in 111Sb, they can be handled
explicitly. My simulations are based on TALYS results. The following steps did I made:

Fri Aug 9 13:43:15 2019, Laszlo, Simulations, pn channel simulations for 111Sn(p,g)112Sb experiment, 12x
|
The p,n channel opening for 111Sn beam is at 5.8895 MeV/u beam energy. Therefore, when choosing 6MeV/u, 7MeV/u,
8MeV/u beam energies, there is not much kinetic energy left for the excitation of the 111Sb nucleus --> there
can be "less" nuclear levels populated above groundstate of 111Sb. These "less" states can be handled explicitly

Wed Sep 25 13:03:46 2019, Laszlo, Analysis, simulations on 118Te+p, 11x
|
I have made some simulations at 8AMeV, 7AMeV and 4AMeV energies for the main 118Te + p reaction channels. For the
Rutherford simulations credits to Yuanming! For each energy there are 3 simulations: without the scraper, with the
scraper (online), scraper (online) + E-truncation (offline). The scraper is treated as an "ideal scraper" meaning
