Wed Jun 5 11:29:13 2019, Jan, Detectors, position/channel calib.,
|
This is the first position calibration done with the detector installed in the holder. The goal is to assign rough positions (top/bottom/left/right) to
PreAmp- and Shaper-channels.

Fri Jun 7 14:39:36 2019, Jan, Detectors, Pt100 installation & readout,
|
The new detector holder incorporates a Pt100 temperature sensor, which is UHV compatible. The Pt-resistor is read out via 4 wires. These wires are integrated
into the D-SUB connector of the detector. The new wires use the pins as shown in the attached picture
"det_connector.png".

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

Mon Jul 8 14:57:07 2019, Yuanming Xing, Detectors, The measurement of the tilting angle,
|
As shown in the figure, the detector is tilted by a certain angle which is about 45 degree.
The tilted angle is defined as angle B.
We measured angle A using the vertical laser line (red) and papers with a straight line edge. So we can marked

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:

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

Thu Aug 29 10:02:22 2019, Jan, Detectors, bakeout at ESR setup,
|
The bakeout for our detector setup has started on the evening of 27.08.2019
We have a temperature sensor in the vacuum next to the detector.
The goal is to maximize bakeout temperature, while not going above 125°C at the detector/sensor.

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
