Mon Mar 23 03:53:41 2020, Shahab, Runs, Reduced intensity inspite of faulty kicker,
|
SIS Kicker is still faulty. but we managed to reduce again the intensity to around 2e6 particles in ring to reduce scattering on scraper. |
Sat Mar 21 17:34:10 2020, Sergiy, General, Recoils,
|
We started recording the data from the recoils using the MCP from Pierre-Michael's experiment.
17:30 File opened: recoils1662.lmd.

Sat Mar 21 13:44:16 2020, Pierre-Michel, Detectors, Recoil detector,
|
We turn on Recoil detector, to use it as a monitor for target overlap.
MCP front -2500 V for highest signal rate.

All quadrupoles went off, waiting for the on-call service |
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".

Mon Mar 23 06:20:06 2020, Shahab, Runs, Position on scintillator corrected sitll no beam in ESR,
|
position on the scintillator was corrected by the OPs to center, but beam is still not in ESR. |

Thu May 27 08:26:15 2021, Yuri, Beatriz, General, Optimisation beam position on target and scraper position, 2021
|
Optimised overlap with the target by shifting the beam from -11.5 to 12.8 mm. This lead to an increase of the DSSSD rate of a factor between 2.5 or 3.
Adjusted scraper position by looking at x-ray rate and move it from +1 to +2. |
Tue May 25 13:49:51 2021, Oliver, Diego, Jan, General, No Beam, 2021
|
No beam from 13:49:00 until |
Sat May 29 23:05:52 2021, Oliver, Diego, General, No Beam, 2021
|
Due to a radioprotection issue in CaveA there is no beam. We wait for the radioprotection shift to arrive...
Beam back at 23:18 |

Sat Mar 21 11:30:04 2020, Laszlo, General, MWPC movement,
|
now we try to move the capture detector (MWPC in the 1. dipol before our Si setup) inside the ring while the DAQ was ON
we tried to move it as close as possible to the beam

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
|
Sat Mar 21 13:37:53 2020, Laszlo, , MCP can monitor target,
|
now with the MCP we can see clearly the effect of the target :) (scintillation?)
so we want to scan through the target thickness with the beam and choose the best position afterwards.
