 Sat May 17 21:27:17 2025, Wilfried, Rodolfo, Laser, Scraping the laser beam 
|
The beam stabilization in not working properly. So we have turned it off. We also scraped the laser beam at the E-Cooler and bring the laser beam to the
right position.

|
The attachment shows the signal of the particle detector for bunched beam (red, files 104-112) coasting beam (black, files 113-117) as a function of the
time for one cycle of the DRALS pattern. One can identify modulations of the signal during the cooling step in both traces. However, there are some clear
differences:

Sun May 18 02:24:46 2025, Wilfried, Rodolfo, Carsten, Detectors, Antrieb Cu-Mirror defekt
|
On Saturday afternoon we moved the Cu mirror to the inner position, however an issue appeared when we tried to move the mirror to the "park" position. The
stepping motor did not react properly, it clamped. After restarting the software we could actually move the mirror out, but the stepping motor as well
as driving system made a lot of noise until the parking position was reached. This issue has to be investigated specialists after the beamtime. |

|
We changed the position of the laser back to the position which was set up in [COLOR=blue][B][URL=https://elog.gsi.de/esr/E0038/85]E 85[/URL][/B][/COLOR]
by changing the motor position of motor 4 in the kangoo software at ATPPC031 from -0.1 to -0.3. |

Tue May 27 10:56:44 2025, Konstantin, DAQ, Common stop
|
The common stop was wired through a 1:2, and subsequently through a 1:99 rate divider channel. However, since the pulse width was too long, the 1:2 channel
was translated into a 1:4 reduction. This must be considered, when the data is processed via go4. The reduction factor in the SetParameters.C file must
be set to 198 accordingly. |
