 Tue May 4 17:54:08 2021, Helmut Weick, Simulations, updated LISE file 
|
This file really has the optics like used in the last ESR experiments.
Now the transmission is also a little bit better. |

Sun May 9 21:29:26 2021, Helmut, Wolfram, Yuri, Accelerator, target TE3UF shift
|
We see a very strong line at the left end of spectrum, stronger than all other lines.
When we shift the target TE3UF_H from -35mm to -37mm it gete weaker, but -37mm is the end of drive.
In the other direction it becomes worse. At -25mm completely new peaks.

At the moment we see a second peak to the left of each intense line.
The distance between the main peak and the shadow is roughly the same for each peak.
This hints to a sharp fall in the isochronicity curve.

at 17:20 intensity was suddenly reduced.
Operators checked. Intensity was a bit low and fluctuating for a while (8e8 to 1e9)
Intensity (1.5e9) was recovered at 18:16 |

Sat May 8 21:10:24 2021, Michael, Ruijiu, Helmut, Yuri, Wolfram, Sergey, Shahab, Runs, started data taking with high resolution

after optimizing the scrapers we have reached the highest possible resolution in the isochronous mode.
starting data taking with this new settings.

|
After setting up on 70Se
Sextupoles were adjusted to optimize the resolution of the 70Se peak. Set values are in the ESR logbook.
The SIS energy was shifted up to increase the number of 70Se.
