Tue Apr 8 09:28:49 2025, Team PLEIADES, General, Controlled access to ESR to connect cables for DAQ
|
We will need to enter the ESR to connect the cables again for our DAQ and then drive in the outside detector for 20min to get some data.
9:35 entered
9:41 exit
9:44 ESR available again |

Tue Apr 8 23:08:15 2025, Sergey Litvinov, Xinliang Yan, General, Tuning of the ion optics
|
From roughly 10:45 pm to 11:05 pm, Sergey tuned the
ion optics of the ESR to see if the mass resolution at
413.55735 MHz improves or not. Please note that the
frequencies of ions during the tuning process are not
stable.
Q-magnets and S-magnets have been adjusted, see
accelerator E-logs ID-844 titled ‘ ESR seting for
204Pt77+’ created by Sergey. |

Wed Apr 9 00:08:30 2025, Sergey, Yuri and Xinliang, General, Move of the scraper positions at ESR
|
From roughly … to 0:05AM, Sergey moved GEEXDS1HA (not
changed
in the end) and GE01DS3HG (changed from -85 to -80 mm) to reduce
the acceptance of the ESR to improve the mass resolution.
After the change, there are less small traces appearing in the
413.55735 MHz +/-5 kHz range.
The final positions of the two scrapers are
GEEXDS1HA :-10 mm; GE01DS3HG:-80 mm. |
