Sometimes we see a broad sideband at lesser schottky frequencies to the high intensity thorium beam.
Pic 1 shows the relative broad sideband on the left.

All the beam settings will be given in a separate post.
We have 238U92+ centered in the ring with typically a few times 10⁷ ions.

Scraper positions where there is only primary beam for detector tests. Use only one outer and one inner scraper at the same time.

Runs of the night shift 16.04. after changing the wavelength range. The new range is 320.12 - 319.859 nm. The step size was decreased from 0.002 nm to 0.001
nm.
The goal was to have the same number of scans as before (261), however, the scan range in the labview program could not be set accordingly. We decided |

The ring SIS/ESR were set up for 229/89+. Pölease note that this not only 1e- Th but ponteially also the isobars of Ac (0e-1)/Pa(2e-, strongest) and U(3e-).
SIS eenrgy plus 3.5 MeV/u w.r.t. to the 238U92+ settings. We nearly don't see any of the primary beam in the ring
Cooling energy is 208998 KeV (read from the ESR multimeter).

After fixing the broken water connector in the laser head a new water leak appeared in the Quanta-Ray power supply.
We found the leak in the water pump flow line (arrow up). We took the water connectors appart, rebuilt the teflon seeling and put the water connectors |

Fri Apr 8 03:54:39 2022, Patrick, Laser, Q-switch window
|
The solution of increasing the Q-switch window from 2us to 5us described in [I]ID:148[/I] fulfills its purpose, but the window is unstable.
We saw the laser jumping across the screen which was because the Laser had a lot of hickups.
The hickups come from the signal which determines the duration of the window.
