Please note that the file started one minute earlier had wrong settings.

The measurement does not represent the later settings since here hte 229Th89+ is still on a too inner orbit (cf. previous post).

This is the first time with LV buffer problem solved (see Elog ID: 184). Before the PMT signals were out of sync with the wavelength data!
We concluded to scan with step sizes of 0.002nm, scan range of 0.5nm (f
nm), dwelltime = 150(5s), loops = 2 (approx.: 30min measurements).

Entry  Sat Apr 9 15:47:21 2022, Carsten, Rodolfo, Sarper, Patrick, Runs, Afternoon and night shift runs 
After the morning shift, we got new increment (nm) for the laser scanning. We are now scanning 2 nm of wavelength range in 5 big steps (5 x 0.4 nm). Started with 323.2 nm - 322.8 nm range. Every big step (0.4 nm) is scanned with 0.002 nm of wavelength increment.

Every scan takes ~ 18 min (0.4 nm range with 0.002 nm steps), we have scanned 2 loops. Total scanning time ~36 min.

Carsten (19:00h): I notized that a lot of beam gets lost when starting scraping. I called Sergey Litvinov to help me to introduce some additional cooling/waiting (10s) after the ramp and before scraping and bunching. It increased the number of ions available for the measurement roughly by a factor of 3-5.

Some runs have wrong WM data. Set Wavelength is good.

Following files are saved differently, the command missed the 229Th in the end (/data.local2/BeamTimeTh22/229Thor -auto -rfio)

We scan the wavelength scan range is 322.01 - 321.60 nm

before the first scan of the new wavelength range we changed the high voltage divider ratio in Labview from 248514 to 248517, which is the correct value for this voltage. This leads to slightly higher cooler voltages in the log.
