Today, until 11 am, data were taken for the 188Hf setting. Since then, we are now tuning on the 192Pb82+.

ESR setting is changed from 188Hf72+ to 186Hf72+. SIS-18 beam energy for 
this fragment is 510 MeV/u.Brho = 7.86166 Tm.

ESR setting is changed from 188Hf72+ to 186Hf72+. SIS-18 beam energy for the primary beam transmission check is 528 MeV/u.

Electron cooler anode voltage needs a repair which might take 20-30 mins. If it takes longer, we'll proceed without a cooler curve measurement. 

No additional HV. So, have to proceed without the cooler. 
Spare Power supply did not work either, we will not be able to use the cooler for the rest of the experiment

Regina, Jan, and Markus are in the ESR to check the electron cooler.

NTCAP restarted 17:43

we have 63% full on bank 2 of the NAS
which means about 11% every day
this gives us roughly another 3 days of recording time
we can always switch to bank 1, but changing that, needs changing the analysis paths. so for now, we continue on bank2

:-)

We have not seen 184Hf and 186Hf so far. 

NTCAP and analysers are stopped at 17:00.Iris goes inside to move the detectors 

New settings for resonators:

410: plunger stay the same

245: plunger now at 150

From 14:15, we have every injection to the ESR. FRS is on pause for 1-2 hours.
