1. UNILAC running again, so we resumed the beam tuning wherre we stopped yesterday at 14:00

2. Goals: Reduce intensity and lifetime of "antibunch" contamination while maximising intensity for main bunch/on PD
   Adjusted bucketsize, el. cooler current, cooling times,.. 
   Managed to get bunch width to 6-8 bins and get 10k counts in 15 mins with only 20 injections
   but el. cooling still takes long and sometimes bunch phase jumps by 90° in "measurement manipulation"

4. Checked scan range again and found small discrepancy

3. Decided to switch el. cooler voltage (1st cooling) by +100V, 
   ion beam position in el. cooler should not be afected by this too much, at the scrapers at which the dispersion is maximal it shifted the beam by 5mm

new revolution frequency: 1.54315 GHz
new electron cooler voltage: 104506 V(+95 V; slightly adjusted to match revolution frequency   
"antibunch" vanishes within first 10s
bunch on PD wider, but might be missmatch of HF and cooler voltage
