Zn run
isotopes run: 74,76,78Zn run, charge states: 74Zn20+,76Zn20+,78Zn21+

breeding time: 78 ms

efficiencies: 2-3% EBIS; 50% trap; 70% Linac

currents after trap and ebis: ??? à beam detection will work up to 80Zn

technical problems: running GPS at 30 kV, complete re-setup of REX for this voltage

comments: used 39 K for setting up the low energy part

used 66Zn for testing (not stable since it's laser ionised)

lesson: a well outgassed produces very little beam, mass marker important
don't mess around / tune a REX system setup with high intensity beam
