we run at MAX INTENSITY as we can: SIS was increased to its top, but unfortunately we still end up with 1.5e9 at injection from SIS. Sergey also optimized some stuff.

purpose: data with TARGET ON and SCRAPER OFF --> this leakage current spikes associated with primary scattering from the scraper edge seem to disappear, but we get still 10kHz rate on the detector a few sec after injection(this small "bump" 
after the peak in the Si current - see the picture below)

Yuri and ESR team are optimising 
the deceleration in ESR.
DSSSD detector is taken out at 
10:55 am.

The HV for DSSD is switched off at 
11:10 am as the detector was out 
and the leak current was ~18 uA.
At 11:11 am, the file was closed.
File close: run050 stopped.

update by Laszlo: the increase of the leakage current is due to the fact that we have a vacuum measurement device next to the DSSSD when it is moved out. The phenomena is normal, the DSSSD is hit by electrons (or ions) coming from the vacuum measurement device.
