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.
