So far only scrapers for low Brho were used:
  GE01DS_HI = -58mm (arc from inside) and
  GEEXDS2HA = -11.2 (straight from outside)
We also want a cut on high Brho to avoid possible strange lines.

GE01DS_HA is limited in motion, at the maximum inside position (0.0 mm) there is no effect.

Next EEXDS1HG (aperture for ToF-detctor) in mm
120 -  completely out
 60 - no effect full beam
 45 -   "
 30 -   "
 20 -   "
 10 - very little beam remaining
  5 - gone
 12 - little beam
 14 - narow but little
 16 - narrow with small tail in left side
 20 - again like full
100 - full (as reference for the eye)

Then similar with E02DSHG in arc dipole in mm
 -130 - full
  -60 - full
  -40 - gone
  -45 - very tiny
  -55 - full
  -50 - less beam
  -52 - similar
  -53 - no difference
  -58 - looks like full

Now add EEXDS1HG again with -16mm, no difference, so keep both in.
==> we cut in arc from both sides and on straight secton from both sides
    Intensity does not look different to scrapers out. 
    It looks like a bit less 70Se in ESR then 1h before, but maybe other reason.

Intensity went up from 5e8 to 1e9 extracted particles from SIS.

From 4:05 to 4:15 beam intensity was 1/2 as before. 

Changing ion source, no beam expected for the next 30 minutes.

2:15--> Beam is back, intensity not as high as before but will increase in the next few minutes as the source gets hotter.

For few minutes (starting at 00:05) beam intensity went down. Same as it was reported by the previous shift. 
Until 00:27 beam had lower intensity than before (3e8) 
Now intensity is back to 5e8.

reference level=-20 dBm.

There was a disruption from the SIS side for a few minutes.

There is a drop in SIS intensity and the operators are informed.

SIS intensity is back

current scraper positions suggested by Sergey:

GEEXDS2HA = -11mm
GE01DS-H (innen) = -58mm

Data is being shared on the WWW server.
Time difference between the analyzers is in order of seconds:

time stamp of the 245MHz data is leading those of 410MHz by 21.733 [s]

Main user is finished. We started data taking again...

We just started data taking. But a few minutes later the main experiment needed to do some adjustements to the beam. This interrupts us for a couple of minutes...

After setting up on 70Se
Sextupoles were adjusted to optimize the resolution of the 70Se peak. Set values are in the ESR logbook.
The SIS energy was shifted up to increase the number of 70Se.
Esis original = 445.68 MeV/u
Esis now = 451.68 MeV/u (+6 MeV/u)

scrapers: 
GE01DS_HI =  -58mm
GE01DS_HA = +130mm (fully open)
GEEXDD2_S = -0.5mm
GEEXDS2HA = -11.2mm

This is the latest ID of 70Se setting.

turned on extra 20dB amplifier for the 245 Resonator around 12:32

1) Over night the source was conservated. It is being restarted now.
2) The approximated amount of Gas in this bottle shall allow for running until tomorrow morning (~24 h). There is still another bottle in reserve (1 l) and one reserve from GANIL (0.5 l).
3) Beam-time coordinator suggests to run until the gas is over, i.e., up into the weekend.
