David, Liliana | General | Ion source change |
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. |

David, Liliana | General | Beam intensity |
From 4:05 to 4:15 beam intensity was 1/2 as before. |

Jan, Akash | Accelerator | Beam intensity |
Intensity went up from 5e8 to 1e9 extracted particles from SIS. |

Yury, Helmut | Accelerator | added high Brho scrapers |
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. |

Andrew Nic | Runs | Frequency shift |
The freqency suddenly shifted at time 16:11:47 and remained shifted until now
The ESR status in the monitor stayed blue. No obvious sign that a magnet was down. The operators are checking
Sergey telephoned, he is also not sure but suggests stopping starting the ESR. We will wait for Yuri |
