e748 | RUN | General | CD2 | RUN 374 |
We stopped run 373 to check the MUVI scalers on the DAS.
We wrote the parameters onto the CHIO digitizer and restarted -> Run 374
Same conditions as before.

We note that although the 18O intensity is the same, the counting rates in CATS1, CATS2, CHIO and Plastic have decreased by 13 % since the beginning of run 374.

e748 | BEAM | General | CD2 | Beam position on target |
| The beam spot on target has shifted upwards by ~3 mm since beginning of 10Be run (see run 366 and attached plot from run 374, July 8 20:48). |

e748 | BEAM | General | CD2 | Update: beam position on target |
At ~21:00 we called PCP: They adjusted the DC41VE steerer to center vertically the beam on our target.
See attached plot.
This has no impact on the counting rates in our detectors.

e748 | BEAM | General | CD2 | Scalers run 374 |
Counting rates keep decreasing though the primary is still ~4.5 uAe and the beam is centered on our target.
We called François de Oliveira who helped us to print the parameters of the line. We go to the PCP with the print. |

e748 | OFFLINE | General | CD2 | Elastic scattering MM6&7 |
Telescope 6&7 are analyzed for 12Be beam.
The energy of Si vs angle plot for each telescope (CsI veto and beam position gate) are shown.
The red lines are kinematics for 12Be(d,d) and (p,p).
Two loci seem to correspond to each elastic scattering. |

Vaccuum was lost after CSS2, so we lost the primary beam (18:30)
Operators called the astreinte. |

There is a major shutdown of the GANIL phone system.
You can not call the pcp via the usual extention; instead call : 02 31 43 59 77

All god beside that. Still no phone on campus! |
