Esther, Nikos | General | Brief beam interruptions |
There was no beam from SIS between about 06:28 and 06:39.
Again from 07:02 to 07:11.
And again from 07:49 to 07:55. |

Yuri | General | Slit changing |
I would like to close E01 slits a bit more and get 30 min of data with higher
resolving power.
EEX scraper from -10 now -1
E01 unchanged |

Yuri, Sergey, Nikos, Esther | General | Final Injection |
The a final injection from SIS18 stored at 10:04.
The scrapers were moved out before to get the maximum intensity.
NTCAP is still running, the RSAs recorded the last files at 10:04.
The plan is to keep running like this for about an hour. |

JG, ID, MC, CG | Detectors | pleiades in position |
The pleiades detectors are now moved into a position which does not disturb the stored beam.
inner detector: BGO
device: GE01DD2IG
position: +20mm
scraping beam: not possible
outer detector: GAGG
device: GE01DD2AG
position: -55mm
scraping beam at: -45mm
These positions are fixed, i.e. not moving automatically. |

Shahab | Detectors | 10GB cables for the DAQ rack |
We have been working together with IT on the speed of data transfer: with the new 10 GB interface we can now transfer data from NAS to Lustre with 400MB/s. From NAS to GPU Computer up to 700MB/s. All cables around the rack are now 10GB capable. |

Team PLEIADES (JG, ID, CJG, MC) | Detectors | Entering ESR for PLEIADES |
We are going to enter the ESR to check on the PLEIADES pocket detectors and install a nitrogen cooling. |

Team PLEIADES | Detectors | Inserting both PLEIADES detectors |
We are inserting both PLEIADES detectors step-wise, one by one. Main beam should not be affected too long. |

14:12 We are moving the inside pocket out for a moment, change the bias |

Team PLEIADES | Detectors | Moving detectors in again, to 20mm |
14:57 We are moving the inside pocket detector in again, this time to 20mm |

Team PLEIADES | Detectors | Outside pocket "repair" |
We tried to convince the outside pocket to move, no success. We can hear the "hissing sound" of the pressurized air but no movement. Sergey tried to move it from the HKR, also no success. After that I tried to move it again from the Messhuette...and the "Out of tolerance" error message is gone, and the pocket seems to move. (We cannot confirm from inside because the ESR is already closed).
Guess the outside pocket got intimidated by Sergey and decided to get moving again... ;-)
We will take a bit more beam once the setting is stable, but try not to fry another detector. |

Team PLEIADES | Detectors | Moving outside detector in |
17:35 Slowly moving PLEIADES outside detector (GE01DD2AG) in for some data. Clipping ions at -20mm. Leaving detector at -40mm for a few minutes. |

Team PLEIADES | Detectors | Outside detector moved out again |
19:20 The outside and inside PLEIADES detectors are both moved back into their parking positions. Shifts should continue monitoring the leakage current on the mesycontrol screens and enter the values every 2h in the Google spreadsheet:
