CJ Griffin, M Cockshutt, G Leckenby | General | Moving PLEIADES detectors in |
The inner PLEIADES is moved into position close to the beam.
Device control for the outside pocket is not currently working so that pocket remains in its outward position.
NTCAP/Schottky data acquisition stopped during pocket position tests.
Inner detector (x86l-124 BGO)
Device: GE01DD2IG
Position: +20 mm
Scraping beam: not possible
Outer detector (x86l-131 GAGG)
Device: GE01DD2AG
Position: -127 mm

PLEIADES shift instructions available at:

Leakage current tracking:

Leakage currents should be documented every ~1-2 hours while the detectors are biased. |

Ruijiu Chen，Wolfram | Analysis | Good injection ratio |
Currently, we only use 37% of the injections in our data analysis. However, 63% of the injections have a height below 100, and these may include
single ion injections. We need to visually inspect these injections to identify the single ion injections. |

All | Accelerator | Stop 194Pb, switch to 208Pb82+ |
The repair of SIS electron cooler power supplies
In the meantime we received a few injections and confirmed that 194Pb setting is still as it was before entering into the ESR
Now we change to 208Pb82+ to do several ESR accelerator tests
Esis = 517 MeV/u
Change the beamline to 208 Pb 82+ and the ESR to 208 b 82+ and NO other changes |

Zac, Johan | General | Beam lost at 06:27, returned at 06:34 |
Spike in beam intensity at 06:27 (5x usual intensity) and then beam is lost. HKR says it's a problem with the magnet's power supply. Once the beam returned, the peaks are shifted to the left but are slowly shifting back into position. |
