1. Comments and questions to last week’s minutes
   
   1. There were no comments.
   2. There was a question concerning the RABBIT irradiation: The RABBIT irradiation does not need shifts, since only protons are used and not the machine itself.

2. Main Technical News
   
   1. On HRS, the WITCH experiment finished last Wednesday morning.
   2. The emittance meter tests revealed that a factor of 3 less emittance was measured compared to the real expected beam emittance. This is due to the performance of the emittance meter at low beam intensities.
   3. On Thursday, the target was changed to a UCx-Re target # 492 wit RILIS laser ionization, which is being re-used. Setup and stable-beam tuning was performed also on Thursday, followed by the proton scan and start of COLLAPS experiment on Friday. COLLAPS used the ISCOOL in bunched mode and finished Tuesday. Now, SSP collections take place.
   4. On GPS, tests with HELICON target were continued. Thierry gave an overview: A few 1000/µC of ⁹CO⁺ were seen and thus this been can now be successfully provided at ISOLDE.
   5. On Monday, the target has been changed to the Ti-44 target (50 MBq, half-life of 60 yrs.) from PSI with a VADIS ion source. A first observed vacuum leak was due to a wrong coupling of the target and was remediated.
   6. The GPS robot still has problems, but this was its last use. For 2014, new robots will be installed.
   7. Christoph Seiffert is involved in the Ti-44 beam production within his PhD thesis, since the titanium will be provided as molecular beam.
   8. The beam is in REXTrap, however, it looks very large. This problem was already there with the HELICON ion source, which suggests that the extraction electrode is not properly in place.

3. Other Technical News:
   
   1. On HRS, scanner YHRS.SC483 is still not working properly. YHRS.FC490 reads less than YHRS.FC690.
   2. A power-supply mix up between LA1 and LA2 has been sorted out. The LA1 user vacuum gauge had a wrong read-out and had to be overwritten. Moving from GLM to LA1, the SSP experiment had a problem with a stepping-motor, which was finally overcome.

4. REX/RILIS:
   
   1. No news.

5. LS1 – December 2012 until April 2014:
   
   1. Erwin gave an overview of how the works within LS1 will affect the ISOLDE hall.
   2. People coming to ISOLDE should from 2013 on generally use the upper entrance to bldg. 170

6. Physics and Schedule:
   
   1. COLLAPS measured the hyperfine structure of ^51,53-64Mn and also ^58m,60m,62mMn. They will be able to extract spins, radii and moments.
   2. Beam was shared with Solid State Physics

7. Safety:
   
   1. RAMSES – Radiation Monitoring System for the Environment and Safety – will undergo a maintenance phase from 28.11. until 7.12. You might need to re-log in on the monitoring computers in the control room. Also, some alarms might go off within tests.
   2. If you hear an alarm, react as foreseen. In addition, contact operators to find out whether it was only a test.

8. AOB:
   
   1. It is being discussed to move the ISOLDE PGM to Thursdays, 14h00.
   2. ISOLDE will participate as usual in the CERN summer-student program.
   3. ISOLDE is currently paying 3600 CHF/month for rentals from the electronics pool. Jan Kurcewicz has made an inventory, which shows that about 60 devices can no longer be found.

Please check at your setups (especially travelling experiments) whether a device from the CERN electronics pool is in use. Contact Jan in case of questions. See also e-mail from Maria.

4. The seminar was followed by a presentation by Christoph Düllmann: “Superheavy research at GSI”. The slides can be found under the following link: https://indico.cern.ch/conferenceDisplay.py?confId=210988.
