Tasks for cleaning 508

• Kitchen
  • Bring bottles, coffee capsules, … to recycle bins
  • Check cupboards for open/expired food
  • Remove everything which is not clearly labeled -> put on talbe
• Move electronics from Luis's office to 508 DAQ room -> need car
  • I have boxes which can be used
• 508 DAQ room
  • Remove broken chairs (also from visitors room and from little room next to kitchen))
  • Tidy up, put cables back in cabinet
  • Make sure that each computer has a screen, mouse, keyboard attached
  • Check if all computer has a label with name, label screen with same name for clarity
• Common safety shoes:
  • Organise shoes  cabinets per size
  • Number shoes per size (36.1, 36.2, 36.3) and make overview of number of shoes we have to put on the TWiki --> ask Hanne for markers
  • Label each shoe with ISOLDE --> ask Hanne for markers
• Clean underneath stairs
  • Broken equipment etc. to recuperation (-> transport request)
• Experiment DAQ rooms:
  • Not frequently used safety shoes to common pool (with agreement of owner -> reach out to owners if not done)
• Helmets:
  • Unpack helmets in 508 visitors room
  • Make transport request for helmets in bad state in 170 to recuperation - get RP checked
• Check Twiki and add/correct where necessary
  • Common equipment
  • Welcome document
• Return borrowed electronics to e-pool (green sticker)
  • Hanne has collected a few in the hall
• 508 Meeting room
  
  • Write instructions how to use your own computer (do not disconnect cables but make a zoom call and login from the videoconferencing computer, your laptop, potentially also from the projector computer). --> Or find alternative which works.
• Outside:
  • Check for equipment/pallets lying around -> make transport request
  • Broom to clean all the needles in the outside area between 508 and ISOLDE

End-of-the year checklist

• Gas bottles
  • Do you have gas bottles which should be returned? Procedure to return on: https://edms.cern.ch/ui/file/2278255/1/Procedure_BottleReturn.pdf
  • Check that the gas bottles you returned were actually picked up
• Chemicals
  • Everything up-to-date in CERES?
  • Dispose of chemical waste and chemical which won't be used for a long time
• SAS 
  • Were all transport requests which you made picked up?
  • Are there items/boxes which you don't know where to take them?
• Electronics:
  • Return electronics to the e-pool
• DAQ rooms:
  • Check that you don't use the cable trays as storage points
  • Tidy up, send items back to home institutes/waste 
• Kitchen:
  • Check cupboards/fridges for your food
    • Throw away expired food
    • Label
• ISOLDE hall
  • Are all cupboard, big equipment clearly labeled with an up-to-date contact
• Local team
  • Everyone on the right e-groups?
• Pressure devices:
  • Check that all dewars are in infor. Update description to something useful ("Miniball LN2 dewar - Apollo" instead of "ISOLDE mobile dewar")
  • Check that all safety valves and burst disks are linked to the dewar.
  • If you have safety valves/burst disk in a cupboard but not used, update status

Should we move from Twiki to confluence?

Pros of moving from TWiki to Confluence

• More modern and user friendly interface

• Easier editing, fewer formatting issues

• Better page organisation and navigation

• Clearer permissions and version history

• Easier for new people to learn

Cons of moving from TWiki to Confluence

• Migration effort, even if the content is limited

• Formatting will not transfer automatically, some pages need rebuilding

• Need to manage two systems during the transition

• Slight learning curve for those used to TWiki

• No added benefit from Atlassian integration since other tools are not used

---

Questions to ask before deciding

• How many pages need to be moved, and how much time will it take?

• Does the current TWiki cause problems that Confluence would solve?

• Will contributors find Confluence easier and maintain pages more regularly?

• Is Confluence widely accessible at CERN for everyone who needs it?

• Is there a long-term plan at CERN to favour one platform?

• Are we willing to maintain documentation more actively if moved?

14:30 → 15:15 ISOLDE seminar or Physics presentation by local group

Title: Deformation in A=144 isobars via Coulomb excitation using the Miniball array
Speaker: Josh Curry (University of Liverpool, UK)
Abstract: Safe Coulomb excitation measurements with Miniball in the IS708 experiment at ISOLDE were used to study predicted octupole deformation in neutron-rich ¹⁴⁴Ba, as well as other A=144 isobars that appeared as beam contaminants. Preliminary analysis shows population of several low-lying collective states - including new observations in ¹⁴⁴Cs. Extraction of E2 and E3 matrix elements using GOSIA will be performed to give a better understanding of the shapes and collectivity of these neutron rich nuclei.
