Description
Update on the progress of the Study, Integration and Implementation of the new RC6 beam line towards PUMA
Notes meeting 12/03/2025:
- Full line by end 25 with first transport test and first beam to PUMA.
- Question: run on local ion source in 2026? Power, vacuum, controls, consignation? Check with Jose for vacuum. Power?
Mark:
- Mark: PUMA status explanation.
Oliver: transport end of the year?
Jose: realistic? Already lifting and craning.. Mark: Lifetime important.. – next meeting in summer for response.
Lucas: taking first pbars unknown – personal PUMA issue. Outcome this summer. (HELENA stop 1st week December)
- Focus on getting RC6 ready! Disconnected from the PUMA status.
Pablo:
- RC6 beamline layout fixed.
- Additional irises (before and after switchyard)
- ZQNA production – 4 spares. Very reliable. New spare production postponed, new application on top of the AD complex. Spares are covering all machines.
- Layout naming MIRACLS device.. Proposal one line (Paul Trap to MR-ToF in sequence) – post processing needed to simulate anyway.
- Simon will take care of the naming
Jose:
- Vacuum status
- Line layout and vacuum distribution: OK keep as planned
- Ion source discussion – simulations needed ? Propagation to understand and make sure compatibility
- 169k on pumps
- 16k material
- 40k chambers
- 83k controls
- Total lower than first estimated
- Installation planning (end 25?)
- Define position primary pumps and if at HT or GND potential.
- Vacuum signals from HT platform.
- To all: Vacuum signals for users? – contact Jose/Abel (BI, etc.)
Oliver for Nicolas Critin:
- On layout: Cable trays, racks and HV cage etc. being integrated (Vincent)
- Mechanical designs and drawings almost all completed (see slide)
- Kicker: Lukas following up (electrical feedthrough RBS, etc.) – for kicker launch of chamber = vacuum (done) kicker plates to be launched – Oliver/Lukas o check.
Miguel Nieto:
- Status of BI equipment
- All on schedule
- HV cage collector plates ready for next year (2 long, 2 short) – not for first run (not needed)
- All designs finished. Delivery end of September. Procurement finalized end of this month.
- 80% at cern, rest outsourced.
- Assembly ~1.5 month for each DBox.
- Dry run using HIE components
- Installation: Rack in place, cable trays concept done (design)
- Cabling when HV cage in place and cable trays in place
- Electronics in production.
- TDCs received
- Mid November best case delivery of BI instruments
- Budget 350k mech + 75k collector plates. Electronics 65k +20k + 18k various elements
- Ask management (group level) if delivery needs to be earlier (sept components – nov ready)
- Stage DB3 (lowest priority) – first the rest
- Vacuum/Jose: don’t open each time – bake-out! Organize group everything.
- Software and FESA class needs discussion (next meeting?)
- Calibration – takes 1 extra month. Which precision? Dedicated meeting needed.
- HV cage MagneToF maintenance?
- Federico: split commissioning of the line? Jose: without bake out to gain time – if not needed for first tests..
- Erwin: cabling – attention: consignation during the year with HIE is an issue..
- Vincent: fixation cable trays on beams, etc. make HV cage all the way up to ceiling? Oliver: design for HV cage to finish which will define trays.
- Oliver: support positions to be marked drilled – defines cable positions
Roberto:
- Handling status
- Crane modifications done
- Modification brackets – CV ducts entrance ISOLDE
- Define ISOLDE lifting beam
- Oliver: prepare the spot for the generator – SCE Christoph to see who can do this. Patrick Gallay for connect up to mains – without power cut in 199?
Lukas:
- Status of optics and elements
- Layout frozen – however, final stretch might be shorter: advantage for the annex frame to stay connected to the PUMA frame
- Status of elements. UHV Quads difficult to (re)assemble (broken feedthroughs)
- Supports: MR-ToF and Paul Trap alu pieces: some existing, other parts being launched (drawings released)
- Beam switching tests ongoing at offline (special hardware developed for CAO switching?)
- HV cage concept and internal connections inside (use of plastic pipes internally for different potentials)
- Reporting on successful spectroscopy campaign at MIRACLS (34Mg at 10.5keV)
- Modifications needed for Paul Trap and MR-ToF – Oliver: test modifications on the LA2 position? Lukas: will need collaboration and might cause delay to move to the RC6 line. Alternative: install at RC6 and then modifications.
- Schedule: Oliver: run of MIRACLS at LA2 for physics interferes with installation at RC6? Lukas: will be in summer – enough time left to move to RC6. But ISO schedule not out yet..
- How to deal with commissioning of the RC6 line if parts are not in place yet? Timeline: Oliver: perhaps first test without bakeout. get optics ok to send beam straight through. – already challenge for this year. Separate parts and complete next year installation.
- Magda: manpower for move of MIRACLS? STI and EP together..
- Oliver/Lukas: knowhow MIRACLS. not many left..
Oliver/Alex/Survey:
- Floor points done and measured
- Mark different supports positions – to be scheduled – Alex: to discuss with Vincent.
- Vincent: work backwards: with elements on the supports and see where the positions of the holes for the supports come.. Vincent has all detailed drawings to derive first spots from.
Nicolas:
- Power convertors: ISEGG set of complete sets coming soon.
- Also HT equipment – next week coming – Lukas: install already when available? Also racks on the ground (to be fixed on floor).
- Vincent: from 3D drawing is accurate enough. – can do marking. HV and other EPC racks (in cage).
- New crates to design for PLC units
Controls:
- White Rabbit based – to be ready for this summer
- HW side: fibers requested to EN/EL (to see with fibers guys – did they pull already? Into BI rack)
Oliver:
- follow-up meeting in summer.
- With hopefully parts in pace
- Local ion source – could work since all other facilities are still running (controls etc.)
- Federico: strategy for BI. See how realistic is to put high priority to production.
Vincent:
- Paulo BI: crane in place? Manual crane? Chevre – see with transport but take in account to enter the HV cage, etc.
