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 1^st week December)

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.
