508/1-001 (CERN)

Update on the progress of the Study, Integration and Implementation of the new RC6 beam line towards PUMA

10:00 → 10:10 WP1: Management and Coordination

Speakers: Erwin Siesling (CERN), Oliver Aberle (CERN)

Status_Update_PUMA_3_07_2025.pptx

• Successfully tested different components (vacuum, TPC, trap electrodes)
• Focus for next weeks: get beam permit, cooling magnet, take antiproton beam this summer
• Design for transfer beamline between RC6 and PUMA main frame finished (consists of pulsed drift tube, quadrupole lenses and Einzel lenses)
• RC7 and experimental zone was presented earlier to the ISOLDE integration meeting, zone needs power, cooling water, pressurized air
• Proposed timeline: start beam at AD as soon as possible, installation of RC7 starting in summer, to be finished in Q4 2025, commissioning of RC6 and RC7 slated for Q1/2 in 2026, test transport or real transport planned for Q2/3 2026. -> co-activities during the earlier ISOLDE LS3 to be coordinated with the ISOLDE LS3 activities 

10:20 → 10:30 WP2: The RC6 beam line

Speakers: Pablo Arrutia (CERN), et. al.

• ZQNAs are ready, but kept on storage until installation in the machine (need one week of preparation)
• Layout DB to be done by BE-OP and BE-CSS 
• Simulation of the dynamic part of the beamline operation to be discussed offline

10:30 → 10:40 WP3: Vacuum

Speaker: Dr Jose Antonio Ferreira Somoza (CERN)

WP3_20250703.pptx

• Procurement well under way, many pieces available already or expected soon
• Vacuum acceptance tests: first QP tested (outgasses a lot since it is the standard design), bender was tested and accepted, zqna's were already tested before being stored 
• Vacuum layout is 100% defined, to solve helium propagation probelem, two extra irises were added to the design, booster turbo pumps added to last two turbo pumps for better compression ratio
• Installation planned for end of 2025, pending on availablity for all beamline equipments; 
• Request for collecting vacuum signals required by users (PLCs, etc)
• Still need to define where to place primary pumps

10:40 → 10:50 WP4: Beam instrumentation

Speakers: Chiara Pasquino (CERN), Federico Roncarolo (CERN), Miguel Martin Nieto (CERN)

• Parts are being machined, components are ordered
• Parts delivery slated for september
• Assembly, calibration, ~ 1.5 months -> tentative delivery date in November ' 25; collector plates probably Q1 2026
• Calibration setup to be reused from HIE-ISOLDE DBs 
• Racks already installed on mezzannine, TDC is installed, FESA class still needs to be adapted
• MagneToF high-gain and low-gain modes needed new developements, ongoing, will be integrated in already available PAM infrastructure
• FESA class requirements discussed with users, is feasible with provided hardware

10:50 → 11:00 WP5: Handling and transport

Speaker: Roberto Rinaldesi (CERN)

- no updates from transport as further information on weight distribution of the final PUMA layout is needed to design ISOLDE load spreader (at least 3 months lead time)

11:00 → 11:10 WP6: BEAM optics and elements

Speakers: Lukas Nies (CERN), Magdalena Kowalska (CERN)

• all of the mounts are installed
• optics are in the process of being vacuum tested and installed
• high-voltage cage design is progressing
