Power converter specs/type for SHiP Muon Shield

Wednesday 26 Feb 2025, 14:00 → 16:00 Europe/Zurich

17/1-007 (CERN)

"pro memoria", a few immediate actions mentioned during the meeting which would help for the next step:

SY/EPC:

• provide a browse-through list of PCs from catalogue to be considered  by SHiP (eliminating those that are clearly not suitable or that can no longer be procured)
• share dedicated document on current stability of PCs  => here, added 13.3.2025: EDMS Nr. 2048827.
• quench protection / discharging: provide contact in TE-MPE ? (for future discussions)
• available DC lines: provide contact in EN/EL ? (to get precises characteristics)

 

SHiP:

• narrow down excitation properties of muon shield magnets to progress on defining the PC specs.

14:00 → 14:20 Overview of SHiP magnets (as of today)

• muon shield options (full warm versus mixed superconducting + warm), including special magnets: magnetized hadron stopper, warm magnets with integrated neutrino/LDM detectors
• functionalities, overveiw of requirements, mode of operation

Speaker: Massimiliano Ferro-Luzzi (CERN)

14:25 → 14:45 Power converters support at CERN

• what is included in support (procurement, installation, commissioning, maintenance, repair, decommissioning) under which conditions,
• what PCs are supported at the "horizon 2030" or so (relevant for SHiP), existing and upcoming,
• an overview of PCs and their characteristics (picture, power ratings, stability, ramp speed limits, control interface, dimensions, weight, etc.), and also cost (even if approximate),
• what type of protection is included / not included,
• where is detailed documentation on those PCs,
• imitations about location of installation ? (near magnets ? far from magnets ?), SEE resilience ?
• what could be re-used from existing hardware

Speakers: Ivan Josifovic (CERN), Yves Gaillard (CERN)
