Notes from HI-ECN3 - BDF Magnetised Hadron Stopper (MHS) Discussion with TE-MSC

 

• Clear motivation from (i) target design optimisation and (ii) sc options for muon shield to study a shorter MHS of length 2.5 m with as high a field as reasonable achievable (> 1.8 T)
• Action: Matt to collect info from Claudia/JL/Rui and SHiP and update FS
• A water-cooled copper design with organic insulator looks suited and makes connecting to the existing magnet cooling circuit (K12 being dismantled)
• A dual coil design looks promising for redundancy:
• Details of the location of the redundant coil to be studied as part of 
• Energy efficiency does not look to be so important for the design -> up tot about 5 kW in DC 
• Add the following points to the FS and circulate on EDMS:
• MHS is NOT in vacuum
• Lifting capacity of 30t of crane
• Importance of establishing the assembly / disassembly procedure with final dismantling in mind
• Action: Matt 
• MHS budget: 1250 MCHF as part of WP4
• Coil(s)
• Yoke material (SS/iron?)
• Services (connections/piping)
• Conceptual / mechanical / integration design work linked to WP4
• Timeline:
• TDR to be published early 2026: Action Matt to contact editorial team
• Final design detailed enough to allow integration studies to be completed (WP4)
• Cost & schedule needed for MTP26
• BC for MHS to be provided to TE-MSC via WP4:
• Action: Matt and JL
