CERN Luminosity Task Force Established to re-evaluate commissioning, operation, consolidation & upgrade plans in

CERN Luminosity Task Force Established to re-evaluate commissioning, operation, consolidation & upgrade plans in light of the results of the Chamonix workshop: • General considerations: (a) need to minimize the number of interventions and maximize the luminosity gain from each one (due to installation & ramp up time, radiation issues etc. ); (b) global optimization is required involving new Quads, cryogenics, powering, correctors, collimators etc. • Schedule considerations: (a) radiation lifetime limit of present IR will be reached around 2020; (b) spares policy should be decoupled from upgrade plans; • Recommendations: (a) Delay the inner triplet replacement to a single HL-LHC upgrade around 2020; (b) technology decision Nb. Ti vs. Nb 3 Sn is required in 2014. CM 14, 4/26/2010 Magnet Systems Status and Plans Gian. Luca Sabbi

Length considerations for the IR upgrade • HQ short sample gradient is 200 T/m

Length considerations for the IR upgrade • HQ short sample gradient is 200 T/m @ 4. 5 K & 220 T/m @ 1. 9 K • Assume operation at 170 T/m and same basic layout as baseline LHC magnet length is ~7. 4 m (Q 1 & Q 3), 6. 4 m (Q 2 a & Q 2 b) • Half length elements: ~4. 1 m (Q 1/Q 3), ~3. 5 m (Q 2 a/b) w/10% factor Technical comparison: - Full length elements are clearly preferred for optimal IR performance - Full length elements should be less costly for production Ø However, they require new infrastructure - Full length elements need to be demonstrated experimentally Ø This can impact the schedule and decision process - Half-length elements could be considered as a fall-back solution Ø Loss of efficiency is 5 -15% depending on implementation CM 14, 4/26/2010 Magnet Systems Status and Plans Gian.

Medium term Nb 3 Sn development (2012 -14) Goal: demonstrate full-length magnet performance to minimize the technical and schedule risk to the project • The existing (FNAL) infrastructure allows fabrication of coils up to 6 m length. • As a first step, we could aim at testing of individual 6 m long coils in a suitable support structure by 2014 • The 6 m long coils could be based on LR, LQ or HQ design Ø The 120 mm (HQ) design is strongly preferred since it could directly lead to assembly of a 6 m long IR Quad prototype Ø However, is more expensive to fabricate and test then the other two alternatives • Results of 2 m model Quadrupoles and 6 m coil scale-up will provide required information for detailed IR design and project planning/initiation CM 14, 4/26/2010 Magnet Systems Status and Plans Gian.
