3rd Joint HiLumi LHC – LARP Annual Meeting 11-5 November, Daresbury Laboratory LHQ Status and Plans Giorgio Ambrosio Fermilab With contributions from the whole LARP magnet team The HiLumi LHC Design Study is included in the High Luminosity LHC project and is partly funded by the European Commission within the Framework Programme 7 Capacities Specific Programme, Grant Agreement 284404 Work supported by the US LHC Accelerator Research Program (LARP) through US Department of Energy contracts DE-AC02-07CH11359, DE-AC02-98CH10886, DE-AC02-05CH11231, and DE-AC02-76SF00515
Long HQ Plans • Following the 2012 DOE review the Long HQ work has been redirected toward RISK MITIGATION for MQXF and significantly reduced • Long coils with cored cable, braided insulation, stainless steel end parts, … • Plan: 2 practice coils, 1 or 2 coils for single test (mirror structure) G. Ambrosio
Long HQ Status • Electrical strength tests on practice coil #1: • Heater-coil up to 5 kV (75 um polyimide) • Impulse test up to 3 kV • Practice coil #2: opportunity for improving winding of marginally stable cables at FNAL • Coil #3 fabrication in progress • Winding w tool & binder • To be tested in spring 2014 G.
