The High Luminosity LHC Frédérick Bordry ECFA High Luminosity LHC Experiments Workshop – 1 st October 2013
Outline - LS1 status (few slides) and 2012 last performance - Run 2 (from LS1 to LS2), LS2 and Run 3 - HL-LHC project - Conclusion The High Luminosity LHC 2 Frédérick Bordry 2 ECFA High Luminosity LHC Experiments Workshop – 1 st October 2013
Long Shutdown 1 LS1 starts as the shutdown to repair the magnet interconnects to allow nominal current in the dipole and lattice quadrupole circuits of the LHC. It has now become a major shutdown which, in addition, includes other repairs, maintenance, consolidation, upgrades and cabling across the whole accelerator complex and the associated experimental facilities. All this in the shadow of the repair of the magnet interconnects. The High Luminosity LHC 3 Frédérick Bordry ECFA High Luminosity LHC Experiments Workshop – 1 st October 2013

Some Limitations: Electron cloud • Reason for running with 50 ns • Scrubbing to suppress electron cloud build up by reducing the secondary electron yield (SEY) • Remains still worrisome in the arcs for 25 ns bunch spacing The High Luminosity LHC 8 Frédérick Bordry ECFA High Luminosity LHC Experiments Workshop – 1 st October 2013
Some Limitations: cont’d UFOs Beam induced heating Radiation to electronics • • Local non-conformities • 20 dumps in 2012 Concerted program of • Timescale 50-200 µs (design, installation) mitigation measures • • Injection protection Conditioning observed (shielding, relocation…) • Worry about 6.5 TeV • devices Premature dump rate • Sync.
