  1. VELO upgrade news 03 February 2010

  2. VELO Upgrade Survey • Final answers received in the last few days • Coordinators have been invited for all the work packages – 2 have so far agreed! • Establish contact with all interested parties and summarise progress to date in upgrade meetings • Coordinate and plan activities • Prepare for TDR • Maintain web pages linked from http://lbtwiki.cern.ch/bin/view/VELO/VELOUpgradeRnD

  3. Reactions to Survey • Missing items – good suggestions received (even with volunteers!) and the work packages will be updated • e.g. consideration of mixed technologies for baseline design • Specifications for strip chip • Not enough emphasis given to the implementation of the chip readout scheme • Sensor work package too big – to be split into planar, diamond and 3d • Big enthusiasm in the institutes for constructing “module 0’s” whether this be timepix assemblies, chips on diamond, “first staves” etc. etc. This links to all work packages

  5. News from Chamonix • Long run scheduled until late 2011 • Followed by long stop (50-70 weeks) • LHCb integrated luminosity per year: 0.5 fb-1 in 2010, 1 fb-1 in 2011, 2 fb-1 in 2013… • Thereafter the running cycles will be 18-24 month runs interspersed with 6-8 month shutdowns (e.g. for Linac) • Injector complex upgrade plans changing rapidly • Same for LHC (e.g. no Inner Triplet upgrades, probably) • Inner Detector GPD upgrades (with the technology which is most overlapping with what we are planning) are postponed to 2020+ (after 600-700 fb-1) • This puts flavour physics firmly on the map in the coming years • And the LHCb upgrade as THE major upgrade project on the physics horizon, bridging the gap to the GPD upgrades

  6. News from Chamonix • More news will be given at an upgrade leaders’ meeting February 10th • “We would then like each of you to give a 5 min presentation on how you see your upgrade plans progressing, in such a mannerto bring us to having the upgrade completed by 2016” • (in my view) LHCb upgrade should plan independently • As soon as we upgrade we will benefit from a factor 2-3 in hadron trigger efficiency • After the upgrade our performance will scale with luminosity • No reason to delay it once we have collected ~6-10 fb-1 which we are well on course to do by 2016 • Can we plan the VELO upgrade for a 6-8 month “hot swap”, preceded by prior installations during shutdown periods, especially 2012 • E.g. optical fibers.. But funding… • Please give me input before Feb 7
