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

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

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
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 manner
to bring us to having the upgrade completed by 2016”

(in my view) LHCb upgrade should plan independently




Can we plan the VELO upgrade for a 6-8 month “hot swap”, preceded by
prior installations during shutdown periods, especially 2012


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
E.g. optical fibers.. But funding…
Please give me input before Feb 7
