The Transition
March 2008
4 Dees installed in CMS
Need to Shepherd our resources
as the group’s Brownian motion diminishes
What do we do?
My personal opinion, particularly for the first (EE) LHC run :
PPD – duty to show EE working as expected
duty to show VPTs are stable
(does not necessarily imply continuous calibration
responsibility)

2.5 years of LHC running
Hardware
PPD – responsibility for all things ‘VPT’
keep it all running during LHC on periods
interventions/repairs/upgrades during short/long shutdowns
- Special care/analysis at each substantial luminosity increase
VPT leakage currents, stability, noise…….
- Analysis of data – to check EE performance

Is that all ?????
Rumours that
the Great Bear in the East is
Stirring !!
We may be confronted with all this much sooner than expected !
