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 !
