LHC Upgrade: Machine / Detector Interface

The most relevant parameters for the detectors

BCO interval: 25ns, 15ns, 12.5ns, 10ns (or 75ns)

Forward area/beam pipe : Would like to move the closest machine element towards the IP

Timescales : assume 2014±2 years

Increased radiation levels (and resulting activation) : Need to improve shielding, moderators, access procedures, and safety in general – important constraint for any change considered

Driven by this plot, but also

by lifetime of IR quads 700 fb-1
