Framework TDR for the LHCb Upgrade : Technical Design Report

2012

Abstract

This document is a Framework Technical Design Report for the upgrade of the LHCb experiment. It adds to the information in the Letter of Intent, in particular concerning the foreseen schedule, cost and participating institutes. Updates are given for the physics performance, based on the experience gained with the first full year of data taking, on the detector requirements and the progress of the sub-system R&D. Within the framework presented here, it is expected that the individual subsystem TDRs will follow on completion of the R&D phase in the next year.
