The LHCb experiment plans to operate at an LHC luminosity of 2x10**32 /s cm2, or typically one collision per bunch crossing. After about five years it will have recorded a data sample of 10 fb-1. At this time LHCb plans an upgrade to operate the detectors at a significantly increased luminosity that will extend greatly its potential for discovery and study of new phenomena. The key to get such an improvement is to read out the full detector at the LHC crossing rate of 40MHz and to run the trigger in the data acquisition computer farm. Studies performed to optimise the design of the LHCb Upgrade are presented. The RICH detector will require new photon detectors as the current HPDs have encapsulated electronics which only supports reading out up to 1MHz data rate. Flat-panel Photo Multiplier Tubes (PMTs) are evaluated as a photon detector candidate and its properties including pulse height and shape and cross-talk are measured. The particle identification performance is studied as a function of luminosities ranging up to ten times the design as foreseen for the LHCb upgrade. Finally, the performance of flavour tagging using kaons, which strongly relies on RICH particle identification will also be presented
