Lay summary
LHCb is an experiment designed for precise measurements of CP violation and rare B decays at the LHC collider at CERN. Its main physics aims are to elucidate the flavour structure in the quark sector, and hopefully observe signals from New Physics.LHCb is expected to be ready to record LHC's first collisions in 2009, and deploy its full physics program as soon as the LHC reaches a luminosity of 2 10^32 cm-2 s-1.The particle physics group of EPFL's Laboratory for High Energy Physics has been working on LHCb since the beginning of the project in 1995 and plays important roles in the leadership of the experiment.The main hardware responsibilities of the group are the development, construction and maintenance of the- common readout boards TELL1 and electronics for LHCb's silicon vertex detector;- silicon Inner Tracker detector, in collaboration with other institutes (in particular University of Zurich) involved in LHCb's Silicon Tracker project.The objectives for the 2-year funding period 2008-2010 are:- Commissioning of the hardware devices under our responsibility (TELL1 boards and firmware, VELO power supplies and readout chain, and all aspects of the Inner Tracker), without and with LHC beams, such as to render them fully operational as soon as possible.- Calibration, performance monitoring and software alignment of the Inner Tracker.- Participation in the first data analysis and physics measurements.- In addition, considering possible future involvement in the LHCb upgrade (and also in preparation for the next experiment), start of new R&D activities for an upgraded TELL1 board and in the area of fibre tracking.We ask SNSF to support the above-mentioned LHCb activities at LPHE through salaries as well as consumables and travel expenses. We also request funds from SNSF for equipment money to start the ?bre tracking R&D and the work on a new version of TELL1. Funding for capital investment in the LHCb detector and for maintenance and operations is asked for in separate requests.

Abstract

LHCb is an experiment designed for precise measurements of CPviolation and rare B decays at the LHC collider at CERN. Its mainphysics aims are to elucidate the flavour structure in the quark sector, and hopefully observe signals from New Physics.LHCb is expected to be ready to record LHC's first collisions in 2008, and deploy its full physics program as soon as the LHC reaches a luminosity of 2 10^32 cm-2 s-1.The particle physics group in Lausanne, now at EPFL's Laboratory for High-Energy Physics (LPHE), has worked on LHCb since the beginning of the project in 1995 and plays important roles in the leadership of the experiment.The main construction responsibilities of the group are: - Development and construction of the common readout boards TELL1 and of the electronics for LHCb's silicon vertex detector.- Development and construction of the silicon Inner Tracker detector, in collaboration with other institutes (in particular University of Zurich) involved in LHCb's Silicon Tracker project.The objectives for the forthcoming 2-year funding period 2008-2010 are:- Commissioning of the hardware devices under our responsibility (TELL1 boards and firmware, VELO power supplies and readout chain, and all aspects of the Inner Tracker), without and with LHC beams, such as to render them fully operational as soon as possible.- Calibration, performance monitoring and software alignment of the Inner Tracker.- Participation in the first data analysis and physics measurements.- In addition, considering possible future involvement in the LHCb upgrade (and also in preparation for the next experiment), start of new R\&D activities for an upgraded TELL1 board and in the area of fibre tracking.
