The LHCb VELO: status and upgrade developments

Abstract: The LHCb VErtex LOcator (VELO) is a silicon based vertexing sub-detector which has active silicon positioned only 8 mm from the LHC beams and will operate in an extreme (up to 1.3 x 10 14 1 MeV neutron equivalents / cm 2 / year) and non-uniform radiation environment. The complex design of the VELO silicon sensors exploits oxygenated silicon and n + -on-n technology. Research has been carried out into new materials which could significantly extend the lifetime of silicon detectors at the LHC, these would have p… Show more

“…The VELO module was designed according to the requirements of operating in the harsh LHCb environment. Thus, it had to operate in vacuum conditions within the LHC beam pipe and withstand the extreme radiation environment with over 300 kGy (Private communications with David Hutchcroft, University of Liverpool, UK) accumulated dose during the LHC runs [7].…”
