Alignment of the LHCb Vertex Locator
LHCb will commence data taking as the first dedicated heavy flavour experiment at a hadron collider in 2008. A very high hit precision from its vertex detector (VELO) is essential to meet the tight requirements of vertex reconstruction in B-physics. The single hit precision of the VELO is better than 10 μm. However, the VELO is operated only 8 mm from the beam and must be retracted and reinsert...
متن کاملStatus and prospects of the LHCb Vertex Locator
The Vertex Locator of the LHCb experiment is a dedicated subdetector for the reconstruction of primary and secondary vertices in b-hadron decays. The vertex detector features two halves with 21 modules each, mounted on retractable bases. Each module consists of two half-disk silicon micro-strip sensors measuring hits in R and Φ coordinates. The strip pitch ranges from 40 to about 100 μm. A vacu...

The LHCb experiment (Large Hadron Collider beauty) is one of the four experiments under construction at the LHC (Large Hadron Collider) at CERN near Geneva. It is planned to start in 2007 and its goal is the study of b-quark physics. The LHC is a circular accelerator in which collide protons-protons at a center-of-mass energy of √ s = 14 TeV. This generates a large number of high energy bb̄ pair...
متن کاملVELO software alignment , Part III : the alignment of the relative sensor positions
The LHCb Vertex Locator contains 42 silicon sensor modules. Each module has two silicon sensors. A method for determining the relative alignment of the silicon sensors within each module from data is presented. The software implementation details are discussed. Monte-Carlo simulation studies are described that demonstrate an alignment precision of 1.3 μm is obtained in the sensor plane. LHCb Pu...
متن کاملThe LHCb upgrade detector
The LHCb experiment has been designed to perform precision measurements of CP asymmetries and to investigate potential effects of physics beyond the Standard Model. Results obtained from data collected in 2010 and 2011 show that the detector is robust and functioning well. While LHCb will be able to measure a host of interesting channels in heavy flavour decays in the coming years, a limit of a...
