Abstract

LHCb is the dedicated heavy flavour experiment at the Large Hadron Collider at CERN. The partially assembled silicon vertex locator (VELO) of the LHCb experiment has been tested in a beam test. The data from this beam test have been used to determine the performance of the VELO alignment algorithm. The relative alignment of the two silicon sensors in a module and the relative alignment of the modules has been extracted. This alignment is shown to be accurate at a level of approximately 2 μ m and 0.1 mrad for translations and rotations, respectively, in the plane of the sensors. A single hit precision at normal track incidence of about 10 μ m is obtained for the sensors. The alignment of the system is shown to be stable at better than the 10 μ m level under air to vacuum pressure changes and mechanical movements of the assembled system. © 2008 Elsevier B.V.
