Abstract
Rasniks elements are foreseen to be used in the CMS alignment system. The large displacements and deformations expected for the different su bdetectors demands large linearity response range of the alignment com ponents. By the use of an integrating sphere coupled to the light sour ce, we have optimized the homogenity of the beam, leading to improveme nt, by factor three, in the linearity range of the Rasnik system with respect to conventional configurations, preserving the measurement pos ition resolution. The range obtained coincides with the maximum reacha ble with the geometry of the used components. (C) 1998 Elsevier Scienc e B.V. All rights reserved.
