The laser alignment system for the CMS silicon microstrip tracker
… with aprecision of a few hundred micron. The laser alignment system presented here has been designed for this purpose. Its goal is to measure the deformations of the mechanical support structure of the tracker with a precision better than 100 micron. The alignment system uses laser beams with …

Construction and calibration of the laser alignment system for the CMS tracker
… (Geneva, Switzerland). The inner tracking system of the CMS experiment consisting of silicon detectors will have a diameter of 2.4 meter and a length of 5.4 meter representing the largest silicon tracker ever. About 15000 silicon strip modules create an active silicon area of 200 square …

Expected measurement of the Z production rate with the CMS detector and simulation of the Tracker Laser Alignment System
… are foreseen for 2009. The Compact Muon System (CMS) detector will measure the particles created in the hadron collisions and can confirm the Standard Model by establishing the existence of the Higgs boson, but also search for new phenomena. In order to provide a robust and precise track …
