Summary: The LHC is the next collider will be put into operation at CERN (Geneva) in 2007. It will generate collisions protón-protón in which they attain a center of mass energy of 14 TeV and will be capable of operating at a brightness nominal until 1034cm 2s-1. The colisionador LHC will be four independent experiments. The detector in which the work of this thesis is the CMS (Compact Muon Solenoid), which is designed with general purpose. Among the new particles predicted by the standard model it is the bosón of Higgs, which is particularly relevant for all new physics leading partner. The CMS detector comprises a multitude of subdetectores grouped in the interior and exterior of the superconducting solenoid magnet. Different subdetectores which constitute it have a role in detecting specific either to know the energy (calorimeters) to detect the trajectories of charged particles of which can know the time for being immersed in the magnetic field of solenoid (tracker and cameras of muones). To get a good resolution at the time of muones (which are symbols for the channels decay most relevant to the disintegration of bosón of Higgs) requires a high field magnético.El solenoid CMS reach 4 T. But to achieve maintain the high resolution over the entire trajectory of muones (facing radially around the experiment CMS), it is essential that path is to be rebuilt with high accuracy from the detector central traces (tracker), located in the area more internal CMS until the camera system muones, located at the outer part of CMS. This, in short, requires a good understanding of the relative position between the two subsystems (alignment between the two), which is what it is dedicated system alignment LINK. This thesis is part of the analysis and etudio of system components alignment LINK (temperature sensor, optical proximity, tilt and position 2D) and their response in various conditions of operation of CMS.
