Tracking in the context of the European project AIDA
Description
This work was conducted in the context of a vertex detector (VXD) composed of CMOS sensors for ILD and in the context of the beam telescope of the european project AIDA. The provides the results of beam tests for the new telescope components: the SALAT super-planes and the PLUME double sided ladders. The thesis addresses the added value in terms of alignment, of double sided layers of CMOS sensors for the VXD of ILD. A new standalone alignment method of each of the three double sided layers of VXD with the mini-vectors built on each overlapping zone between the consecutive ladders is analysed. Such alignment was validated with high momentum particles. However, only the beam background particles, with lower momentum, can provide the minimum statistic for this kind of alignment. Thus, the beam background noise was studied and the occupancy rate of the VXD sensors was studied. This led to a reassessment of the readout speed for the sensors of each layer of the VXD. (author)
Abstract (French)
Ce travail se place dans le contexte du detecteur de vertex (VXD) compose de capteurs CMOS pour l'ILC, et dans celui du telescope en faisceau du projet europeen AIDA. La these inclut les tests en faisceau des elements du telescope AIDA: les super-plans SALAT et les echelles double faces PLUME. Elle questionne la valeur ajoutee en terme d'alignement, des couches double faces de capteurs CMOS pour le VXD de l'ILD. Une nouvelle methode d'alignement autonome de chacune des 3 double couches du VXD grace aux minivecteurs construits sur chaque zone de recouvrement inter-echelle est proposee et a ete testee avec des particules de haute impulsion. Cependant, seules les particules du bruit de fond faisceau, de plus basses impulsions, permettent l'obtention d'une statistique suffisante pour cet alignement. Ce bruit de fond a alors ete etudie et une estimation des taux d'occupation des capteurs du VXD a conduit a une re-estimation des vitesses de lecture des capteurs de chaque couche du VXD. (auteur)
