Paper Abstract

This paper describes the alignment system developed on the Laser Mégajoule facility, allowing to focus the laser beams and to point the plasma diagnostics on the target. After an overview of the main laser components and alignment architecture, we detail some major equipments as the 6 tele-microscopes used to align the target, the continuous phase plate within the final optics assembly, the plasma diagnostic green pointer and the common reference which is the cornerstone of the chamber center alignment. Finally we present some results obtained on the telemicroscope prototype and a photometric prototype of the common reference. The expected performance of the alignment system will also be discussed.
