AB  - The Laser Megajoule (LMJ) is a 176-beam laser facility, located at the CEA CESTA Laboratory near Bordeaux (France). It is designed to deliver about 1.5 MJ of energy to targets, for high energy density physics experiments, including fusion experiments. Six 8-beams bundles are currently operational. The Front-End is the LMJ subsystem built to deliver the laser pulse which will be amplified into the bundles. It consists of 4 laser seeders, producing the laser pulses with the expected specificities and 88 Pre-Amplifier Modules (PAM). In this paper, we introduce the architecture of the Front-End’s control system which coordinate the operations of the laser seeders and the PAMs’s control systems. We will discuss the ability of the laser seeders and their control systems to inject the 88 PAMs almost independently. Then we will deal with the functions that enable the expected laser performances in terms of energy, spatial and temporal shapes. Finally, the technics used to validate and optimize the operation of the software involved in the Front-End’s equipment performance will be detailed.
