| Abstract | The Laser MegaJoule (LMJ), a 176-beam laser facility developed by CEA, is located at the CEA CESTA site near Bordeaux. The LMJ facility is part of the French Simulation Program, which combines improvement of theoretical models and data used in various fields of physics, high performance numerical simulations and experimental validation. It is designed to deliver about 1.4 MJ of energy on targets, for high energy density physics experiments, including fusion experiments. With 120 operational beams at the end of 2023, operational capabilities are gradually increasing until the full completion of the LMJ facility by 2025. To verify the synchronization of the precise delay generators, used on each bundle, a new timing diagnostic has been designed to observe the 1w and 3w fiducial signals. Meanwhile, due to electronic obsolescence, a new modified prototype precise of a delay generator, with ’new and old channels’, has been tested and compared. In this paper, a review of the LMJ synchronization report is given with a description of the first timing diagnostic as well as an overview of the LMJ delay generator obsolescence update. It also presents some leads for a future timing system. | |
