The Laser MegaJoule (LMJ), a 176-beam laser French facility, located at the CEA* CESTA close to Bordeaux is part of the French Simulation Program, for improvement of theoretical models, high performance numerical simulations and experimental validations. It is designed to deliver about 1.4 MJ of energy on targets, for plasma and fusion experiments. With 15 bundles operational at the end of 2023, the operational capabilities are increasing gradually until the full completion of the LMJ facility by 2025. With the increasing of the Power Conditioning Modules (PCM), it has been observed more and more instabilities in the synchronization and the repeatability of the PCM’s triggering. For experiments based on 10 or more bundles, it has resulted in the issue of coupling the LMJ bundles with the PETAL laser and in the safety shutdown of the PCM due to the timeout of capacitors under high voltage. In this paper, a description of the LMJ PCM is first given. Then, the considered problem is presented with a detailed analysis and the software solution is finally presented with experimental results showing the gain in the reliability and effectiveness of the PCM during the LMJ-PETAL shots.
