Laser Performance Monitoring at Centre for Advanced Laser Applications (CALA) — •Michael Bachhammer, Sonja Gerlach, Leonard Doyle, Felix Balling, Florian Schweiger, and Jörg Schreiber — Faculty of Physics, Ludwig-Maximilians-Universität München, Garching, Germany

One major interest of our research in the field of laser-driven ion acceleration is establishing a stable source of energetic ions. However, shot-to-shot fluctuations as well as long-term drifts of the PW-class Advanced Titanium Sapphire Laser ATLAS can cause instabilities and a significant degradation of the ion-beam performance. This prompted us to investigate and monitor the stability of our 1-Hz laser system. To this end, a 'Performance Report' has been implemented, which is automatically generated daily and summarizes the performance of the laser system throughout the day. This allows the detection of correlated fluctuations. The report is enabled by a Tango-Controls [1] based control system and comprises not only important laser parameters such as laser energy, spectrum and beam profile but also environmental factors like temperatures at different positions in the laser chain. In a next step we will implement diagnostics that enable more direct correlation of laser parameters with ion bunch parameters with the ultimate goal of enabling active control. This work was supported by the BMBF within project 01IS17048 and the Centre for Advanced Laser Applications.
