Description
The Centre for Advanced Laser Applications (CALA) operates the petawatt laser system ATLAS-3000, primarily for applications in particle acceleration. These experiments rely on stable and reproducible laser beam properties to ensure control over the resulting particle beams. At the same time, the system is used by a large number of experimentalists, posing a challenge for maintaining consistent operating conditions.
To address this, an automated laser alignment system based on Tango Controls has been developed. Feedback loops between diagnostic cameras and motorized mirrors are used to align the beam to its nominal position. For improved usability, a dedicated user interface has been implemented. Over the past year, the system has progressed from initial proof-of-principle experiments to routine daily operation by multiple users. In addition to improving reproducibility, it reduces the daily time required to bring the laser into operation by approximately 30 minutes.
