Description
SPARC_LAB is a high-brightness e-beam for SASE-FEL (self-amplified spontaneous emission-FEL) experiments. It consists of a brazeless 1.6-cell S-band RF gun, two travelling wave S-band accelerating structures each 3 meters long, and a 1.4-meter C-band structure that acts as an energy booster. As part of the SABINA project, co-funded by the Lazio Regional Government for consolidation of SPARC_LAB, a significant upgrade of the RF control systems was completed last year. The activity involved the development of software for remote control of LLRF systems, C-band modulator, as well as custom hardware made by the RF service for fast feedbacks and RF synchronization. Algorithms were also developed for statistical and diagnostic analysis of RF signals, with real-time amplitude and phase jitter monitoring capabilities. Development of a custom EPICS application aimed at optimizing system resources is currently underway. Finally, to support conditioning operations, dedicated software has been implemented for automatic RF plant management, which dynamically adjusts RF power and manages interlocks under critical conditions.
