Description

SIRIUS is a 4th generation synchrotron light source built and operated by the Brazilian Synchrotron Light Laboratory (LNLS) currently operating in top-up mode at 100 mA beam current, driven by a temporary RF system comprised of one PETRA 7-cell cavity and two 65 kW solid state amplifiers (SSAs). In the upcoming update, two SRF cavities will be installed along with two more SSAs, which will allow the operation with 200 mA and, by the end of 2026, a third harmonic cavity will be installed and it will be possible to reach the nominal beam current of 350 mA. For the final RF system, four new 65 kW SSAs, which are being developed in house, will be installed. These amplifiers consists of 900 W amplifier modules combined through a cavity combiner and this presentation will showcase the project's current status, along with the results obtained from the characterization of the SSAs modules, the 10-way quarter-wavelength and 8-way Wilkinson power dividers, and the cavity combiner.
