SIRIUS is a Synchrotron Light Source Facility based on a 3 GeV electron storage ring with 518 m circumfer-ence and 250 pm.rad emittance. The facility was built and is operated by the Brazilian Synchrotron Light Laboratory (LNLS), located in the CNPEM campus, in Campinas, Brazil. The accelerator commissioning and operation has been split into 2 phases: Phase0, corresponding to the initial accelerator commissioning with 6 beamlines, has been completed, and the project is now in preparation for Phase1, with full accelerator design performance and 14 beamlines in operation. We report on the status of SIRI-US last year operation and ongoing activities towards achieving completion of Phase1.

Sirius is a Synchrotron Light Source based on a 3 GeV electron storage ring with 518 meters circumference and 250 pm.rad emittance. The facility is built and operated by the Brazilian Synchrotron Light Laboratory (LNLS), located in the CNPEM campus, in Campinas. A beam stability task force was recently created to identify and mitigate the orbit disturbances at various time scales. This work presents studies regarding ground motion (land subsidence caused by groundwater extraction), improvements in the temperature control of the storage ring (SR) tunnel air conditioning (AC) system, vibration measurements in accelerator components and the efforts concerning the reduction of the power supplies’ ripple. The fast orbit feedback implementation and other future perspectives will also be discussed.
