The biggest obstacle is the emittance growth caused by CSR through a dogleg composed of a bend and a bend-back of 3 degrees, which seriously restricts on the operational peak current less than 2.5 kA. In order to solve this problem, we built a dual DBA-based dogleg using a 0.3 MW highly stable pulse power-supply in winter 2016. The full-performance pulse-by-pulse multi-FEL operation was successfully achieved in February 2017. This will be introduced in the user operation as a standard mode after Summer 2017 via the test use scheduled before the summer shutdown. On the other hand, the SXFEL user operation at BL1 has been started since 2016 and now two XFELs (BL2, BL3) and one SXFEL (BL1) beamlines are available simultaneously for user experiments at SACLA. This presentation shows the present status of SACLA focusing on the above topics. PB - JACoW CP - Geneva, Switzerland ER -
