It has been 26 years since SPring-8 was inaugurated in 1997. The conceptual design report (CDR) for SPring-8-II was published in 2014, but the budget remained untouched. Only the beamline reorganization was executed before the accelerator refurbishment was decided. The beamlines have been reorganized into three categories: measurement, experiment, and R&D. A two-dimensional X-ray detector named CITIUS was jointly developed with SONY.

COVID-19 has brought about many changes, but the biggest one is digitalization. The use of robots, remote control, data center establishment, etc., has progressed, and cooperation with supercomputers has also accelerated. Spectroscopic studies have been performed to develop ECMO's thrombus-inhibiting blood tubes. The structural analysis of the COVID-19 virus has been used to develop growth-inhibiting drugs.

Social demand for SPring-8 continues to increase, contributing to the deepening and expansion of SPring-8's application fields. For example, contribution to national resilience, contribution to national semiconductor strategy, contribution to brain science, etc. Industrial use continues to grow. A recent feature is an increase in the rate of paid use. This indicates that confidence in the industry is increasing.

Strong support for R&D contributing to carbon neutrality is highly demanding in the current global environment. On the other hand, since accelerator facilities consume massive electric power to operate, it is also crucial to materialize energy-saving facilities. Based on MBA, SPring-8-II aims to realize a light source that is more than 100 times brighter than the present SPring-8 with less than half the power consumption. The details of the R&D for that will be introduced.

Launching the SPring-8-II project allowed us to consider the next steps for SACLA. We investigate whether there is a way to raise the repetition frequency of the warm cavities to about 1 kHz while using the same or less power than the current SACLA operation.
