The X-ray Free-Electron Laser facility, SACLA, has delivered X-ray laser beams to users from March 2012 [1]. Typical user experiments utilize two-dimensional-imaging sensors, which generate 10 MBytes per accelerator beam shot. At 60 Hz beam repetition, the experimental data at the rate of 600 MBytes/second are accumulated using a dedicate data-acquisition (DAQ) system [2]. To analyze such a large amount of data, we developed data-analysis system for SACLA experiments. The system consists of on-line and off-line sections. The on-line section performs on-the-fly filtering using data handling servers, which examine data qualities and records the results onto the database with event-by-event basis. By referring the database, we can select good events before performing off-line analysis. The off-line section performs precise analysis by utilizing high-performance computing system, such as physical image reconstruction and rough three-dimensional structure analysis of the data samples. For the large-scaled image reconstructions, we also plan to use external supercomputer. In this paper, we present overview and future plan of the SACLA analysis system.
