Summary
The world's second hard X-ray free-electron laser after LCLS: first lasing on 7 June 2011 (RIKEN history). It is compact thanks to its 5.7 GHz C-band linear accelerator (RIKEN). Construction started in April 2006 and general user operation in March 2012; it has three beamlines (SPring-8 on the same site has 57) (MEXT, 29 September 2026).
Now as of 9 Nov 2026
In user operation. The main event on the site is the SPring-8 upgrade (see SPring-8): according to MEXT, SPring-8 will stop for about a year from the second half of Japanese fiscal year 2027, and general use of SPring-8-II will begin during fiscal year 2029. The government's "Integrated Innovation Strategy 2026" asks for enough operating time at SPring-8/SACLA and J-PARC during that period so that research can continue (MEXT, 29 September 2026).
