ISIS Operating Schedule - future years
From April – December 2026, we expect to run four cycles which will be allocated in proposal rounds 26-1 (deadline October 2025) and 26-2 (deadline April 2026).
We are currently anticipating having an extended shutdown for accelerator and beamline work from January – August 2027. This would mean no proposal round in October 2026, and a round in April 2027 to allocate time from September 2027 – March 2028.
