ISIS Operating Schedule - future years
From April 2026 to March 2027, 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 March to early September 2027. This would mean no proposal round in October 2026, and a round in April 2027 to allocate time from September 2027 to March 2028.
