ISIS continues to be the world’s most successful pulsed spallation neutron source. For the period of this report and during scheduled operating cycles, ISIS delivered a total of 612 mA.hrs of user proton beam to the muon and neutron targets.
Following first neutron production on the ISIS Second Target Station on Sunday 3 August 2008, regular proton beam transport to TS-2 started in September. Routine switching from 50 Hz operation of TS-1 to 40/10 Hz joint operation between the two target stations was achieved in November 2008.
The tables below give beam statistics for the individual cycles in the year 2008-2009, together with year-on-year statistics for ISIS performance.
