The National Fusion Collaboratory focuses onenabling fusion scientists to explore Grid capabilitiesin support of experimental science. Fusion experimentsare structured as a series of plasma pulses initiatedroughly every 20 minutes. In the between-pulseintervals scientists perform data analysis and discussresults to reach decisions affecting changes to the nextplasma pulse. This interaction can be made moreefficient by performing more analysis and engagingmore expertise from a geographically distributed teamof scientists and resources. In this paper, we describea virtual control room experiment that unitescollaborative, visualization, and Grid technologies toprovide such environment and shows how theircombined effect can advance experimental science. Wealso report on FusionGrid services whose use duringthe fusion experimental cycle became possible for thefirst time thanks to this technology. We also describethe Access Grid, experimental data presentation tools,and agreement-based resource management andworkflow systems enabling time-bounded end-to-endapplication execution. The first virtual control roomexperiment represented a mock-up of a remoteinteraction with the DIII-D control room and waspresented at SC03 and later reviewed at aninternational ITER Grid Workshop.
