To accommodate the schedules for various speakers, some Ideas were presented in Sessions other than the Task Force which actually has jurisdiction over the proposal. The last column in the tables below indicates the actual Task Force which will evaluate and prioritize the proposal: LH = lower hybrid, RF = ICRF physics, AT = Advanced Tokamak, BP = Burning Plasma, TR = Transport, OPS = Operations and Diagnostic Development, Edge = Edge and Divertor.
