 note = {"Stable discharges longer than one minutes have been obtained with all the heating scheme including electron cyclotron heating (ECH).  Plasma is sustained with neutral beam injection (NBI) or with ion cyclotron resonance frequency (ICRF) with 0.5-1MW. Central Plasma temperature is higher than 1.5keV with density of 1-2x10^19m^-3 until the end of pulses. Full installation of the carbon divertor has contributed to this achievement. This gives a ssufficient base for physics and technology studies from the next campaign. The long pulse operation indicates new possibility in diagnostics and in physics studies. Higher accuracy and reliability is obtained with diagnostics parameter scan, longer integration of signals or two-dimensional measurement. Mechanism of a slow oscillation called ""breathing"" has been discussed. Hydrogen recycling analysis has been carried out and preliminary results are obtained. Based on these results, future program is divided into two categories, that is, i) physics and technology experiments utilizing the long-pulse discharges up to 5 minutes, and ii) extension of the pulse -length toward one hour."},
