Progress in JT-60 experiments

The Japan Atomic Energy Research Institute completed in April 1985 the construction of the large tokamak JT-60, which constitutes a focus of the Second Phase of the Japanese fusion development program under the Atomic Energy Commission started in 1975. Initial experiments of JT-60 were carried out in hydrogen plasma after the completion of the device. Full installation and testing of the heating devices was completed in July 1986 and subsequently the heating experiment was initiated. The target parameters were achieved in deuterium-equivalent values in September 1987 by high power heating of high density hydrogen plasmas at high plasma current. JT-60 has entered the phase of advanced experiments in 1988. (author)
