The main aim of National Spherical Torus Experiment(NSTX)is to establish the fusion physics principles of the innovative spherical torus(ST)concept. Physics outcome of the NSTX research program is relevant to near-term applications such as the Volume Neutron Source(VNS)and burning plasmas, and future applications such as the pilot and power plants. The NSTX device began the plasma operations in February 1999 and the plasma current was successfully ramped up to the design value of 1 million amperes(MA)on Dec. 14, 1999. The CHI(Coaxial Helicity Injection)and HHFW(High Harmonic Fast Wave)experiments have also started. Stable CHI discharges of up to 133 kA and 130 msec duration have been produced using 20 kA of injected current. Using eight antennas connected to two transmitters, up to 2 MW of HHFW power was successfully coupled to the plasma. The NBI heating system and associated NBI based diagnostics such as the CHERS(Charge Exchange Recombination Spectroscopy)will be operational in Oct.2000.
