[en] Recent upgrades to the NSTX facility have led to improved plasma performance. Using 5MW of neutral beam injection, plasmas with toroidal β_T (= 2μ₀< p>/B_T² where B_T is the vacuum toroidal field at the plasma geometric center) > 30% have been achieved with normalized β_N (=β_TaB_I/I_p) ∼ 6% · m · T/MA. The highest β discharge exceeded the calculated no-wall β limit for several wall times. The stored energy has reached 390kJ at higher toroidal field (0.55T) corresponding to β_T ∼ 20% and β_N = 5.4. Long pulse (∼1s) high β_p (∼1.5) discharges have also been obtained at higher B_φ (0.5T) with up to 6MW NBI power. The highest energy confinement times, up to 120ms, were observed during H-mode operation which is now routine. Confinement times of ∼ 1.5 times ITER98pby2 for several τ_E are observed during both H-Mode and non-H-Mode discharges. Calculations indicate that many NSTX discharges have very good ion confinement, approaching neoclassical levels. High Harmonic Fast Wave current drive has been demonstrated by comparing discharges with waves launched parallel and anti-parallel to the plasma current.
