Spatially resolved soft x‐ray measurements on the ZT‐40M reversed‐field pinch using a surface barrier diode array are reported. In plasma discharges with x‐ray sawteeth present, the sawteeth have anm=0,n=0 character. In normal discharges, without large‐amplitude sawteeth, a new ly observed internalm=1 oscillation is described. This quasicontinuousm=1 mode may be a manifestation of a saturated magnetohydrodynamic tearing mode.
