Abstract
Partial sawtooth crashes in ohmic plasmas on TFTR are analysed using t he high resolution electron cyclotron emission (ECE) image reconstruct ion technique. During the partial sawtooth crash, (m, n) = (2, 2) or ( 3, 3) modes are dominant. The (1, 1) mode occurs after the partial cra sh. The partial sawtooth crash can be explained by the flattening of t he (2, 2) or (3, 3) islands due to the localized reconnection.
