• The m = l island size or m = 1 deformation of magnetic surfaces during sawtoothcrashes is estimated on TFTR by comparing experimental observations of X-rays andECU electron temperature with a simple simulation which calcculates signals of line-in-tegrated X-ray and local electron temperature assuming rigid rotation of the plasma.Sawteeth oscillations with a slow crash (r..... -tseveral ms) can be simulated by aKadomtsev-type reconnection model in which an m = 1 island grows to the size of theq= l surface during the sawtooth crash. In the sawteeth which have a fast crash (507ts - r.,.,. - 500 zs), the m = 1 island size sometimes (not always) becomes - 1 /2 of thesawtooth inversion radius during the crash phase. The final structure, however, ishard to identify, because of the slow plasma rotation frequenccy. The "Hot Core" ap-pears to move away from the plasma center in a Kadon?tsev-type reconnectionwithout causing very large transport or diffusion.
