Recent studies on TFTR of high density disruptions have made significant advances in closing the gap between theoretical models of disruptions and the experimental data. For the first time, an (m,n) = (1,1) ``cold bubble`` precursor to the high density disruptions has been experimentally observed. The precursor resembles the ``vacuum bubble`` model of disruptions first proposed by Kadomtsev and Pogutse.
