EXPERIMENTAL OBSERVATIONS OF DISRUPTIONS IN JET
Themain aim of JET is the study of plasmas in which alpha particle heating is a significant part of the input power and this depends on reaching a value of the produce n-iT-itau-E>5.10**21 m**-3s**-1.keV. With ohmic heating alone all 3 parameters are about a factor of 3 too small. The maximum value of n reached up until now is 3.75 10**19 m**-3 and limited by the high density disruption. It has been shown elsewhere that additional heating brings this limit up with a factor 1.5 to 2 which is not enough. Moreover it is undesirable to induce a disruption at every pulse when heating is switched off. Study of high density disruptions is therefore a key issue for JET.
