Abstract

In the Rijnhuizen Tokamak project filamentation of the electron temperature has been observed in additionally heated discharges applying electron cyclotron heating. Fila ments are sharp peaks on the electron temperature with an amplitude of up to 1 keV in a 2 keV ambient plasma and a width of 5—10 mm. They are observed with a high resolu tion double pulse Thomson scattering diagnostic. Filaments are statistically significant structures. Experiments show that it is likely that filaments are periodic structures with a m/n=1 or higher order periodicity.
