Abstract

The phenomenon of density pump-out or the degradation of particle confinement is observed for plasmas with electron cyclotron heating (ECH) in the compact helical system. It is confirmed that the enhancement of the particle flux with ECH is triggered by the production of electrons accelerated perpendicularly to the magnetic field with ECH.
