Auxiliary ECR heating system for the gas dynamic trap [PDF]
Physics of Plasmas, 2012 Physics aspects of a new system for electron cyclotron resonance heating (ECRH) at the magnetic mirror device Gas Dynamic Trap (GDT, Budker Institute, Novosibirsk) are discussed. This system based on two 400 kW/54.5 GHz gyrotrons is aimed at increasing the electron temperature up to the range 250–350 eV for improved energy confinement of hot ions.

Dynamics of plasma confinement during ECR heating in the L-2M stellarator
Journal of Physics: Conference Series, 2018 Dynamics of plasma confinement was considered in the experiments on ECR plasma heating in the L-2M stellarator. It was ascertained that four stages can be distinguished in the process of plasma heating and further cooling. In each stage, plasma confinement has its own distinctive features.

Selective ECR heating of trapped/passing electrons in the W7-X stellarator [PDF]
AIP Conference Proceedings, 2014 Using specific features of the magnetic equilibrium in the W7-X stellarator, ECRH scenarios with X2 and X3 modes are discussed. The aim is to explore the possibility of selective heating of the different classes of electrons, passing and trapped, by different RF beams with different frequencies, which can be launched from ports located in different ...

ECR Heating in a Helicon Device [PDF]
AIP Conference Proceedings, 2006 This paper presents a microwave electron cyclotron resonance heating system for the linear magnetized VINETA helicon device. Thereby, a relatively cold helicon wave generated plasma is heated by resonant electron cyclotron waves. The magnetic field configuration is adjusted such that resonant energy transfer occurs locally to heat the plasma electrons.
