Read e-book online Electron Cyclotron Emission and Electron Cyclotron Resonance PDF

By Ronald Prater

This complaints quantity, the 16th in a biannual sequence, provides a image of the kingdom of present learn around the globe on Electron Cyclotron Emission (ECE) and Electron Cyclotron Resonance Heating (ECRH) and comparable applied sciences. The papers tackle the physics, either thought and test, of ECE and ECRH. The applied sciences of excessive strength millimeter-wave assets -- gyrotrons -- and transmission strains and launchers are integrated. the point of interest is on physics and know-how proper to the learn and improvement of nuclear fusion.

The extension so far consists of 2-frequency units, which use single diamond-disk vacuum-windows to transmit power at the natural resonances of these disks (105 & 140 GHz). For the last unit of this extension two additional intermediate non-resonant frequencies are foreseen, requiring new window concepts. For the torus a polarisation-independent double-disk window has been developed.

Solutions like this seem reasonable for stellarators, since there is little free energy in the magnetic configuration and stellarator power plants are being designed to lie on the stable part of the fusion power curve to perturbations in temperature.
