Power Absorption Calculation for Electron Cyclotron Resonance Heating in H-1 Heliac

Nagasaki, Kazunobu; Shats, Michael; Smith, Heather; Punzmann, Horst

Description

Power absorption is calculated for electron cyclotron resonance heating (ECRH) in the H-1 heliac device by using a ray tracing numerical code. The three-dimensional magnetic field structure and the bean shape of flux surfaces are considered. The calculation results show that the second harmonic extraordinary mode heating is effective even at low density if the launching direction is properly adjusted. The localized power absorption profile can be shifted from on-axis to off-axis by controlling...[Show more]
