Web26 feb. 2024 · Helicon waves have been recently proposed as an off-axis current drive actuator due to their expected high current drive efficiency in the mid-radius region in high beta tokamaks. This current drive efficiency has mostly been calculated ignoring the effects of the plasma in the scrape-off-layer (SOL) in the modeling. Web12 feb. 2014 · The ability to non-inductively drive a large fraction of the toroidal plasma current in magnetically confined plasmas is an essential requirement for steady state fusion reactors such as DEMO. Besides neutral beam injection (NBI), electron-cyclotron resonance heating (ECRH) and lower hybrid wave heating (LH), ion-cyclotron resonance heating … Web3 R. Prater, Radio Frequency Power in Plasmas, April 27-29, 2015 • Helicons are fast waves at a high harmonic (>20) of the ion cyclotron frequency but below the LH frequency (also called ‘whistlers’) • The high frequency does two important things: • Improves the damping, so high performance plasma conditions can provide full damping on the first pass long service in victoria
