Resonant Pitch-Angle Scattering Of Runaway-Electrons by Externally-launched Helicon Waves in the DIII-D Tokamak
Hari Choudhury, Jeffrey Lestz, Carlos Paz-Soldan +12
Resonant wave-particle interactions between externally launched helicon waves (also known as whistler waves) and runaway electrons (REs) have been demonstrated on the DIII-D tokama…

Runaway electron interactions with whistler waves in tokamak plasmas: energy-dependent transport scaling
Yashika Ghai, D. Del-Castillo-Negrete, D. A. Spong +1
Resonant interactions between high energy runaway electrons (REs) and whistler waves are a promising mechanism for RE mitigation in tokamak plasmas. While prior studies have largel…
