The instabilities known as compressional Alfven eigenmodes (CAE) and ion cyclotron emission (ICE) in tokamaks resemble the electromagnetic ion cyclotron (EMIC) and “equatorial noise” instabilities in the Van Allen radiation belts. In this Frontier Science experiment, the dependence of CAE and ICE on the hydrogen, deuterium and ³He concentration was measured for ten different fast-ion distributions created by changing the neutral beam parameters: hydrogen/deuterium, co-current/counter-current, tangential/perpendicular, and on-axis/off-axis. Below ω_ci, CAE modes are more unstable at 1.25 T than at 2.1 T and the amplitude increases with increasing hydrogen concentration. Above ω_ci, the ICE is stronger at 2.1 T and hydrogen has little effect.
