Abstract :
A helicon-type discharge is realized in a curved magnetic field with end point launching of whistler waves by a flat RF antenna. Standing modes are observed by monitoring conditions of zero reflected power. There are indications of Landau damping, with the phase velocity matching the thermal velocity.
