The propagation and absorption of ion Bernstein waves (IBW) in a helical system was investigated. IBW was excited using a folded waveguide antenna to improve energy confinement. It was found that the electron Landau damping was so strong that the IBW was absorbed before it reached the cyclotron resonance layer where ion heating was expected to occur. It was noted that the two cases of circular tokamak and straight helical configuration possessed their own symmetry.
