AB - This work presents the first experimental characterization of cavity modes trapped within a plasma column in an axis-symmetric magnetic trap. Trapped wave has been characterized by means of a movable antenna as a function of the B_{min}/B_{ECR} ratio and plasma parameters. The study demonstrates that E.M waves can be enclosed two R-cutoff layers, close to the B minimum position. Results suggest that the trapped waves consist of waves propagating across the magnetic field and storing large part of the E.M. power. If R-cut-off is removed by increasing the density, trapped waves are not detected longer. A typical Electron Energy Distribution Function composed by two different electron populations is measured in the layer where trapped waves are revealed, suggesting that additional heating is occurring.
