title = "ECRH of overdense plasmas in TJ-K",
abstract = "In the torsatron TJ-K, low-temperature plasmas are created by means of microwaves at 2.45 GHz and 8.25 GHz. The plasmas are characterized as overdense which means that densities higher than the cut-off density are achieved. Studies in a wide parameter space show that the power deposition occurs predominantly at the upper-hybrid resonance. This can be seen in the electron-energy distribution function and the measured wave electric field. Full wave simulations support these measurements. An array antenna is presented which allows to scan the angle of incidence by variation of the microwave frequency.",
