Description
Radio frequency waves in the range of the lower hybrid resonance are coupled to a plasma of enhanced electron temperature (ca. 106 K) and reduced collision frequency (ca. 7 x 105 s-1). The experiment demonstrates the persistance of resonance behavior even under this conditions. Radial eigenmodes are dominant, but exhibit - as compared to linear theoretical models - additional damping with an effective collision frequency in the order of 3 x 107 s-1. For the conditions considered this effect is attributable to Landau damping. (orig.)
Abstract (German)
Im Bereich der unteren Hybridresonanz werden Radiowellen in ein Plasma erhoehter Elektronentemperatur (ca. 106 K) und reduzierter Stossfrequenz (ungefaehr 7 x 105 s-1) eingekoppelt. Im Experiment zeigt sich selbst unter diesen Bedingungen Resonanzverhalten. Radiale Eigenmoden sind dominant, zeigen jedoch in Vergleich zu linearen theoretischen Modellen zusaetzliche Daempfung mit einer effektiven Stossfrequenz von ungefaehr 3 x 107 s-1. Unter den betrachteten Bedingungen laesst sich dieser Effekt auf Landau-Daempfung zurueckfuehren. (orig.)Additional details
