Experimental investigations on drift waves in linear magnetized plasmas
Two main aspects concerning drift wave dynamics in linear, magnetized plasma devices are addressed in the work: In part I of the thesis, drift waves are studied in a helicon plasma. The plasma parameter regime is characterized by comparably high collision frequencies and comparably high plasma-p exceeding the electron-ion mass ratio. Single Langmui...

The nonlinear dynamics of the modulational instability of drift waves and the associated zonal flows
The linear and nonlinear dynamics of zonal flows and their interactions with drift wave turbulence is considered in the simple but illuminating generalized Charney-Hasegawa-Mima model due to Smolyakov et. al. (A.I. Smolyakov, P.H. Diamond and V.I. Shevchenko, Phys. Plasmas, 7, 1349 (2000)). Two positive definite, exact, integral invariants associat...
