Abstract : In this dissertation the authors present an in depth multidimensional computer simulation study of the ion-acoustic instability (the relative electron-ion drift velocity is less than the electron thermal velocity) in the presence of collinear constant electric and magnetic fields, and investigate the anomalous d.c. resistivity due to its turbulence as a function of both these external fields. The constant electric field is in a regime greater than the Dreicer critical limit, but much less than a field which would accelerate an average electron to its thermal velocity in less than an ion plasma time.
