【 摘 要 】

The work has consisted of three projects. The first one is a continuation of the previous work that was done on the generation of zonal flows due to the four wave modulational instability. In this work, we examined the growth of streamers. This work was done with undergraduate student, and was presented at an APS DPP meeting. A summary of the work is given below. Another project was a study of the stability of curvature driven modes with tied field line geometry. The purpose of this study was to see if this instability was relevant to the observed 'blob' phenomenon in the edge. A summary of this work is given starting in Section II. This work was done with undergraduate student. The final project was an extension of electrostatic work that had been done on the parallel velocity shear instability. In this work, we included electromagnetic effects. We performed the linear stability analysis and discovered a new regime of instability. This work was done in collaboration with undergraduate student, who presented the work at an APS DPP meeting. Details of this are shown in Section III.
