An introduction describes the critical importance of the relativistic electron rings to the EBT concept and the significance of electron-cyclotron heating to the formation and steady state of the rings. The relation and distinctive features of the present work to previous calculations of ring power balance are delineated. The plasma model used as the basis of the calculations is set up. Special emphasis is given to the development and description of a relativistically correct quasilinear expression. Equations for collisional, synchrotron radiation, and bremsstrahlung losses which are necessary for determining steady state annulus temperatures are written down. The energy loss and quasilinear heating equations are adapted to EBT geometry. A detailed accounting is given of spatial locations where quasilinear heating occurs for various electron cyclotron harmonics. The final section makes concluding remarks about the JAYCOR EBT ring model. A brief synopsis is given of the significant points deduced from the model, particularly as they relate to recent EBT experiments. Based on the results, suggestions for future refinements in the JAYCOR ring model are made which can permit improvement in the theoretical description of the EBT ring.
