The induction-accelerator free-electron laser (IFEL) presents an important option for generating high-power millimeter waves for electron cyclotron heating and current drive in CIT. Application of the technology to this purpose requires resolution of a number of technical and physics issues. An effort has been undertaken this year to resolve several of the CIT issues. The interim report for this effort analyzed the control of tritium in the quasi-optical transmission line from the IFEL to the tokamak. It was concluded that the use of cryopumping could reduce tritium to the level that it would not pose a breathing hazard in the IFEL vault and that hands-on maintenance would be possible. Preliminary indications were that likely accident scenarios could be handled safely by closing valves between the tokamak and the IFEL. The present report describes the analyses of physics issues associated with the intense microwave fields during heating of CIT. Constraints and opportunities are identified. Details are provided in the appendices about the topics in the following summaries.
