A critical assessment of the feasibility of IFE chambers has been initiated. This work seeks to define design windows and explore in detail the tradeoffs for various chamber concepts. The work is performed in an integrated and self-consistent manner by including all key elements of IFE chambers, including target physics, target fabrication, injection and tracking, final optics interface and protection, chamber engineering, safety and environment. Chamber concepts are being considered in a sequential fashion; initial studies reported here have concentrated on dry wall options. The goals and approach of the program are described and preliminary results reported.
