A summary of research performed under subject contract is given. The work is in the main concerned with the theory, both linear and non-linear, for the gain of a free electron laser FEL in a strong axial magnetic field. Both wiggler and wiggler-free configuration are considered. An experimental study is described of the transition from helical to non-helical orbits in a wiggler with a guide field. THe exact magnetic field of a filimentary bifilar current-carrying helix is given. The degradation in gain of a FEL without axial guide field due to velocity spread is given. Twelve published papers are appended. Author.
