Abstract:
We discuss the design and expected performance of the OK-5
FEL, which will replace in 2002 the OK-4 FEL operating now
at the Duke storage ring. The OK-5 FEL is the first
distributed optical klystron with variable polarization. The
design of wigglers and matching sections is flexible for
providing optimal conditions for variety of operation modes.
In this paper we present calculations of the main OK-5 FEL
parameters such as its tuning range, gain and lasing power.
Based on our calculations we present the predictions for the
OK-5 gamma-ray source. We conclude with description of the
current status of the OK-5 FEL and plans for its
installation.
