Abstract
The OK-4/Duke storage ring free electron laser (FEL) was commissioned in November, 1996 and demonstrated lasing in the near UV and visible ranges (345-413 nm). During one month of operation we performed preliminary measurements of the main parameters of the OK-4 FEL: its gain, lasing power and temporal structure. In addition to lasing, the OK-4/Duke FEL generated a nearly monochromatic (1% FWHM) 12.2 MeV γ-ray beam1. In this paper we describe the status of the main subsystems including the injector system and the ring itself, and discuss future and in-progress upgrades to these systems. We also describe the parameters measured to date of the injector, the storage ring, the generated optical laser beams, and the backscattered γ-ray beam.
