ptical beam line design for the Duke Free Electron Laser Laboratory

In the Fall of 2000 four crotch chambers were successfully installed on the four corners of our one GeV electron storage ring facility at the Duke Free Electron Laser Laboratory (DFELL). Installation of these crotch chambers has enabled us to achieve higher optical beam power that can be used for a variety of experiments such as medical and materials science in our newly constructed Keck building adjacent to our main FEL building. In this article, the design of optical beam lines and the methodology of delivering beams to the experimental stations will be discussed
