The proposed installation of an experimental beam line to exploit the photon flux from the FEL Undulator on the Brookhaven VUV ring is described. It is shown that under the normal operating conditions of the VUV ring the Undulator should produce an intense flux of photons in a highly collimated beam in the energy range from 5 to 200 eV. It is intended to construct a beam line based on a McPherson 225 monochromator which will allow an experimental program in the range 5 to 30 eV. The optical layout of the beamline is discussed with particular emphasis on the requirements of coupling a highly collimated source to such a monochromator. The experimental program is designed to utilize either the high photon flux with medium resolution or a more modest flux with the potential high resolution to be obtained from the monochromator. Planned experiments include High k-space resolution Angle-resolved photoemission, high resolution gas phase studies and spin resolved photoemission from solid surfaces.
