Description: We describe a variable-emittance filter designed for the Electron Laser Facility (ELF). The filter attenuates the 4.5-MeV, 6-kA Experimental Test Accelerator (ETA) beam, permitting electrons only which fall within a given region of phase space (r, dr/dz) to pass. Initial experimental results are presented.
