HYSPEC is a truly unique direct geometry inelastic scattering instrument that has been approved for placement at the Spallation Neutron Souce.  It combines time-of-flight spectroscopy with focusing Bragg optics to enhance the flux on small single crystal samples.  It will be located on a beam line looking at a coupled H₂ moderator and will use a 20-25 meter supermirror guide to transport the neutron beam.  A counter- rotating chopper pair will monochromate the beam and determine the neutron burst width.  A short distance from the chopper pair a vertical focusing crystal is placed in a drum shield that will compress the beam of size 15(h) x 4 (w) cm² so as to maximize the flux on the sampleof a small size of 2(h) x 4(w) cm2. Collimators and beam definers  placed before and after the sample will allow standard sample environment equipment to be used, covering a wide range of temperatures and magnetic fields.  A moveable detector bank about 4.5 m from the sample will cover a horizontal range of 60° and a vertical range of ±7.5°. An important feature envisioned in the HYSPEC design is a polarized beam operation which is achieved by using a Heusler crystal for a monochromator and supermirror benders for polarization analysis of the scattered beam.  HYSPEC is a moderate resolution instrument optimized for an incident energy range 5<EI<60 meV, where it outperforms, in terms of flux on sample, the other inelastic instruments by at least a factor of 2 and up to a factor of 10.
