-The S800 ((D. Bazin, J.A. Caggiano, B.M. Sherrill, J. Yurkon, and A. Zeller, Nuclear Instruments and Methods in Physics Research B 204, 629 (2003) )) is a superconducting spectrograph used for reaction studies with high-energy radioactive beams produced at the [[http://www.nscl.msu.edu|NSCL Coupled-Cyclotron Facility (CCF)]] and the [[http://www.nscl.msu.edu/exp/devices#a1900|A1900 Separator]] ((D.J. Morrissey, B.M. Sherrill, M. Steiner, A. Stolz, and I. Wiedenhoever, Nuclear Instruments and Methods in Physics Research B 204, 90 (2003) )). It was designed for high-precision measurements of scattering angles (ΔΘ=2 msr) and momentum (p/Δp=2×10<sup>4</sup>), and large momentum and solid-angle acceptances (ΔΩ=20 msr, Δp/p=6%). The S800 layout shown in the next figure depicts the two parts of the S800: the analysis line and the spectrograph.

-The spectrograph consist of two [[Magnets#Spectrograph Quadrupole Doublet|quadrupoles]], a [[Magnets#Spectrograph Sextupole|sextupole]] and two big [[Magnets#Spectrograph Dipoles|dipoles]] assembled in a QQ-S-DD configuration (segment 8) that spans vertically from the target station to the focal plane, with a total length of 18 m. The sequence of pictures below show the quadrupole doublet at the "entrance" of the spectrograph (left); the side view of the spectrograph as seen from the south bottom level of the S3 vault; and the second dipole as seen from the top level.
