The NSLS Prototype Small-Gap Undulator (PSGU) will serve as a tool to study lifetime degradation and the onset of beam instabilities as the beam duct aperture is decreased. The device will consist of variable-gap vacuum vessel had a permanent magnet undulator, with independent magnet-gap control. The vacuum vessel design attempts to minimize both residual gas pressures and beam impedances. The undulator will be 320 mm long and utilizes a pure-permanent-magnet structure with 6 blocks per 16 mm period. For a nominal operating aperture of 4 mm, PSGU will produce a peak brightness in the fundamental and third harmonic of 7 {times} 10{sup 16} and 1 {times} 10{sup 16} photons{sm bullet}sec{sup {minus}1}{sm bullet}mrad{sup {minus}2}mm{sup {minus}2}{sm bullet}(0.1% BW){sup {minus}1} at photon energies of 2.5 keV and 7.5 keV, respectively. 5 refs., 3 figs., 2 tabs.
