Abstract :
The National Synchrotron Light Source (NSLS) prototype small-gap undulator (PSGU) will serve as a tool for studying some of the effects which degrade storage ring performance as the beam duct aperture is decreased. It consists of a variable-gap vacuum vessel and a permanent-magnet, small-period undulator with independent magnet gap control. The design concept of the vacuum vessel, and some details related to it, are presented, followed by a description of the permanent-magnet undulator, its design parameters, and anticipated performance.<>
