A short period, in vacuum undulator for the NSLS X-Ray Ring has been developed and has achieved its project design goals during commissioning studies. The device is called IVUN (In-Vacuum UNdulator) and employs magnet arrays (31 periods, with an 11 mm period) developed at SPring-8, while the requisite vacuum chamber and mechanical systems were developed at the NSLS. At a magnet gap of 3.3 mm, IVUN produces 4.6 keV radiation in the fundamental, with useful photon fluxes in both the 2nd and 3rd harmonics. The magnet gap is adjustable between 2 mm and 10 mm. A brief overview of IVUN is presented, together with initial commissioning results: the dependence of electron beam lifetime and bremsstrahlung on magnet gap, and the output radiation spectrum.
