A num­ber of pro­to­type mag­net­ic struc­tures for a su­per­con­duct­ing un­du­la­tor have been suc­cess­ful­ly built and test­ed. The field qual­i­ty of a test de­vice was mea­sured in a ver­ti­cal dewar; the phase er­rors were 7.1 deg. at the max­i­mum de­sign cur­rent with no phase shim­ming. The Ad­vanced Pho­ton Source (APS) spec­i­fi­ca­tion for over­all tra­jec­to­ry was met using the end com­pen­sa­tion coils. Sev­er­al Hall probes have been cal­i­brat­ed at cryo­genic tem­per­a­tures. The de­sign for a cryo­stat to hold the un­du­la­tor for in­stal­la­tion in the APS stor­age ring is near­ing com­ple­tion, and a cryo­genic mea­sure­ment fa­cil­i­ty to mea­sure the mag­net­ic field of the com­plet­ed un­du­la­tor is under de­vel­op­ment.
