  For in­ves­ti­gata­tion to build the cryo­genic un­du­la­tor using bake-able Praseodymium-Iron-Boron(PrFeB) mag­net blocks, a short pe­riod(16.8mm) and fixed gap(5mm) hy­brid un­du­la­tor pro­to­type has been fab­ri­cated at BNL. For this un­du­la­tor, 36 PrFeB mag­net blocks(28 type A, 4 type B, 4 type C) are used. The mag­netic field char­ac­ter­is­tics of the un­du­la­tor heav­ily de­pend on the di­rec­tional uni­for­mity of the mag­ne­ti­za­tion of block sets. The strength and di­rec­tion of mag­ne­ti­za­tion of the PrFeB mag­net blocks are mea­sured using a Helmholtz coil sys­tem. The data in­clude the three vec­tor com­po­nents of the total mag­netic di­pole mo­ment of the blocks and also com­pare with ven­dor mea­sure­meant re­sults.
