Abstract: DESY is planning to upgrade its current storage ring PETRA III into the ultra-lowemittance photon source PETRA IV. The current H6BA cell design for the PETRA IV latticewill allow for insertion devices of up to 4 m length in the standard straight sections. In order toallow some beamlines to not only benefit from the performance improvements by the machinebut also from the undulators, we started looking into using advanced undulator schemes aswell. We decided to start the design of cryogenically cooled permanent magnet undulators(CPMUs) based on (Nd,Pr)FeB magnets for PETRA IV, since this technique has already beenproven successfully by various other facilities. We will present the planned design for themagnet keepers, the pole tuning mechanism as well as a testbed for keepers under cryogenicconditions. We will also show a preliminary design for the in-situ Hall-probe bench currentlydeveloped for the upcoming PETRA IV CPMUs.
