Two ongoing accelerator projects at Helmholtz-Zentrum Berlin (HZB), bERLinpro and BESSY-VSR, need to design three different SRF cavities, a 1.3GHz cavity in bERLinpro and 1.5GHz/1.75GHz cavities in BESSY-VSR. These cavities have adopted waveguide HOM dampers in their design, with a few tens of watts HOM power in each load for bERLinpro and a few hundred watts for BESSY-VSR. JLab is collaborating with HZB prototyping these HOM loads. In this paper, we will report on the integrated RF-thermal-mechanical design of the loads, as well as the fabrication and testing results.
