Waveguide HOM dampers are widely used in high current RF cavities, as waveguides are natural high pass RF filters and can easily handle high RF power. In this presentation, the author will review a few typical waveguide HOM load designs, especially the recently developed high power HOM loads for bERLinpro and BESSY-VSR. We will report the RF-thermal-mechanical design, fabrication technology, absorber material choice, as well as the testing results of these HOM loads.
