  We consider the design of a haloscope experiment (ORGAN) to probe for axions
at 26.6 GHz. The motivation for this search is to perform the first direct test
of a result which claims a possible axion signal at this frequency. There are
many technical issues and optimisations that must be considered in the design
of a high mass axion haloscope. We discuss the current status of the ORGAN
experiment, as well as its future. We also discuss low mass axion haloscopes
employing lumped 3D LC resonators.
