The CIK is a microwave source which relies on the negative mass instability for electron bunching, as opposed to the linear-drift ballistic bunching of conventional klystrons. We are testing a proof-of-principle (POP) CIK to verify the predictions of our analyses, which indicate that the CIK is feasible in the 2-10 GHz region at MW to G W power levels. Such a device can be quite compact, and 3-D numerical sirnulations show strong particle bunching for efficient operation. The POP device is

For maximum flexibility and to allow testing over a wide range of parameters, the POP device is modular, incorporating a multisection, helical beam tube to allow variation of the interaction length. Results of the analyses and status of the experiment will be presented.
