A standard radio frequency coaxial connector is modified so that a plastic insulating sleeve can be mounted in the wall of a vacuum chamber. This eliminates ground loops and interference from cable connections.
Radio frequency noise generation from ion engine exhausts, noting electron cyclotron radiation from penning discharge engine
Cross modulation of cesium vapor at radio, microwave and optical frequencies by means of optical pumping
Isolation of closely spaced transmitting and receiving frequencies of an antenna without insertion loss by filtering the receiver input is accomplished by an inner conductor with two winding helices and an outer conductor of aluminum. A tuning slug is at either end of the inner conductor form.
