Three view electronically scanned interferometer for plasma electron density measurements on the H-1 heliac

Oliver, David; Howard, John; Kumar, Santhosh T. A.; Pretty, D. G.; Blackwell, B. D.


We report the development of a three view electronically scanned millimeter-wave interferometer for plasma electron density profile measurement on the H-1 heliac. The system utilizes an electronically tunable backward-wave oscillator whose output is incident on a fixed blazed diffraction grating such that sweeping the source frequency effects a spatial scan of the plasma cross section. Two diagonal views essentially span most of the plasma cross section, while the horizontal arm views the lower...[Show more]
