Multichannel millimeter wave interferometer for W7-AS
A newly designed 10-channel microwave interferometer for line integrated electron density measurements at the experiment W7-AS stellarator is described. The probing signals in the frequency range of 160-162 GHz are generated by Gunn oscillators with subsequent frequency doublers. Double conversion heterodyne receivers with 2 MHz bandwidth are used for detection. This article gives a detailed technical description of the system and demonstrates its usefulness by means of an experimental example.
