Abstract :
A millimeter wave plasma diagnostic instrument is being developed for the KSTAR tokamak to image electron density fluctuations via microwave imaging reflectometry (MIR), and electron temperature profiles and fluctuations via electron cyclotron emission imaging (ECEI). The 2-D active and passive MMW imaging systems will be capable of simultaneously imaging fluctuations over an extended portion of the KSTAR plasma. System details, including preliminary optical and electronics designs, FSS notch filter, and antenna prototypes, are presented along with a discussion of a number of implementation options which include plasma coverage, spatial resolution, channel numbers, IF and RF bandwidths.
