Abstract

An estimate was made of the operational and measurement range for the “Reflectometry for the Electron Density Profile Measurements” diagnostics that is being developed for the T-15MD device. The latest changes related to the design of the diagnostics are discussed, parameters of the diagnostics components are presented, and the expected signal-to-noise ratio is given. Also, an assessment of the maximum tolerable level of density fluctuations for diagnostics is presented and compared with measurement results obtained on the other devices. This study is of interest for professionals who develop microwave diagnostics for fusion machines.
