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.

期刊介绍： Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
