Superheterodyne radiometer to measure electron temperature profile in Aditya tokamak

Among the coherent, and incoherent radiations emanating out of the tokamak plasmas, the latter gives vital information about the electron temperature. Electron cyclotron emission (ECE) is a powerful diagnostic tool for the measurement of electron temperature in tokamak plasma. In this paper, we present the design of the microwave superheterodyne radiometer to make spectrally resolved measurements of the ECE in the 60–90 GHz frequency range.
