This article describes the diagnostic complex for investigation of plasma electromagnetic emission during beam-plasma interaction. Multichannel polychromator is used for measurements of spectral power density in frequency band of 100 ÷ 500 GHz. Two-channel polarimeter is used for obtaining information about emission polarization. The new cryogenic detector will be used for measurements of electromagnetic radiation over 600 GHz. Calorimetric detectors can also be used to increase the number of possible spatial registration points. Because experiments data interpretation depend on local plasma parameters such as plasma density or temperature diagnostic, complex include system of registration of density based on CO2-interferometry and Nd-laser scattering. The information about plasma temperature is obtained from diamagnetic loops.
