Investigation results for electromagnetic radiation emission induced by strong Langmuir turbulence driven by a microsecond relativistic electron beam are presented. The radiation is associated with a plasmon-plasmon merging process, which generates photons at a double plasma frequency in the range of few hundreds GHz. An original radiometric system for radiation spectrum and power measurements is described.
