This paper presents a new 320 GHz solid-state source interferometer installed in the Heliotron J helical device for exploring the physics of high-density plasmas. The interferometry system allows for high time resolution measurements in the microsecond range and successfully measured electron density in high-density plasma experiments. The new system can be used for routine diagnostics.
A new 320 GHz solid-state source interferometer is installed in the Heliotron J helical device to explore the physics of high-density plasmas (ne > 2-3 x 10(19) m(-3), typically) realized with advanced fueling techniques. This interferometry system is of the Michelson type and is based on the heterodyne principle, with two independent solid-state sources that can deliver an output power of up to 50 mW. A high time resolution measurement of mu s can be derived by tuning the frequency of one source in the frequency range of 312-324 GHz on the new system, which can realize the fluctuation measurement. We successfully measured the line-averaged electron density in high-density plasma experiments. The measured density agreed well with a microwave interferometer measurement using a different viewing chord, demonstrating that the new system can be used for routine diagnostics of electron density in Heliotron J.
