Abstract

A temporally and spatially resolved optical pyrometer system has been fielded on Gekko XII experiments. The system is based on the self-emission measurements with a gated optical imager (GOI) and a streaked optical pyrometer (SOP). Both detectors measure the intensity of the self-emission from laser-produced plasmas at the wavelength of 450 nm with a bandpass filter with a width of ∼10 nm in FWHM. The measurements were calibrated with different methods, and both results agreed with each other within 30 as previously reported [T. Morita, Astrophys. Space Sci. 336, 283 (2011)]10.1007/s10509-010- 0525-5. As a tool for measuring the properties of low-density plasmas, the system is applicable for the measurements of the electron temperature and density in collisionless shock experiments [Y. Kuramitsu, Phys. Rev. Lett. 106, 175002 (2011)]10.1103/PhysRevLett.106.175002.
