A Spectrally and Temporally Resolved Optical Pyrometer for Measurements of Optical Self-Emission and Reflectometry on OMEGA EP

ORAL

Abstract

Many experiments are conducted on the OMEGA EP laser to investigate materials at high pressure. For these experiments, measurements of the material conditions are critical. It is particularly important to characterize the temperature. Temperature measurements are regularly made using an absolutely calibrated streaked optical pyrometer (SOP) under the assumption that the material has a uniform emissivity in the spectral band measured. A new SOP with spectral resolution (SOP-spec) is being implemented for measurements of spectrally resolved self-emission and reflectometry in the 400- to 900-nm-wavelength range. Self-emission and reflectometry measurements have been made with a prototype system. A dedicated diagnostic is in the process of being implemented and will be available for use on experiments in 2023. In this talk, diagnostic capabilities and planned first experiments will be discussed.
