Development and testing of a gallium fixed-point space infrared radiation reference blackbody source for space infrared radiometric calibration. The blackbody cavity aperture has a diameter of 60 mm, a depth of 230 mm, and a cone angle of 32°, and is filled with 7N high-purity gallium. All tests were carried out at the Remote Sensing Calibration Laboratory of the National Institute of Metrology, China, including: (1) On December 11, 2020, the emissivity of the gallium fixed-point space infrared radiation reference blackbody source was tested using the controlled ambient background radiation method; (2) From November 2020 to December 2022, a total of 7 phase transition reproducibility tests were conducted on the first-generation gallium fixed-point space infrared radiation reference blackbody source in a vacuum simulation chamber, with data recorded by a Fluke 1595; (3) From March 2021 to March 2023, a total of 7 phase transition reproducibility tests were conducted on the second-generation gallium fixed-point space infrared radiation reference blackbody source in a vacuum simulation chamber, with data recorded by a Fluke 1595.
