摘要

In this paper, a design of a novel thermo-structure for measuring thermal drift of optics in a next generation interferometeris presented. The novel thermo-structure is used to change the temperature of interferometer under test (IUT) by radiationsince the measurement is operated in vacuum to exclude the affect from air. Besides, the thermo-structure is made ofmultilayers, intergrated with thermo electric coolers as the source of heat, which can provide a uniform temperature field.In addition, the thermo-structure can also protect the IUT from disturbance of environmental radiation. Performance of thesystem is evaluated by finite element analysis and simulation results show that it can achieve a uniform temperature fieldwhich temperature difference is less than 0.02 ℃ and reduce perturbation of environmental radiation from 2 ℃ down to0.03 ℃.
