Paper Abstract

In this paper, a design of a novel thermo-structure for measuring thermal drift of optics in a next generation interferometer is presented. The novel thermo-structure is used to change the temperature of interferometer under test (IUT) by radiation since the measurement is operated in vacuum to exclude the affect from air. Besides, the thermo-structure is made of multilayers, 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 the system is evaluated by finite element analysis and simulation results show that it can achieve a uniform temperature field which temperature difference is less than 0.02°C and reduce perturbation of environmental radiation from 2°C down to 0.03°C.
