Preliminary simulation analysis of the temperature fluctuation effect on Taiji-1 Laser interferometer

نویسندگان

چکیده

Space-borne gravitational wave detection imposes a demanding requirement on the sensitivity of laser interferometer. Among all disturbances that affect measurement accuracy interferometer, temperature fluctuations contribute significantly. In this paper, structure model and interference path design Taiji-1 interferometer have been used to conduct preliminary simulation analysis fluctuation noise through finite element method. The temperature, displacement optical difference obtained theoretically analyzed. results are consistent with theoretical analysis, which shows thermal–structural–optical scheme adopted in paper is reasonable. With actual control we estimate system, below order mK, node within [Formula: see text][Formula: text]pm, arm length amplitude also text]pm.
