Abstract: With the rapid progress of frontier research such as quantum control technology, nuclear-magnetic-resonance gyroscope(NMRG), which features significant advantages of high precision, small size, low power consumption and so on, has become one of the main development directions of high precision micro-miniature gyroscope in the future. Transverse relaxation time of Xe nucleon contained in the vapor cell is an important parameter to measure the performance of the vapor cell, which directly affects the random gyro angle migration. Accurate and rapid measurement of transverse relaxation time is conducive to the development of vapor cell with better performance. Based on the deduced principle of transverse relaxation time measurement of nucleon and LabVIEW software platform, an automatic measurement system for the transverse relaxation time of vapor cell nucleon was designed, which realized the functions of temperature control, xenon resonance frequency finding, magnetic field control and data processing and storage. The experimental results show that the automatic test system which has high measurement efficiency and test precision, stable and reliable work ability, and good man-machine interaction provides an effective measurement to test the vapor cell performance of NMRG.
