Measured results and discussion on vacuum seal-off property of a cooling system for high-temperature superconducting antennas are reported. The cooling system was designed and fabricated and its cryogenic packaging was investigated. Vacuum seal-off tests were performed and high vacuum for thermal isolation could be kept for 25 days. On the cold stage of the system, some kinds of gas, including H2O and CO2, were adsorbed on a cold stage.
