Abstract
In view of the characteristics of the test platform of vacuum capability evaluation for laser thruster, which have such difficulties as high vacuum degree, adjustable- cubage quadrate container, the seal design for horizontal and vertically moving port, etc. The test system is composed of adjustable-cubage quadrate container, vacuum system, mass spectrum device, mobile port, and control system. The device was achieved high degree of vacuum by dry pumps and molecular pumps. Residual gases were analyzed by mass spectrum device. Quadrate vacuum container obtained adjustable-cubage and seal capability by mobile port. The degree of vacuum 5.0×10-4Pa is achieved. In addition, Leakage of 1.0×10-8Pam3/s is obtained, and such residual elements as carbon, hydrogen, nitrogen, oxygen, were analyzed, vacuum and optics experiments were carried out, and the security and reliability were guaranteed.
