A cryopumping system suitable for testing xenon ion thrusters was designed and tested. The aimed temperature of a CP (cryopanel) was below 50 K, since the vapor pressure of xenon use low enough at the temperature. The system-alone-tests showed the attained temperature of the CP was below 50 K and the CP could evacuate xenon with a pumping speed of over 600.000 l/s. But while an ion thruster was operating, the speed fell to 40.000 l/s and a continuous operational time was restricted to about 90 minutes.
