1mφ Space Chamber


	1mφ Space Chamber can simulate high vacuum and cryogenic background of space and it is possible to evaluate the thermal design and verify the environmental durability of the spacecraft. A cryogenic pump using 20K gaseous helium is used to simulate a high vacuum environment in this facility. The chamber has a black shroud where liquid nitrogen circulates along the surface to simulate a cold and dark environment. It is possible to evaluate the baking effect using QCM. Since the facility has a clean booth, it can be used for thermal vacuum testing of flight model such as small satellites that require cleanliness control.
