The theory of diffusion processes within glass microspheres indicates that a temperature-controlled storage and release of helium in hollow glass microspheres is possible. This work aims to show how this property is applicable for a gas storage system or a gas generator on satellites. Test facilities for filling and outgassing should be tested to find out how much helium is stored for different pressures. Furthermore, a storage tank for use in satellites is constructed. The entire system should be examined in some test series. To achieve a rapid release of helium, a high heating power due to the poor thermal conductivity of the glass microspheres is required. Satellites have a limited power capacity, so it is important to minimize the heating power. To this end, the glass microspheres are coated. A copper coating is deposited by magnetron sputtering. Measurements of the thermal conductivity should show if the thermal conductivity of glass microspheres increases, by this treatment.
