In development of the scientifically stipulated technology for production of porous getters the necessity to apply the high-sensitive methods for determination of the activation temperature, compatible with the technology of exhaust tube pumping, appears. In this work a complex methods for determining the temperature of activating porous getters using an experimental scheme, simulating the conditions of activating porous getters using the conventional technology of exhaust tube pumping, has been proposed. The model of the gas load formation on the interior pumping equipment has been considered in conditions of physical and chemical processes simulation in the volume of heated housing of magnetron with pumping. It has been shown that according to the theory of chemical reactions the flows of thermal desorption are generated from both, the serial reaction theory or parallel-serial reactions theory. The sorption properties of the non-evaporable getters have been defined by the graph as the temperature-time dependence mass yield of complex chemical reactions of the interaction between the gas workload with surface and interior volume of the getter sample. The change in the mass of the getter sample has been measured on the vacuum thermo-gravimetric installation microbalance uninterruptedly with frequency of one measurement at a second during the whole period of measurement. The threshold sensitivity of microbalance was 10 g, the maximum weight was 5 g. Using the parallel-serial reaction theory, the minimal temperature of thermal activation of the non-evaporable getter from Ti-V(30 at. %) alloy, which is the main parameter of the technology using the interior pumping equipment, has been experimentally defined for the first time. The minimal activation temperature was 393 °C for the non-isothermal period of standard heat treatment process with the heating rate of 10 ºC/min and the given vacuum parameters. For estimation of free surface roughness changing of the getter sample subjected to internal saturation in the hydrogen atmosphere the scanning electron microscopy has been used. The cracks and micro-sized monocrystals have been discovered, probably, as titanium hydride TiH. The cracking positively manifests itself on the sorption activity of the getter positively due to appearance of new atomically clean surfaces. However, the cracks formation can contribute to appearance of the getter sample fracture, because the gas workload by hydrogen is the factor, which limits the durability of the work of the getter.
