We conducted methodological studies to evaluate the possibility of conducting experiments on gas releasefrom pre-saturated samples on a plasma-beam installation. One of the tasks of obtaining reliable data onthe parameters of the interaction of hydrogen isotope ions with materials of the NNR is to conductmethodically correct post-test experiments on the study of gas release from the investigated samplessubjected to ion irradiation. The paper presents three stages of research. In the first stage, experiments werecon-ducted on saturation and gas release with the sample from tungsten. At the second stage, experimentswere performed with a tungsten sample on saturation with its deuterium and degassing under stepwiseheating conditions. At the third stage, experiments were conducted on gas release with vanadium samples,with maximum sensitivity for dissolved gas in the sample. The results of calculations of the temperaturefield on the sample are presented. It is shown that, on the whole, it reflects the experimentally observedeffect on a significant sample temperature gradient.
