A Transport Container for Studying Deuterium Diffusion in Alkaline Metals inside an Accelerator Chamber Using the NRAOL Technique

The construction of a hermetic transport container for mounting alkaline metal samples in the vacuum chamber of an accelerator during online measurements of the deuterium diffusion coefficients in metals is described. A glass capsule containing an alkaline metal sample is unsealed in a special box with an inert gas atmosphere and the sample is placed in a cylindrical hollow at the surface of a flat metal plate of the container. After this, the hermetic transport container with the sample is fixed in place on a stationary holder inside the accelerator chamber and is unsealed after a high vacuum is attained in the chamber. Sodium samples are assessed using the nuclear reaction analysis. It is shown that the sodium purity in oxygen, carbon, and other low- Z elements meets the requirements of the accelerator technique.
