A Device for Precise Isothermal Sample Annealing in an Accelerator Chamber

Abstract

A device has been developed for isothermal sample annealing in the chamber of an accelerator facility. The application of the nuclear reaction analysis is allowed during the sample annealing. Flowing liquid nitrogen and a resistive heater are used for the sample cooling and heating. Using the device, sample annealing is carried out in the temperature range of 110–500 K and the temperature is maintained with an accuracy of 1 K. The obtained characteristics meet the requirements of precision experiments on deuterium diffusion in solids, including at cryogenic temperatures.
