ABSTRACT:
There is disclosed a magnetic alignment device and method for its fabrication in which the aligned magnetic moments of a gas enclosed within a container have an increased relaxation time, hence an increase signal to noise output.
One embodiment is a nuclear magnetic resonance gyroscope including a container for gas having a layer of rubidium hydride on its inner surface. Enclosed within the container is rubidium vapor and xenon-131 gas.
The layer of rubidium hydride is manufactured by reacting hydrogen gas and rubidium at a temperature between approximately 70.degree. and about 250.degree. C. In one specific method, a layer of rubidium hydride is formed by heating rubidium and hydrogen gas at about 85.degree. for about 7 days.
