HYDROGEN ABSORBING ALLOYS APPLICATION IN HYDROGEN MASER

Hydrogen absorbing alloys have been widely used today to store the hydrogen,they also can be applied to the Hydrogen Maser.The paper describes the hydrogen storage principle of the La-Ni al- loys and its application in the Hydrogen Maser of Shanghai Astronomical Observatory.To improve the reliability or reduce the possibility of leak,the structure of the hydrogen supplier has been im- proved.Since this hydrogen storage technology is initially applied in Shanghai Astronomical Observ- atory hydrogen Maser,further experiment is now being carried out.By contrast with other hydrogen supplier,the alloys hydrogen storage methods have the obvious advantage that the volume of alloys hydrogen storage container can be reduced and the pressure in the container can be decreased.
