Abstract: A method for storage of a material comprising:Providing an electrical glow discharge device comprising a container for enclosing a gas atmosphere, said container including a wall forming a storage glow discharge electrode, and a sacrificial glow discharge electrode located within said container;Introducing into said container a gas atmosphere containing the material to be stored;Maintaining the pressure within said container at a value suitable for electrical glow discharge;Electrically energizing the storage and sacrificial glow discharge elctrodes to effect glow discharge between the electrodes to ionize said material in said atmosphere;Controlling the electrical supply such that ions of said material bombard and are implanted into said wall forming said storage electrode and such that ions of said material also bombard said sacrificial electrode, the iom bombardment of said sacrificial electrode being sufficient to cause sputtering thereof such that the sputtered material is deposited on said wall forming
