Abstract
A vacuum device has an envelope and a getter assembly mounted within the envelope. The getter assembly includes a reservoir for containing getter material and a deflector having a surface located opposite the getter material and is oriented to deflect the getter material in a predetermined direction within the vacuum device. The deflector surface has raised and/or depressed portions, such as ribs or undulations, in the direction of diffusion of the getter material. These portions reduce the accumulation of getter material on the deflector during getterfiring, resulting in a much reduced likelihood that getter material particles may break loose from the deflector. By preventing loose particles within the vacuum device, the possibility of a short-circuit in the vacuum device is reduced.
