Abstract

There is disclosed an evaporable getter device particularly suitable for being used in tubes for the projection of images on wide screen; the device (10), being ring-shaped, comprises a container (11) of powders (12) of barium or calcium compounds, formed of a bottom wall (22) connected to an external wall (20) and an internal wall (21), both sloping or curved towards the outside in their upper portion, to obtain a distribution of barium or calcium vapours compatible with the application.
