To prevent partial saturation of a getter by contact with absorbable atmospheric gases when the getter is introduced into a vacuum vessel, a method for introducing and activating the getter and a getter unit includes introducing the getter into the vacuum vessel packaged in a protective sleeve, closing off the vacuum vessel, evacuating the vessel, and opening the protective sleeve only after the evacuation has commenced. The protective sleeve can be opened by the sleeve being made to burst under the action of a protective gas atmosphere that is present.

Method for introducing and activating a getter in a vacuum vessel and getter unit

To treat a surface by a device attracted to the surface by vacuum, it is necessary in most cases to guide a working device with a certain contact pressure over the surface. To be able to set the contact pressure of the working device with little effort, the device according to the invention rests at three points on the surface, one support point being formed by the working device. The force of attraction of the device against the surface is, therefore, accurately distributed to the working device and the other two supports so that the pressure force of the working device can be specifically varied and also controlled by varying the vacuum between the device and the surface.
