You know, like inside of CRT tubes.

Interesting about the heating element on the getter, I'd not heard of that being done before. But shouldn't that regenerate the getter, not activate it? I know that vacuum pumping is always accompanied by heating the vessel or pipe, and this drives out moisture and other contaminants that are bound to the surface of the steel. But I believe the heat also regenerates getters (ie: it drives contaminants out of the getter as well). Once the vacuum space and getter is cleaned up by heating, it can be sealed and the getter is then fresh to pull in any additional contaminants that come off during the lifetime of the vacuum space.
