Well I will try anything once if it didn't work that's ok too. I know the tube should be hot for awhile and it helps the vacuum when it cools. I don't even know what the cathode meterial is coated with to be heated off later after its done because it cannot come in contact with air so how would this cesium be put on, brushed and would there be a specific time it can be handled in air befor having to be coated. And what exactly is the getter made of, does it stick on the inside of the tube glass and then hit with high megnetic field to burn it on.
