Dear all, usually I would not try to do so. The tubes are sealed and there are getter materials inside the tube that keep the vacuum on an acceptable level during long-time operation. Opening of the tube housing and breaking this vacuum will (more or less certainly) saturate the getter material, and thus the entire setup needs to be evacuated and the getter needs to be re-activated. Even if you succeed in the physical repair of the tube (I guess the filament is broken?) I doubt that you'll succeed in fitting the vacuum. In any case, the situation may vary from source to source ... Good luck in any case, Dirk
please hands off from a 'do it yourself repair' of a sealed x-ray tube.
Dirk already explaind a bit why.
You need dedicated equipment, dedicated procedures for sealing, pumping and baking the tube as well dedicated knowledge to 'repair' a selad tube, if such a tube is repairable at all.
Such task should be done by the manufacturer or a dedicated workshop.
In the case of an open x-ray tube, things are a bit different.
I have tried to get information from internet not much is known about repairing process of damaged X Ray tubes and answers are not indicative of any company involved in this process
