Embarrassed, and I'll admit being both ignorant and pompous. Metal is used 
in the ampoules. Won't go into any other details than that. Sorry Corby.

I'm changing the thread to cesium tube details!


Maybe so, however I went out to the junk pile and pulled all the ovens (a
wide range of vintage from early 5060A to later 5061A/B and various FTS).

There were 35 of them and they all have the electrode on the top (or side
for the FTS) for burning open the burst diaphragm.

The only HP vintage I have not opened up is the 5071A/5061A/B mini small
diameter tube.

I will open one up within a week and take some PIX as well as PIX of
opening up the oven.

My gut instinct is that they would not have changed a tried an true
method so late in the game.

John Akermann has graciously offered to provide a space for me on his
website to post the pictures.

I'll take some PIX of other areas of the tube also while I'm in there.

Best Regards,

Corby Dawson
