How it will be done please help

[@jacobb7608]

How did you seal the anode through the glass? What type of vacuum pump(s) are you using?

[@ionizingelectron4773]

The seal is made with some general use "super epoxy" bought from the local hardware store. The pump is a two staged rotary-vane pump capable of producing a ultimate vacuum of 2.25 mTorr (0.3Pa).

Why is it glowing blue?

[@urmilachouhan5319]

When charges gone near metal tube the zinc sulphide layer has a reflection
that's why there is reflection of blue light!
