At what energy level will x rays be created? I want to demonstrate this to my class, but I'm concerned about my tesla coil / CRT combination.

I don't get how this works in this demonstration. This shows only cathode end bein connected to anything. Nothin else is connected. Why electrons decide to flight out towards the anode? Or are they flying out in all directions, but are visible only where they hit phosphorous?
