       My explanation is quite simple, and believable. Like many other issues 
confronted here, the actual analysis requires crunching some real-world 
numbers. But I don't think it is an atomic physics issue.

       You are assuming a constant E-field in the tube, which is not a good 
assumption. At any contours, edges, or radii the electric field can grow 
considerably. This is basic electrostatics in operation. Just like the corona 
that happens at the end of antenna elements, where sharp edges occur, and is 
traditionally counteracted by increasing the radius of curvature (i.e. 
putting balls on the end).

       There are no doubt areas in the tube, possibly around the filament if 
it is a wound helix, which exactly fit the bill.
