The waveguide must be pressurised to a minimum pressure of 35 ib/in2 absolute to prevent waveguide breakdown and to provide cooling air across the valve output window.

A cooling pipe is attached alongside the single connecting lead. This appears to blow onto the glass stem, exiting the other side through a hole. It also appears to form one connection.

Cooling fins Window
On one side is an aperture leading to cooling fins, on the other a waveguide aperture.

The glass stem. The number 34385 is marked on the inside structure.
