What is this "centre anode " part? >From my limited understanding the W grid is a heated cathode and the Sputtered Copper housing is the Anode.
Although there was originally some attemp to run a cathode - anode pulsed or wave form signal this seems to have been abandoned in favour of a pulsed heating current to the cathode. Was The MAHG ever built as a triode ? My understanding of a triode is that it had a separate plate in the ion stream to modify the output to the anode. this doesn't appear to have ever been the case. One measurement that doesn't seem to have been made and would be interesting is the differential from cathode to anode and if there is an excess of electrons being carried across in the hydrogen stream. I think tungsten was chosen in the original tube because it is an excellent electron emitter and this effect doesn't appear to have been measured in the MAHG.
