In keeping with its continuing market expansion strategy, TMD Technologies Limited (TMD), world class West London based manufacturer in the microwave and RF field, will be showing a selection of its products for security applications on Stand P9 at Security & Policing 2017.
Exhibiting for the first time at IDEX, TMD Technologies Ltd (TMD), foremost West London based manufacturer in the microwave and RF field, will be showing a representative selection of its latest advanced products for air, land and sea defence applications.
Earlier this year TMD Technologies Limited (TMD), foremost West London based manufacturer in the microwave and RF field, received a major tube production contract that necessitated the construction of a brand new purpose built area for assembly, dress and test.
Abstract: This paper presents information about fast warm cathode for microwave tubes applications. Its mechanical profile and thermal characteristics are discussed.

Currently, electron beams are produced by heating a filament to the point where electrons have enough energy to overcome the work function. In field emission, the potential barrier is lowered by the strength of the applied field only.
Travelling wave tubes are vacuum devices with electron beams that couple to a microwave frequency electromagnetic signal (loosely termed ‘r.f.’ in the trade) propagating in the direction of the beam. Energy is transferred to the microwave signal, and the device generally behaves as an amplifier.
