Abstract:

The work is aimed at investigating the feasibility of achieving low noise microwave amplification by using tunneling. At present it is possible to build tunnel cathodes that exhibit sufficient current density to permit their use in a traveling wave tube. However, the life of the cathodes under both continuous and pulsed operation is by no means satisfactory. For this reason the efforts are primarily aimed at investigating the life and stability of the devices. The experimental work consisted primarily of 1 fabrication of tunnel cathodes using mainly methods developed in the previous contract, b investigation of the life and stability of these devices in continuous operation under both dc and ac conditions, and c investigations of the low noise properties of the tunnel cathode involving dc measurements near the threshold of emmission.
