چکیده
A model of a squeezer has been built and experiments are being made (see Fig. VIII-1). A 10-kv pulsed shielded cathode gun of perveance 106 is used to form the beam. The output cavity is very heavily loaded so that it can be used as an "ammeter" (low-impedance) to measure beam current. A polystyrene double-slug tuner allows us to vary the gap impedance over a range of approximately 36:1. The best efficiency obtained thus far has been approximately 30 per cent; but there was a strong multipactor discharge in the output cavity at this power level. The present effort is aimed at eliminating the multipactor discharge so that the true limiting efficiency can be determined. L. D. Smullin, S. Holly

Our major research objective is the same as it has been for many years, although it has not been previously stated explicitly. First, we attempt to discover fundamental performance limits to be placed on functions performed by solid-state devices, in terms of the technological and physical parameters of the devices. Second, we attempt to provide the necessary circuit imbeddment procedures to re...

In Quarterly Progress Report No. 80 (page 99) a method was discussed for extracting information on the velocity distribution of electrons in a plasma from measurements of the spectrum of emitted microwave radiation. Briefly, in the neighborhood of wB' the electron cyclotron frequency of an applied magnetic field, the departure of the effective radiation temperature, Tr(w), from a constant value...
متن کاملLow Power Superconducting Microwave Applications and Microwave Microscopy
We briefly review some non-accelerator high-frequency applications of superconductors. These include the use of high-Tc superconductors in front-end band-pass filters in cellular telephone base stations, the High Temperature Superconductor Space Experiment, and high-speed digital electronics. We also present an overview of our work on a novel form of near-field scanning microscopy at microwave ...
