High power microwave switch employing electron beam triggering with application to active rf pulse compressors

Active RF Pulse Compression Using Electrically Controlled Semiconductor Switch

First we review the theory of active pulse compression systems using resonant delay lines. Then we describe the design of an electrically controlled semiconductor active switch. The switch comprises an active window and an overmoded waveguide three-port network. The active window is based on a four-inch silicon wafer which has 960 PIN diodes. These are spatially combined in an overmoded wavegui...

High Power X-band Semiconductor Rf Switch for Pulse Compression Systems of Future Linear Colliders

We describe the potential of semiconductor X-band RF switch arrays as a means of developing high power RF pulse compression systems for future linear colliders. We describe design methodology of high power RF switches, and scaling law which governs the relation between power handling capability and number of elements. The design and implementation of the active waveguide window is presented. Th...

Microwave growth from the beam breakup instability in long-pulse electron beam experiments

The beam breakup (BBU) instability has been investigated in high-current, long-pulse electron beams propagating through microwave cavities. Experiments are performed using a relativistic electron-beam generator with diode parameters: 0.7-0.8 MV, 1-15 kA, and OS-l.5 ps. The magnitude of the solenoidal magnetic field places these experiments in an intermediate regime between strong focusing and w...
