Rf Recovery Using Cara and Depressed Collector*
نویسندگان
چکیده
A system is being tested for recovery of rf power by conversion to DC pulsed power. The system consists of a cyclotron autoresonance accelerator (CARA) [1,2], and a single stage depressed collector (Fig. 1). A 50 kV, 5 A electron beam is injected into CARA, and up to 1 MW of S-band rf power is absorbed by the beam with efficiency exceeding 95%. The beam then passes to a single stage depressed collector. RF to DC collection efficiencies of 73% are predicted but, due to collector breakdown above 125 kV, a maximum collector efficiency of only 41% has been observed to date.

3d Design of the Fusion-fem Depressed Collector Using the General Particle Tracer (gpt) Code
The “Rijnhuizen” Fusion Free-Electron Maser (FEM) is the pilot experiment for a high power, mm-wave source, tunable in the range 130-260 GHz. The FEM has generated 730 kW output power during 10 μs pulses. To increase the overall efficiency to over 50 % and to reach a pulse length of at least 100 ms, an electron beam charge and energy recovery system is currently being designed and installed. Th...

A four stage asymmetric type depressed collector has been designed for the Israeli mm-wave FEM that is driven by a 1.4MeV, 1.5A electron beam. After leaving the interaction section the spent beam has an energy spread of 120 keV and 75pmmmrad normalized beam emittance. Simulations of the beam transport system from the undulator exit through the decelerator tube into the collector have been carri...
متن کاملHigh Performance Lateral Schottky Collector Bipolar Transistors on SOI for VLSI Applications
Advanced bipolar transistors play a vital role in RF/Microwave applications. But they need to satisfy stringent demands on device performance parameters such as β, gm, and fT. Many of the bipolar technologies developed to meet these demands are vertical structures and suffer from many non−ideal effects at high collector current densities. In the present work, to enhance the performance limits o...
