The recirculating planar magnetron (RPM) [1] is a crossed-field device that combines the advantages of high-efficiency recirculating devices with the scalability of planar devices. Experiments using the RPM-12a, the first L-band prototype, have successfully produced 150 MW microwave pulses, 50-200 ns in duration, with instantaneous efficiencies of up to 30% at approximately 1 GHz [2]. The...

We describe a very Compact High Power Microwave system which is under development at CEA Gramat.
The electric pulses generation is provided by a compact and innovative 400 kV, 100 Hz Marx PFN. Its specific design provides a very fast rise time and its U shape agrees with severe geometry constraints.
A specific compact 45 kV capacitor charger for the Marx has been developed by...

This paper presents the design and operational characteristics of a compact, portable, high power microwave system. The system is capable of operating at various pulse repetition frequencies (PRFs) > 100 Hz for short bursts. The microwave source is tunable between 2-6 GHz with varying power. The system utilizes several main subsystems. These subsystems include a Marx generator, Marx air flow...

High Power Microwaves
Oral Presentation
Field emitter arrays have the potential to provide high current density, low voltage operation, and high pulse repetition for radar and communication. It is well known that packing density of the field emitter arrays significantly affects the emission current1. Previously we conducted experiments using two- and four-cathode configurations with same height. With all the fibers having uniform...

The paper describes the development of a repetitive 10 GW, Tesla-driven Blumlein pulsed power generator that produces a bipolar voltage output in excess of 600 kV peak-to-peak, with an initial rise time of about 300 ps and a frequency bandwidth larger than 1 GHz. The design of the system required PSpice simulations to be combined with three-dimensional analysis using the Computer Simulation...

Oral Presentation
Recent advances in the development of linear particle accelerators bring back new challenges regarding the design of pulsed power converters. On one hand, pulses quality (e.g. flat-top ripple, stability and repeatability) becomes more and more important because it directly influences the beam acceleration parameters. On the other hand, the need of reliable systems often requires a capacitor...
