Abstract

There are some suitable methods for the measurement of ultra-short solitary electromagnetic pulses that can be generated by high power pulsed generators. The measurement methods properties have to correspond to the fact whether we want to measure pulses of voltage, current or free-space electromagnetic wave. The need for specific measurement methods occured by the development of high power microwave pulse generator [1]. Applicable methods are presented in this paper. The method utilizing Faraday's induction law allows the measurement of generated current. For the same purpose the magneto-optic method can be utilized, with its advantages. For measurement of output microwave pulse of the generator, the calorimetric method was designed and realized.

Summary

Introduction

Shows the basic principle of microwave pulsed power generator. After transformation to the high voltage and pulse shaping (not shown in Fig. 1), the pulse is fed to the microwave pulsed power generator. The peak level of current pulse achieves the value of Ip = 100 kA with the pulse duration td = 70 μs typically in the second stage. After high voltage transformation and using pulse shaping element we can get a voltage pulse with the peak value Up = 400 kV and with the rise time tr = 0.1 ns.
