METHODS FOR MEASUREMENT OF ULTRA-SHORT SINGLE-SHOT ELECTROMAGNETIC PULSES
Drexler, Petr ; Fiala, Pavel (advisor)
This thesis deals with the aspects of methods for pulsed high-level EM quantities measurement. Methods for current and voltage measurement in pulsed power generator and power measurement in pulse microwave generator are discussed. New approaches to single-shot measurement methods application are proposed. The theoretical analysis of suitable sensor designs is performed. The magneto-optic measurement method has been experimentally realized. On the basis of experimental results a fiber-optic current sensor has been designed and theoretically analyzed. For identification and measurement of the free-space electromagnetic pulse a combined calorimetric sensor has been designed and built.

Power impulse current sources
Nejedlý, Miroslav ; Fiala, Pavel (referee) ; Drexler, Petr (advisor)
This project deals with the probleme of the power pulsed current source. In this work, there is a study of some generators of pulsed current and than there has been made a design of power pulsed current generator. For the switching purposes the power switch based on the thyristor module has been designet. The advantages and disadvantages are discussen. The designed current source has been experimentally realized. The measurement of its parameters was performed.
