PLASMA DIAGNOSTICS WITH SHORT ELECTROMAGNETIC PULSES

Description: The propagation of short electromagnetic pulses in an ionized medium and the reflection of transient pulses from bounded ionized regions is discussed. Analyticai expressions for transient oscillations in reflected and propagated electromagnetic fields excited by a unidirectional pulse are derived for certain simple cases. The transient oscillations show a periodicity that is directly related to the plasma frequency and are useful for nearly instantaneous plasma diagnostics. An experiment is des… more

Physical Limitations on the Measurement of Transient Fields in Air and in Dissipative Media Using Electric and Magnetic Probes

Description: The properties of electric and magnetic probes for the measurement of transient electromagnetic fields in air and in dissipative media are discussed briefly, It is shown that the effective height of an electrically small loop is independent of the ambient medium. This is also virtually true for a thin electrically short dipole (or monopole). If the open-circuit voltage of a magnetic probe can be measured accurately, it is possible (in principle) to reconstruct the time history of the incident m… more

Experimental Studies on the Current Carrying Capacity of NbZr Wires Under Conditions of Fixed and Swept Magnetic Field

Description: Abstract: The current-carrying capacity of Nb- Zr wire has been studied under conditions of swept magnetic field and fixed wire current and of fixed magnetic field and swept wire current. The effects of wire movement, thermal environment, copper coating of the wire, and rate of sweep of wire current or magnetic field have been determined for these conditions of test.
