Abstract

A Moebius loop magnetic field sensor is a circular loop consisting of two solid-shielded 50 ohms coaxial 'arms', which are split at the top to form a very small gap compared to the loop dimensions. The center conductor of each coaxial arm is connected to the shield of the opposite arm. The Moebius loop antenna can be used in very harsh environment conditions that occur during laser-target interaction (EMP and ionizing radiation). The laser and target chamber system is a high power (PW level) and ultrashort (tens of fs) laser beam, which heats the target inside the vacuum chamber (VC). The measurement system chain is constructed from 50 ohms of well-shielded coaxial cables between the Moebius loop antenna, an algebraic differential signal combiner (BALUN), and an oscilloscope protected at input through a high voltage pulse attenuator. Additionally, there are delay parameters (τ1, τ2; τ1 ≠ τ2) in time that characterize the cables' contribution between antenna and BALUN. There is a practical guideline that combines graphical information with analytical work to effectively study the local stability of models involving delay-dependent parameters. The stability of a given steady state is determined by the graphs of some function of τ1, τ2.
