EN The paper deals with a magnetostrictive fast-acting actuator applied as a driving device for plasma valve designed for so called “high intensity plasma pulses gun”. The actuator is characterized by a small displacement, but with a very short response time – below 0.1 ms. A structure with an axisymmetrical actuator energised by discharged pulses of a capacitor has been proposed. The field-circuit mathematical model of the dynamic operation of the actuator has been applied. The model includes: the equation of transient electromagnetic field in a non-linear ferromagnetic material and equation of electric circuit. The computer software has been elaborated. Results of simulation are presented.
