The problem of generating powerful pulses of magnetic field with amplitude stabilization at the INGIRMega-15 facility is considered. The aim of the work is to develop a technique for calculating the parameters of an induction sensor for high-power magnetic field pulses based on reed switch and experimental verification of the theoretical estimates obtained. The value of the induction of the magnetic field at a point remote from the solenoid by a given distance is found. The time of contact closure of reed contact is determined. In the process of experiments, oscillograms of solenoid current signals, the voltage on it and trigger signal of reed switch are taken. The feature of the method studied is the possibility of obtaining a stable amplitude of the magnetic field pulse due to feedback through reed switch, which contributes to the improvement of technological cycles frequency, for example, in the detonation sputtering of metal.

Key words: generator, high-voltage vacuum solenoid contact, reed switch, capacitor bank, fieldgenerating system, solenoid, pulsed magnetic field, circuit time.
