A compact research facility for pulsed high magnetic fields of up to 50 T

摘要

A facility for generating pulsed magnetic fields with a millisecond duration and maximum peak values of 50 T is presented. The solenoid is produced from a Cu-Nb microcomposite conductor and is reinforced with a bandage made from Armos para-aramid fiber. The capacitor bank is switched to the high magnetic field solenoid by means of a solid-state switch board based on a module of reversely connected dynistors. Since the diameter of the working hole is 19.5 mm, it is possible to place a cryostat in it with operating temperatures as low as the helium temperatures and to measure the magnetization, the complex conductance, and the optical characteristics of substances in the visible and IR ranges. The operation features of the facility are discussed.
