A compact 30 T magnetic field platform for magnetized high-energy-density plasma research*

A pulsed high magnetic field device based on inductively coupled coil concept is described.
The device generates a pulsed magnetic field of up to 30 T inside a single-turn coil with an inner diameter of 6.5 mm and a length of 6.3 mm.  The magnetic field is created by discharging a high-voltage capacitor through a multi-turn solenoid, which is inductively coupled to a small single-turn coil.  The solenoid electric current pulse of tens of kA and a duration of several  ${\mu}$s is inductively transformed to hundreds of kA in the single-turn coil, thus enabling a high magnetic field.  The inductively-coupled system operates using a relatively low-current power supply with very relaxed requirements for its inductance.   This arrangement significantly simplifies the design of the power supply and also makes it possible to place the power supply at a significant distance from the coil.  In addition, the  device is designed to contain possible wire debris, which makes it attractive for debris-sensitive applications.
