Neutron diffraction study in pulsed high magnetic field

We have developed a technique for neutron diffraction experiments in pulsed high magnetic fields to determine magnetic structures in high field. Our system is capable to produce pulsed fields up to 20 T every 2 sec. The experiment was done using MRP diffractmeter at KENS. The magnet was the so-called Bitter type water cooling solenoid with 40 mm inner diameter, 240 mm outer diameter and 220 mm length. It was horizontally installed on the goniometer. The flow type FRP cryostat was set in the magnet and the temperature was down to almost 4.2 K but there was a heating problem for metal sample when a pulsed magnetic field was applied. The first application has been done for a determination of high field magnetic structure of metamagnetic PrCo2Si2. (author)
