Stroboscopic Time-of-Flight Neutron Diffraction in Long Pulsed Magnetic Fields

Taro Nakajima, Masao Watanabe, Yasuhiro Inamura +9

We present proof-of-principle experiments of stroboscopic time-of-flight (TOF) neutron diffraction in long pulsed magnetic fields. By utilizing electric double-layer capacitors, we…
