Title: A portable high-field pulsed-magnet system for single-crystal x-ray scattering studies

Abstract

We present a portable pulsed-magnet system for x-ray studies of materials in high magnetic fields (up to 30 T). The apparatus consists of a split-pair of minicoils cooled on a closed-cycle cryostat, which is used for x-ray diffraction studies with applied field normal to the scattering plane. A second independent closed-cycle cryostat is used for cooling the sample to near liquid helium temperatures. Pulsed magnetic fields ({approx}1 ms in total duration) are generated by discharging a configurable capacitor bank into the magnet coils. Time-resolved scattering data are collected using a combination of a fast single-photon counting detector, a multichannel scaler, and a high-resolution digital storage oscilloscope. The capabilities of this instrument are used to study a geometrically frustrated system revealing strong magnetostrictive effects in the spin-liquid state.

  • The defects-related microstructural features connected to the premartensitic and martensitic transition of a Ni{sub 2}MnGa single crystal under a high magnetic field of 50 KOe applied along the [1{bar 1}0] crystallographic direction of the Heusler phase were studied by the in-situ high-energy X-ray diffuse-scattering experiments on the high energy synchrotron beam line 11-ID-C of APS and thermomagnetization measurements. Our experiments show that a magnetic field of 50 KOe applied along the [1{bar 1}0] direction of the parent Heusler phase can promote the premartensitic transition of Ni{sub 2}MnGa single crystal, but puts off martensite transition and the reverse transition. The premartensiticmore » transition temperature (T{sub PM}) increases from 233 to 250 K (-40 to -23 C). The martensite transition start temperature (M{sub s}) decreases from 175 to 172 K (-98 to -101 C), while the reverse transition start temperature (A{sub s}) increases from 186 to 189 K (-87 to -84 C). The high magnetic field leads to a rapid rearrangement of martensite variants below the martensite transition finish temperature (M{sub f}). The real transition process of Ni{sub 2}MnGa single crystal under the high magnetic field was in-situ traced.« less
  • We have developed a pulsed magnet system with panoramic access for synchrotron x-ray diffraction in magnetic fields up to 31 T and at low temperature down to 1.5 K. The apparatus consists of a split-pair magnet, a liquid nitrogen bath to cool the pulsed coil, and a helium cryostat allowing sample temperatures from 1.5 up to 250 K. Using a 1.15 MJ mobile generator, magnetic field pulses of 60 ms length were generated in the magnet, with a rise time of 16.5 ms and a repetition rate of 2 pulses/h at 31 T. The setup was validated for single crystal diffraction on the ESRF beamline ID06.
  • A versatile system, operating at pressures to 300 MPa and temperatures to 4 K, has been designed and used for a variety of elastic and inelastic x-ray scattering studies of single crystals of condensed gases. Sintered Be sample cells of volumes 15{endash}30 mm{sup 3} are used. Pressure generation is clean and well controlled. Excellent temperature control allows monitoring of phase transitions associated with solidification and melting. The system has very low background and, combined with the high-intensity of synchrotron radiation, is well suited to studies of low-intensity signals. It has been used for {sup 4}He in {ital q}-dependent studies ofmore » fcc lattice dynamics and diffuse scattering and to study thermal defect properties through lattice parameter measurements. In addition, its application to inelastic scattering studies of hcp {sup 4}He at 1.5 eV and 10 meV resolution have yielded results about electronic and phonon excitations, respectively. The system can also be used to study other crystalline compounds; in particular, an application has been made to lattice parameter measurements on C{sub 2}F{sub 6}. {copyright} {ital 1996 American Institute of Physics.}« less
  • In tokamak fusion reactors, plasma is inductively heated by pulsed magnets. Designs of pulsed magnets with higher magnetic field were recently introduced aiming at long pulsed operation, which reduces the heat load in the reactors and makes them compact. In this paper the authors have been developing a new type of Nb{sub 3}Sn superconductor, a Fiber-Reinforced-Superconductor (FRS), to make an attempt at the application of high-field pulsed superconducting magnets. FRSs have high elastic modulus fibers such as tungsten so that the strain on superconducting layer caused by hoop stress can be reduced. Such high elastic modulus materials however, tend tomore » have lower thermal expansion coefficient compared with Nb{sub 3}Sn. The resultant tensile prestrain on Nb{sub 3}Sn at liquid helium temperature brings about the degradation of superconducting characteristics. In this paper, it is shown that the strain characteristics of FRS can be largely improved by adopting a tungsten alloy, keeping high elastic modulus of pure tungsten.« less
