6-ID-C Station

6-ID-C is focused on diffraction studies in magnetic fields. A cryogen-free 4.5 Tesla superconducting (SC) magnet and a 30 Tesla pulsed-field (PF) magnet are available. References below can be consulted for details of resonant and non-resonant scattering studies, instrument capabilities, and scientific areas explored. Scattering experiments spanning an x-ray energy range of 7-30 keV have been performed. Magnetic field and temperature ranges routinely available are listed in the following table:

Field and Temperature           Techniques Comments

4.5 to 325 K

4.5 Tesla (SC magnet)
  • Single-crystal diffraction
  • X-ray resonant exchange scattering
  • Non-resonant magnetic scattering
  • Polarization analyzer is typically a PG crystal
  • Ge or Si analyzers used for high-resolution diffraction

6.0 to 300 K

30 Tesla (PF magnet)
  • Single-crystal diffraction in transmission geometry (scattering angle <23 degrees)
  • Diffraction in back-reflection geometry (scattering angles between 158 and 175 degrees)
  • High-resolution structural studies take advantage of back-reflection set-up
  • Typical sample is thin plate-like with a linear dimensions of 0.5-2.0 mm

 
Magnet Diffractometer

(a) Nano-calorimeter; (b) 4T SC split-pair magnet; (c) He-4 VTI

There are ongoing R&D efforts to use nano-calorimetry concurrently with x-ray scattering in 4 Tesla superconducting magnet. (a) Calorimeter on cryostat cold finger together with optical microscopy images of the nanocalorimeter cell and a sketch of the chip. A thermometer and an offset heater allow one to control and stabilize the temperature of the sample, while the ac heater enables specific heat measurements. (b) Diffractometer with split-pair magnet mounted. The nanocalorimeter is attached to the tip of a cold finger helium flow cryostat (c), which is inserted inside the superconducting split-pair vertical-field magnet resulting in a magnetic field parallel to the membrane.
