Photograph of cryogenic load frame, and ray diagram showing beam path: (a) vacuum vessel, (b) GM refrigerator, (c) loading driver, (d) vanadium windows, (e) aluminum windows, and (f) thermal shield.
Specimen setup: (A) specimen, (B) grip chucks, (C) thermal sensors, (D) extensometer, (E) strain gauges, and (F) aluminum thermal conductors.
Cooling performance measured at the GM cooler stage and grip chucks in the cryogenic load frame.
Neutron diffraction pattern and multi-peak analysis results at 7 K.
Thermal strain in type-304 stainless steel during cooling.
Lattice strain as a function of loading stress at 7 K. More than 10 peaks were chosen for the multi-peak analysis.
Lattice strain as a function of macro strain at 7 K. The lattice strains were obtained by the multi-peak analysis.
