Standard Reference Material (SRM 1990) For Single Crystal Diffractometer Alignment
An international project was successfully completed which involved two major undertakings: (1) a round-robin to demonstrate the viability of the selected standard and (2) the certification of the lattice parameters of the SRM 1990, a Standard Reference Material(®) for single crystal diffractometer alignment. This SRM is a set of ≈3500 units of Cr-doped Al2O3, or ruby spheres [(0.420.011 mole fr...
متن کاملTorsion / Simple Shear of Single Crystal Copper
We analyze simple shear and torsion of single crystal copper by employing experiments, molecular dynamics simulations, and finite element simulations in order to focus on the kinematic responses and the apparent yield strengths at different length scales of the specimens. In order to compare torsion with simple shear, the specimens were designed to be of similar size. To accomplish this, the ra...
متن کاملMagneto-Optical properties of GaP single crystal
The temperature dependence of magneto-optical and magneto-photoconductivity measurements were carried out in the range of (200-330) K. A home made optical cryostat was used for the measurements. The measured room temperature value of the energy gap was found to be 2.211 eV. The temperature coefficient of energy gap was found to be -5.48×10-4 eV/K obtained by the optical absorption method and -4...
متن کاملPyroelectric Crystal-Based X-Ray Diffractometer by
We investigate the use of an Amptek Cool-X X-ray Generator for an instructional tool in the physics of x-rays, as well as a source for x-rays for crystal diffraction experiments. The x-ray source is a solid-state two-phase air-cooled source with a timevarying photon output. Two detectors are used in this experiment, the first being an Amptek X-123 Spectrometer and the second a combination scint...
متن کاملEFFECT OF SPIRAL DESIGN ON CRYSTAL ORIENTATION DURING SINGLE CRYSTAL GROWTH
Geometrical design of the spiral crystal selector can affect crystal orientation in the final single crystal structure. To achieve a better understanding of conditions associated with the onset of crystal orientation in a spiral crystal selector, temperature field was investigated using three-dimensional finite element method during the process. Different geometries of spiral crystal selec...
