英语翻译
A Nd:Yag laser based laser-heating system is used in this study.The laser is microfocused to heat the sample at approximately 30 degree from the normal direction to the sample.Thermal emission is collected by a chromatically corrected objective (x20) at about 15 degree from the vertical direction.A pin-hole is used to limit the field of view within 4 pm at the center of laser heated area and a single-core 200μm optical fiber is used to deliver thermal emission from the pinhole to a spectrometer coupled with a liquid nitrogen cooled CCD detector.The temperature is then determined by the fitting of thermal emission to a gray-body radiation equation.
High intensity focused monochromatic x-ray,diffracted from Si (220) at 20 KeV,is available at the beamline 10-2 of Stanford Synchrotron Radiation Laboratory (SSRL).The synchrotron x-ray
is coaxially alined at the center of laser-heating spot.The x-rays dffracted from the sample are angle-resolved by using an imaging plate.The imaging plate is typically set at the distance
approximately 200 cm apart from the sample,which can record the diffraction pattern Up to XI=45 degrees.The pathway of direct x-ray is covered with He-circulating tubes to minimize the
background exposure on the imaging plate dector.A small
adjustment of the diamond anvil cell is sometimes needed to reduce the multiple reflections arising from stong single crystal diamond diffraction lines
