マルチアンビル装置を用いた高温高圧X線その場観察実験における圧力測定の誤差

抄録

Accurate measurement of pressure is fundamental in high-pressure and high-temperature research. To make better measurements, it is important to identify error sources and their seriousness. Error sources in synchrotron X-ray-diffraction multi-anvil experiments, such as non-hydrostatic stresses, pressure effects on e.m.f. of thermocouples, uncertainties in pressure scales, etc. are reviewed.
