This apparatus is composed of an electrostatic levitator, a neutron inlet path with Cd slit, a 160 deg window to detect scattered neutrons, a CO2 laser for sample heating, and an optical pyrometer for temperature measurements. A preliminary neutron diffraction experiment with this ESL was performed with polycrystalline alumina samples. The sample position could be controlled with an accuracy of +/- 0.1 mm. The observed Bragg peaks were in complete agreement with those derived from the lattice data of alumina obtained from the literature. This indicates that this facility is effective for the structural study of condensed matter without containers., 資料番号: AA0045399003, レポート番号: NASDA-TMR-020025E}, title = {Development of an electrostatic levitator for neutron diffraction structure analysis}, year = {2002} }
