Research Abstract

In order to estimate H_2O isotope diffusion rate in ice sample, we developed equipment that applied laser ablation technique and mass spectroscopy. We designed and made a sample chamber for two-dimensional measurement of ice sample. The chamber is used for sample ablation, analysis, and vacuum by switching valves. It is connected to mass-spectrometer and ablated sample is measured using it. In the sample chamber, an ice sample vacuumed around 1 Pa is cooled by conduction using evaporated liquid nitrogen. Observation of the ice sample surface is success more than three hours. Evaporated sample is able to transport to mass spectrometer, however delay to detect isotope signal is present problem.
