Overview

Thermal Desorption Spectrometry (TDS) is a device which heats and raises the sample in a high vacuum container, and detects the gas component by the quadrupole mass spectrometer (QMS).

The characteristics of the TDS owned in our laboratory has the following two points:

• Because the heating rate range is from room temperature to 1800℃ measurement in a wide range is possible.
• High resolution QMS has been developed for separative measurement of deuterium (mass number: 4.0282) and helium (mass number: 4.0026).

By combining with other plasma irradiation devices, we are investigating plasma-material interaction.
