Outline of Final Research Achievements

The cryostat was developed on the basis of a GM refrigerator to investigate the surface melting of a solid hydrogen (H2) film by time-of-flight secondary ion mass spectrometry (TOF-SIMS). As a result of those development, a new sample cooling manipulator was successfully developed, by which a sample can be flashed for surface cleaning in UHV. The newly developed sample manipulator was used in temperature programmed TOF-SIMS measurements on a solid hydrogen film. We found that the remarkable variation of the secondary ion emission occurs due to the re-crystallization and the melting on the topmost surface. Thus, TOF-SIMS may be applied to analyze the phase transition on solid surfaces.
