| Outline of Final Research Achievements |
Mass spectrometry enables the measurement of mass of biomolecules. However, the measurable mass range is limited by the detector. On the other hand, the superconducting detectors have the detection efficiencies independent on mass of molecules. Among them, the superconducting strip particle detectors (SSPDs) realize the detection area as large as the diameter of a molecular beam and the response time as fast as nano seconds at the same time. In this study, the SSPD with the 100% detection efficiency along with 2 mm-square size and ns-response time has been realized for the first time. Consequently, by adjusting the applying bias current, it becomes possible to discriminate the charge of ionized molecules. The SSPDs are expected to be powerful detectors for the mass spectrometry of mixtures or other analytical instruments such as an atom probe.
