| Research Abstract |
To reduce background in resonance ionization mass spectrometry applied for the failed fuel detection and location system of fast reactors, we developed a method of delayed ionization of krypton and xenon isotopes via the metastable states. With the use of a long wavelength laser for the delayed ionization, the effect of argon and argon dimer ionization on background generated by photoelectrons could successfully be eliminated, and the ionization efficiency was evaluated to be about 10% compared to that with a conventional technique of using a short-wavelength ultraviolet laser.
