| Outline of Final Research Achievements |
The study of vacuum materials with very low outgassing properties is necessary to get 1E-11Pa to realize the electron gun for the high brightness synchrotron radiation source based on Energy Recovery Linac (ERL). In this study, the outgasiing measurement apparatus made of the titanium materials was developed. As for the conductance variableness mechanism of the main component of the system, it was demonstrated that operation according to design was possibility and that there was little outgassing. And in the developed system, the achievement of 1E-9 Pa was demonstrated. It was succeeded in the development of the measurement apparatus of outgassing rate with the very low detection limit of the order of 1E-13 Pam/s.
