A 500-kV photocathode DC electron gun which can supply the beam of a low emittance and a high average current has been developed in collaboration with KEK, JAEA, Hiroshima Univ., Nagoya Univ. and Yamaguchi Univ. The vacuum of the gun chamber has to be lower Extreme High Vacuum for maintain cathode-life time. A titanium chamber and new material of ceramic were employed to reduce outgassing rate. The result of outgassing rate of the gun chamber is described in this report.

An electric quadrupole moment ( moment) is sensitive to collective aspects of nuclear structure. In the -moment measurement for unstable nuclei, we employ the -detected nuclear-quadrupole resonance method. In this method, we need to supply resonance frequencies, where denotes the nuclear spin. We have developed a new RF-application system to induced all of the transitions. The application of the frequencies may be pursued in two different ways; the sequential RF pulse method and the mixed-wave RF pulse method. We confirmed the reversal of polarization for the both methods, from measurements of -ray asymmetry change for polarized B. Using this system, the moments of Al have been measured to be mb and mb by the sequential RF pulse method.
