| Outline of Final Research Achievements |
Gas ionization chamber with new electrode (coplanar electrode) was constructed and basic properties of the chamber was studied. Performance evaluation of energy resolution of the chamber as a function of shape of electrodes was studied. And the dependence of electronic noise on the detector capacitance was studied using an equivalent circuit. The experimental results show that the gas ionization chamber with coplanar electrode is appropriate to access low level environmental pollution.
