Outline of Final Research Achievements

In this study, We explored the feasibility of radiation position detector by using Tungsten wire mesh as an anode electrode plane which can produce lower cost compared to existing detectors. The 30 mesh/inch by 30 um wire was selected as an anode electrode after electrical calculation, discharge test. The operation has checked by observing the signal synchronized with the scintillator. However, the stable operation for the discharge was examined by the electric field calculation how to improve because it did not reach stable condition.
