To accurately measure neutron flux at several positions of small space inside assemblies in integral neutron experiments ,a micro plate fission chamber was designed and fabricated .Smaller volume and less struc-ture material were taken into consideration in the development of the detector .In this paper , the structure of fission chamber and process of fabrication were introduced and performance were tested and evaluated by meas -uring alpha spectrum from self -decay and fission spectrum .The detection efficiency of the detector was cali-brated and it is 91 .7%.The performance test results indicate that , the fission chamber has achieved the aimed parameter and goal , can be used in measurement of neutron flux .
