We have sepetated the study in two steps, namely fundamental development of each technical items and practical usage of these items to achieve the goal of the project. Since various technical matters are related with generation of polarized slow positron-beams, we consider that the best way to complete the micra-beams of the polarized positrons is to make first precise studies of each component of the positron generation system :1) Understanding of spin motion in electric and magnetic fields.2) Generation of high intensity polaraized positron beams.3) Completion of beam vunching system.4) Development of the Wien filter.5) Establishment of the mesuring method for the positron polarization.6) Establishment of the mesuring method for p6sitron beam profile.7) Construction of multi-gamma-ray spectrometer.8) Study of production mechanisms of positorons.If these items are well understood, we will be able to construct the micra-beams of the polarized positrons without difficulties. It may be concluded that we have attained good results for all these matters. In particular, we achieved fur better results than initially expected.
