A spin-polarized slow positron beam is generated by a sodium-22 source and a solid Krypton moderator and transported to the sample chamber by electrostatic lenses. Incident energy is adjusted by a retarding potential using a deceleration tube. For the lifetime measurement, the start signal is obtained from a secondary-electron detector installed in front of the sample. The stop signal is detected by a scintillation detector for annihilation gamma ray. As the performance test, Ps lifetime measurements were carried out and clear decay curves derived from ortho-Ps self-annihilation were successfully observed. This system might be used for the estimation of the spin polarization at the surface of the ferromagnetic materials.
