The purpose of our study is to develop a Spin-Polarized Atomic Hydrogen Beam (SPH), and apply it to surface science studies. Molecular hydrogen is dissociated into atoms by 2.45 GHz microwave discharge and the spin of the hydrogen atoms is selected by using a hexapole magnet to obtain SPH. In this presentation, we will discuss the result of the measurement of the spin polarization of SPH by using the Stern-Gerlach magnet and the calculation of the beam trajectory of SPH.
