Abstract :
A polarimeter which utilizes ortho-positronium quenching in a magnetic field is used to measure polarization of slow positron beams. This polarimeter is employed for a polarization measurement at an e+ beam system where the beam is provided from the β+ decay of 27Si produced via the 27Al(p,n)27Si reaction caused by proton irradiation. The beam polarization is determined to be 38.4±4.0(statistical)±8.7(systematic)%.
