| Research Abstract |
We completed preparations toward operation of the polarized proton target from irradiated-ammonia to the stage where we can achieve with currently available equipments at KEK. The superconducting magnet was successfully excited, and thermal equilibrium signals of fluorine in the Teflon and proton in the polyethylene beads were observed. We have also advanced development of polarized-target materials with irradiated polyethylene fibers and foils at Yamagata University. The polyethylene samples were irradiated with electron beams to make polarized-target materials, and the spin density of the irradiated samples were measured precisely with the ESR.
