We would like to thank Dr. K. Imai at Kyoto University for joining the early stage of this work. We also wish to thank Prof. M. Kondo at the RCNP, Osaka University, for his interest and encouragements, the cyclotron crew for the invaluable assistance and Prof. I. Fujiwara at the Institute of Atomic Energy, Kyoto University, for suggesting a flexible graphite . The experiment of p-C elastic scattering was performed at the RCNP, Osaka University, under Program Numbers 17A05, 19C04, 19C12, and 21A03. This work was supported by Grants-in-Aid for Scientific Research nos. 58460016 and 60420007 of the Japan Ministry of Education, Science and Culture.

N2 - A new type of polarimeter has been built for protons between 20 and 84 MeV. It is a ray trace type with a multifoil of carbon, multiwire proportional chambers and plastic scintillators. The polarimeter distinguishes between elastic and inelastic scattering from carbon foil and has a large solid angle acceptance (∼ 470 msr) from the carbon foil. The effective analyzing power and the effective efficiency for practical use are estimated at 0.84 and 1.7 × 10-4 in the vicinity of 60 MeV, respectively. To evaluate these values, cross sections and analyzing powers for p-C elastic scattering have been measured for laboratory scattering angles between 15° and 80° at 19 energies from 21.1 to 83.8 MeV.
