A SOURCE OF POLARIZED DEUTERONS AND DETECTION OF POLARIZATION IN THE (d,T) REACTION (in German)
The design, construction and test of a source of polarized deuterons are dsscribed. Three hyperfine components of an atomic deuterium beam are separated in a strong magnetic quadrupole field. The beam then passes into a weak homogeneous field, where the atoms are ionized by electron bombardment. The gas kinetics of the formation and the polarization of the beam are discussed together with the attendant technical problems of magnetic fields and vacuum. The atomic beam intensity is predicted from theory and compared with the measured value. The ionization of the atomic beam and the resulting deuteron polarization are described. Calculations of the spin populations of the ion beam and the resulting polarization are given. The tensor polarization of the beam is measured with the T(d,n) He/sup 4/ reaction. The beam consists of 10/sup -8/ A of deuterons characterized by P/sub 33/ = -0.245. Experiments indocate the usefulness of the device as a source of polarized protons, if the proton content of the residual gas is reduced. (auth)
