Abstract

Parity violation in proton-proton elastic scattering provides a unique window on the hadronic weak interaction. At low and intermediate energies, the coupling constants of an effective meson exchange model provide an appropriate parametrization. Measurements at different beam energies permit the lowest partial wave amplitudes to be determined in a model independent framework. The TRIUMF cyclotron provides a unique opportunity to measure the ³P[sub 2]-¹ D[sub 2] contribution to proton-proton. parity violation at 221 MeV beam energy. This partial wave in turn isolates the weak ρ meson exchange contribution, which is only known to within a factor of 2 from theoretical estimates. An experiment underway for many years at TRIUMF completed data taking in 1999, and the analysis is now nearing completion. Preliminary results, based on half of the acquired data sample, are consistent with the meson exchange model prediction at this beam energy. [ABSTRACT FROM AUTHOR]

10. The application of the electron-cyclotron resonance source to Lamb-shift polarized ion sources

Author

Clegg, T.B., Schmor, P.W., Jacquot, G., Delaunay, M., Rocco, J.C., Geller, R., and Roy, G.

Abstract

We describe the application of an electron-cyclotron resonance ion source to a Lamb-shift spin-polarized ion sources. Initial experimental tests to measure the H−and D−ion current from such a system have not succeeded, probably because of large space-charge fields inside the beam which quenched desired 2S-metastable atoms within the ion source. However, a modified configuration is described which should eliminate these space-charge problems and is expected to yield substantially larger polarized H−and D−currents.
