The polarized proton and deuteron beam at the Bonn isochronous cyclotron

Abstract

The present state of the polarized proton and deuteron source at the Bonn cyclotron is described. The source, which is of the atomic beam type, gives typical ion beam intensities of 2 ..mu..A for protons and 3 ..mu..A for deuterons. The overall transmission from the source to the first stopper after extraction from the cyclotron is 3%. Target currents with an energy resolution E/..delta..E=500 are 20 nA for deuterons and 10 nA for protons. For the proton beam, a polarization P=-0.71 was measured. For the deuteron beam, a pure vector polarization Psub(z)=-0.47 or various mixtures of vector and tensor polarization are obtained.
