EXPERIENCE WITH POLARIZED PROTON ACCELERATION AT COSY (JULICH).

PDF Version Also Available for Download.

Description

The Cooler Synchrotrons and storage ring COSY at the Forschungszentrum Juelich accelerates protons to momenta between 600 MeV/c and 3300 MeV/c [2]. At present the beam is used at four internal and three external target places. In addition, a polarized beam can be produced and accelerated at COSY. A colliding beams source, developed by a collaboration of the universities of Bonn, Erlangen, and Cologne is in operation [3]. The polarized H{sup {minus}} beam delivered by this source is pre-accelerated in a cyclotron to 295 MeV/c and injected via stripping injection into the COSY ring. The polarization of the circulating proton ... continued below

Description

The Cooler Synchrotrons and storage ring COSY at the Forschungszentrum Juelich accelerates protons to momenta between 600 MeV/c and 3300 MeV/c [2]. At present the beam is used at four internal and three external target places. In addition, a polarized beam can be produced and accelerated at COSY. A colliding beams source, developed by a collaboration of the universities of Bonn, Erlangen, and Cologne is in operation [3]. The polarized H{sup {minus}} beam delivered by this source is pre-accelerated in a cyclotron to 295 MeV/c and injected via stripping injection into the COSY ring. The polarization of the circulating proton beam in COSY is measured continuously during acceleration with the internal EDDA detector [4]. In this paper the methods to overcome depolarizing resonances in COSY are discussed and the progress to preserve polarization during acceleration is presented.
