FRPMN020 | Beam Profile Measurements Based on Light Radiation of Atoms Excited by the Particle Beam | 3955 |

Funding: Supported by BMBF and NRF, project-code SUA06/003 Diagnostics of intense particle beams requires development of new nondestructive beam monitoring methods. There are several kinds of diagnostic devices based on registration of products of accelerated beam particles interaction with atoms and molecules of residual gas in an accelerator vacuum chamber. Usually these devices used as beam profile monitors, which register electrons or/and ions produced in collisions of beam particles with residual gas. Some attempts were performed in application of light radiation of excited atoms. However, up to now this direction in the beam diagnostics was not developed properly. Nondestructive method of beam diagnostic system based on light radiation of atoms excited by the beam particles has the advantages - insensitivity to external magnetic and electric fields and, as a consequence, to the beam space charge fields. It allows to get higher spatial and time resolution. Measurements under different conditions at COSY-Juelich and in a cyclotron beamline at I'Themba LABS are presented and the pro and contra of the method is discussed |

The High-Energy Storage Ring (HESR) of the international Facility for Antiproton and Ion Research (FAIR) at GSI in Darmstadt is dedicated to Strong Interaction studies with antiprotons in the momentum range from 1.5 to 15 GeV/c. Powerful phase-space cooling is needed to reach demanding experimental requirements in terms of luminosity and beam quality. Status and details of technical planning including cryogenic concept will be presented. |
