| TUPRO042 | Ion Optics of the HESR Storage Ring at FAIR for Operation with Heavy Ions | 1117 |
|
||
| The High Energy Storage Ring (HESR) of the FAIR project is primarily designed for internal target experiments with stored and cooled antiprotons, which is the main objective of the PANDA collaboration. However, the HESR storage ring also appears to have remarkable properties to carry out physics experiments with heavy ions. In this paper a new ion optical design allowing the heavy ion operation mode of the HESR is presented. The main goal was to provide an optics which meets the requirements of the future experiments with heavy ion beams. Closed orbit correction, dynamic aperture as well as other characteristics of beam dynamics of the ion optical setup are under analysis in this study. | ||

| THPME101 | Considerations for a Cavity-Based Position-Sensitive Heavy Ion Detector for the CR at FAIR | 3477 |

Funding: Work funded by the European Commission (PITN-GA-2011-289485), the Alliance Program of the Helmholtz Association (HA216/EMMI), the Helmholtz-CAS Joint Research Group (HCJRG-108), the BMBF (05E12CD2). The Facility for Antiproton and Ion Research (FAIR) is a complex yet ongoing project which will allow for a broad range of experimental physics programs as well as a variety of material and medical applications. Being a heavy ion storage ring at FAIR, the Collector Ring (CR) is perfectly suitable for scientific investigations on fundamental properties – such as masses and lifetimes – of short-lived radioactive nuclei when it operates in isochronous mode. To fulfill stringent experimental requirements, a compatible heavy ion detector sensitive to beam intensities and positions is highly demanded. In this paper we present a conceptual design of cavity-based Schottky noise pickup to achieve non-destructive detections of stored particles. Computer-aided simulations follow immediately to justify the feasibility of such a design. |

| THPME122 | A SQUID-based Beam Current Monitor for FAIR | 3524 |
|
||
| A Cryogenic Current Comparator (CCC) was developed for the upcoming FAIR-Project, providing a non-destructive online monitoring of the beam current in the nA-range. The CCC was optimized for a lowest possible noise-limited current resolution together with a high system bandwidth. Therefore, the low temperature properties of ferromagnetic core materials used in the pick-up coil were investigated and different SQUID-systems were tested. In this contribution we present results of the completed Cryogenic Current Comparator for FAIR working in a laboratory environment, regarding the improvements in resolution and bandwidth due to the use of suitable ferromagnetic core materials and optimized SQUID-system components. | ||
