Pick-Up and Kicker Electrodes for Stochastic Cooling at FAIR
نویسندگان
چکیده
The main task of the FAIR collector ring (CR) is stochastic cooling of rare isotope beams (RIBs) with β = 0.83 and antiprotons (p̄) with β = 0.97. The CR should achieve a phase space volume reduction of 1.6 · 10 in 5 s for p̄ and 1.3 · 10 in 1 s for RIBs. To fulfill this, the pickups must have a large bandwidth and a high S/N ratio in spite of the large aperture of 120 · 120 mm. A new planar electrode is developed [2] to meet these requirements.

Planar Pick-Up Electrodes for Stochastic Cooling at the FAIR Project
The collector ring (CR) of the proposed facility for antiproton and ion research (FAIR) includes a fast stochastic cooling system for exotic nuclei with β = 0.83 and antiprotons with β = 0.97. For fast cooling, a good S/N ratio of the pick-up is crucial. The large initial emittances lead to the requirement of covering a large aperture (typically 200 mm). The λ/4-loop electrodes, currently used ...

Supported in part by DFG under contract GraKo 410 and GSI, Darmstadt Stochastic cooling will be an important issue in the new GSI project. Crucial to the efficiency of stochastic cooling is an ideal coupling to the beam. The main coupling elements are pickup/kicker electrodes. These electrodes have to be analysed and optimised extensively. The optimisation is performed by a three dimensional nu...
