Laser cooling of relativistic C ions at the ESR
Recent experiments [1,2] at the Experimental Storage Ring (ESR) at GSI have shown that relativistic Li-like carbon (C) ion beams can be laser-cooled to an unprecedented momentum spread of p/p 10. Here, a single-frequency laser was tuned to the Doppler-shifted 1s2s 1s2p (P1/2 and P3/2) transitions. These results encourage the application of laser cooling to beams of other Liand Na-like ions at e...
متن کاملLaser Cooling and Spectroscopy of Relativistic C 3 + Beams at the ESR ∗
We report on the first laser cooling of a bunched beam of multiply charged C ions performed at the ESR (GSI) at a beam energy of E = 1.47GeV. Moderate bunching provided a force counteracting the decelerating laser force of one counterpropagating laser beam. This versatile type of laser cooling lead to longitudinally space-charge dominated beams with an unprecedented momentum spread of ∆p/p ≈ 10...
متن کاملInternal Target Effects in the Esr Storage Ring with Cooling
The accurate description of internal target effects is important for the prediction of operation conditions which are required for future experiments in the storage rings of the FAIR facility at GSI. A number of codes such as PTARGET, MOCAC, PETAG01 and BETACOOL have been developed to evaluate the beam dynamics in the storage ring, where an internal target in combination with an electron coolin...
متن کاملOptical stochastic cooling.
In this paper, we consider the utilization of optical amplifiers with bandwidth ∆f ∼= 1014Hz for use in stochastic cooling. It is shown that quadrupole and dipole wigglers can be used as pickups and kickers respectively. The proposed method increases the application of the stochastic cooling method beyond the traditional area of proton-antiproton cooling. For example, the method can also be app...
متن کاملPick-Up and Kicker Electrodes for Stochastic Cooling at FAIR
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 elec...
