Optical 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 کاملKink instability suppression with stochastic cooling pickup and kicker
The kink instability is one of the major beam dynamics issues of the linac-ring based electron ion collider. This head-tail type instability arises from the oscillation of the electron beam inside the opposing ion beam. It must be suppressed to achieve the desired luminosity. There are various ways to suppress the instability, such as tuning the chromaticity in the ion ring or by a dedicated fe...
متن کاملStochastic cooling of atoms using lasers
We propose a method to laser-cool atoms based on stochastic cooling, first developed at CERN to cool antiprotons. Fluctuations in the momentum distribution will be detected in a pump-probe configuration with far-detuned lasers, and the appropriate correction kick will be accomplished with optical dipole potentials. Each stage of an iterative cooling process will involve measurement and feedback...
متن کاملStochastic cooling and the accumulation of antiprotons.
1. A general outline of the pfi project The large project mentioned in the motivation of this year’s Nobel award in physics includes in addition to the experiments proper described by C. Rubbia, the complex machinery for colliding high-energy protons and antiprotons (Fig. 1). Protons are accelerated to 26 GeV/c in the PS machine and are used to produce p’s in a copper target. An accumulator rin...
متن کاملStochastic processes in muon ionization cooling
A muon ionization cooling channel consists of three major components: the magnet optics, an acceleration cavity, and an energy absorber. The absorber of liquid hydrogen contained by thin aluminum windows is the only component which introduces stochastic processes into the otherwise deterministic acceleration system. The scattering dynamics of the transverse coordinates is described by Gaussian ...
