Stochastic cooling overview

Abstract

The status of stochastic cooling and developments over the years are reviewed with reference to much of the original work. Both theoretical and technological subjects are considered.

History of stochastic beam cooling and its application in many different projects

“…Lattice parameters are especially important for the achievement of 'good' values of M , and U , maximising the bracket in equation (3). In addition to the struggle for large bandwidth, the advance in stochastic cooling is intimately linked to progress in dealing with the noise and mixing factors.…”

“…Beam cooling [1][2][3][4] aims at reducing the size and the energy spread of a particle beam circulating in a storage ring. This reduction should not be accompanied by beam loss; rather the goal is to increase the particle density.…”

Measurement of electroweak single top quark production in proton-antiproton collisions at 1.96 TeV

“…While the antiprotons stay in the Accumulator, they are "cooled," reduced in transverse momentum, through a process called stochastic cooling [33]. This procedure measures the momentum spread of a group of antiprotons and sends a signal across the ring to corrector magnets, which adjust their fields for each group of particles to reduce the momentum spread of those particles.…”

Simulation free measurement of the B⁺ → $\bar{D}$⁰π⁺ lifetime using decays selected using displaced tracks

“…Through the interaction spread is essential to maintain efficient transfer of the beam to subsequent accelerators. Stochastic cooling processes [29] are applied to cool the transverse energy, which…”
