By analogy with the kinetic theory of gases where heat is equivalent to disorder, the term "cooling" designates the reduction of the beam's transverse dimensions and energy spread Different techniques can be used to this effect Electron cooling, more effective at low energy, uses an electron beam merged with the antiproton beam, and acts as a heat exchanger between the two beams In the case of stochastic cooling, an error signal generated in a monitor is fed back, via a corrector, to the beam sample which created it, eventually centering the sample's characteristics towards the average value, after a large number of passages through the apparatus
