High-Energy Electron Cooling at Lear pp̄-Collider
A low energy pp̄-colliding beam facility was proposed some time ago.1 The pp̄-collision option was presented in the “Design study of a facility for...,”2 where LEAR is conceived as a minicollider; this facility covers a center-of-mass energy range from 2.3 to 4.4 GeV. From the minicollider scheme, we can see that the evaluated luminosity is not sufficient to perform the whole physics program proposed.1 An efficient method of increasing the luminosity consists of cooling both pp̄ beams continuously with a high-energy electron cooling device,3 working in the wide momentum range foreseen for the collider mode.
