SLAC: electrons from 42 GeV to 84 GeV in one meter

Electrons accelerated to 42 GeV by SLAC entered a 33-inch long lithium plasma chamber with waves that changed the energy of the electrons in different ways: some electrons lose, other electrons gain. The happy ones ended up with 84 GeV. This method, based on a firm rejection of the egalitarianism of electrons, may lead to some really powerful accelerators in the future. See
