Number 185 (Story #4), June 28, 1994 by Phillip F. Schewe and Ben Stein A 75-NANOMETER-WIDE ELECTRON BEAM has been produced at the Stanford Linear Accelerator Center. With the next generation of linear colliders moving from the GeV to TeV energy range, more tightly focused beams are crucial so as to maximize the likelihood of high- energy collision events between particles. The narrow beam, demonstrated at the SLAC's Final Focus Test Beam (FFTB) facility just a month after it became operational, already approaches the FFTB group's goal of a beam with vertical width of 60 nanometers and horizontal width of a micron.
