The discovery of the point–like structure of matter
About 30 years ago, experiments began to confirm the hypothesis that protons (and the other hadrons) could be treated as composites of much smaller ‘point–like’ elements. Electron–proton scattering experiments at the Stanford Linear Accelerator Center played a prominent role in the shifting view of hadron structure. In this paper, I have tried to convey some flavour of our experimental efforts and our interactions with theorists both before and during the experiments.

POSITIVE PION PRODUCTION BY POLARIZED BREMSSTRAHLUNG
By selecting bremsstrahlung produced in a 0.003-in. aluminum radiator at a small angle from the original electron direction, a beam of polarized bremsstrahlung has been obtained from the Stanford linear accelerator. The variation of the polarization and intensity with angle was studied and compared with theoretical predictions. The polarized beam has been used to study pi /sup +/-meson production at 90 deg c.m. angle and photon energies of 242, 296. 337. and 376 Mev. The ratio of meson production along and at right angles to the electric field vector has been measured and compared wiih the values predicted by the relativistic dispersion relation. (auth)

An historical review of lepton proton scattering
In this talk I will try to review some of the early experiments in the field of electron-proton scattering, concentrating mostly on the inelastic scattering experiments at SLAC. Ordinarily, those experiments would be covered in the first five or ten minutes of the talks by Professor Scuilli and Drell, but this is a special year, and I will feel free to reminisce about the early days in a somewhat personal way.

MAGNETIC MEASUREMENTS OF QUADRUPOLE FOCUSING MAGNETS AT SLAC*
\ A rotating coil technique was used to find the m gnetic centers of l?r quadrupole magnets used in the final focus of high en gy-electron and positron beams in the SLAC Linear Collider at the Stanford Linear Accelerator Center. These methods provide interesting applications of classical electromagnetic theory for use in the undergraduate class. Submitted to The American Journal of Physics. * Work supported by Department of Energy contract DE-AC03-76SFOO515. I. THE STANFORD LINEAR COLLIDER The newest experiments at Stanford Linear Accelerator Center (SLAC) use the SLAC Linear Collider, the SLC. Electrons and positrons, accelerated in the two-mile-long 50 GeV linear accelerator, crash head on in a prolific burst of subnuclear particles. To help capture and study the results of these collisions, physicists at SLAC and 32 other institutions have constructed a state of the art particle detector, the SLC Large Detector, or SLD. One of the most sophisticated machines in the world using the newest technology in detectors, SLD began receiving the first beams in mid-1991. In order to achieve the highest possible luminosity, the electron beams must be focused down to a very tiny spot at the interaction point. But the large magnetic fields (0.6 T) employed in this detector, along with the need to put instrumentation as close to the interaction point as possible, precludes the use of iron in the final focusing magnets.1 Thus the decision was made to use superconductors in the final focusing magnets, the so-called Superconducting Final Focus. Superconductors avoid the use of iron, which would distort the detector’s own magnetic field. Additionally, superconductors provide the ability to use extremely high currents to produce larger magnetic fields than can be obtained conventionally. Larger magnetic fields produce stronger focusing, so that the beam can be reduced to a much smaller spot, enhancing the probability of collisions. The

Focusing Electron Beams at SLAC.
I have always heard that a beam of electrons could be focused with magnets. While that seemed to make good sense, I had no clear idea of exactly how that could be done until I began spending my summers at SLAC, the Stanford Linear Accelerator Center. SLAC is operated for the U.S. Department of Energy by Stanford University, and it is located at the base of the foothills south of San Francisco, California.
