We describe the physics potential of ee linear colliders in this report. These machines are planned to operate in the first phase at a center–of–mass energy of 500 GeV, before being scaled up to about 1 TeV. In the second phase of the operation, a final energy of about 2 TeV is expected. The machines will allow us to perform precision tests of the heavy(More)
The cross section for y + d -+ P" + d has at 6, 12, and 18 GeV for t between -.15(GeV/c) pen measured and -1.4(GeV/c)2. From these measurements the total and differential p"-nucleon cross sectionshave been determined together with 7,2/4x.

We have measured no photoproduction between t = -0.1 and -0.4 (GeV/c)2 at incident photon energies of 4, 6, 9, 12, and 18 GeV, using a high-pressure, low-temperature gaseous hydrogen target and a collimated bremsstrahlung beam from the 20 GeV Stanford Linear Accelerator. The process was identified by observing the recoil proton in the SLAC 1.6 GeV/c(More)
The asymmetry in the process y + p +x0 +p with polarized photons has been measured at 6 GeV for momentum transfers from t = -0.4(GeV/c)2 to t = -1.1(GeV/c)2. The experiment was performed at the Stanford Linear Accelerator Center using coherent bremsstrahlung from a diamond crystal. A coincidence was made between the recoil proton in the S.L.A.C. 1.6 GeV/c(More)
Measurements have been made on Compton scattering at the Stanford Linear Accelerator Center for photon energies between 5 and 17 GeV and.t-values from -0.06 tc -1.1 (GeV/c)2. The data were obtained by performing a coincidence between the SLAC 1.6 GeV/c spectrometer and a lucite shower counter. The scattering appears diffractive out to high t-values, but the(More)
The development of particle accelerators is traced from the simple but ingenious table-top devices conceived during the late 1920s to the present day's large, complex machines which extend over tens of kilometers. The emphasis is on Rolf Wideröe and his seminal contributions to the field. Not only did Wideröe construct the first accelerator which(More)
A thermal diffusion column allows a recovery of 99+/-1 percent of the tritium originally contained in about 50 liters at standard temperature and pressure of hydrogen gas in a final volume of 3.8 liters over a 2-day period. After a tenfold enrichment by electrolysis, a tritium concentration of 10(-18) with an experimental error of a few percent may be(More)
