We present a plan for a 45-GeV 40-..mu..A proton synchrotron with a 200-..mu..A 9-GeV booster. These machines can provide simultaneously 45-GeV slow-extracted beam for production of kaons, antiprotons, and other secondary particles, and 9-GeV fast-extracted beam for neutrino and pulsed muon physics. The LAMPF II machines are compared with existing and proposed kaon factories. Relative to the Brookhaven AGS as it exists today, LAMPF II will provide 90 times as many neutrino events per year and 300 times as many kaons per year. A number of experiments requiring vastly increased beam current are examined. Two programs, the search for quark-gluon plasma using high-energy antiproton annihilation in nuclei, and the measurement of nuclear quark structure functions using the Drell-Yan process, address the highest priority problems of the NSAC long-range plan. Some of the design features of the LAMPF II accelerators are shown to be important for reducing beam losses and increasing beam availability. Because of the large rf power and voltage required, innovation on ferrite-tuned cavities is required. A commercially available Mg-Mn ferrite with perpendicular bias has been shown to raise the available ferrite Q by more than a factor of 10 compared with the materials now in use at other accelerators. A preliminary cost estimate is discussed. The cost of the LAMPF II machine is compared with estimates of several other proposed machines made with the same set of costing algorithms. The 45-GeV LAMPF II proposal produces far more neutrinos, kaons, and antiprotons per unit cost than an upgraded conventional machine. The LAMPF II booster alone, which can provide 100 ..mu..A at 12 GeV, is shown to be a very interesting option at moderate cost.
