In proton radiography, imaging with systems consisting of quadrupole magnets is an established technique for viewing the material distribution and composition of objects, either statically or during fast events such as explosions. With the standard m

Multi-turn injection of H/sup -/ by foil stripping into an accumulator ring produces metastable neutrals that contribute to machine activation. Placing the foil in a magnetic field has been shown to greatly reduce such losses. However, the electrons

A proton microscope has been developed for radiography applications using the 800-MeV linear accelerator at the Los Alamos Neutron Science Center (LANSCE). The microscope provides a magnified image of a static device, or of a dynamic event such as a

The HEBT of the proposed Advanced Hydrotest Facility (AHF) is designed to deliver 50-GeV protons to an object from 12 directions, 15/spl deg/ apart. Individual beam bunches extracted from a synchrotron are split with 11 sets of septa such that, nomin

The 1-MW spallation-neutron source under design study at Los Alamos is driven by a linac-compressor-ring scheme that utilizes a large portion of the existing Los Alamos Meson Physics Facility (LAMPF) linac, as well as the facility infrastructure. The

A new compressor ring for 790-MeV protons is proposed at Los Alamos National Laboratory to provide 1 MW of beam power for a spallation-neutron source. The design has unit-transfer-matrix achromatic arcs. Bunching, beam-control, and extraction element

A design study for an accelerator-driven spallation-neutron source is underway at Los Alamos. The driver, based on the LAMPF facility, produces a 1-MW proton beam and is upgradable to 5 MW. After linear acceleration to full energy, an H/sup -/ beam i

We describe the new injection line to be implemented for the Los Alamos Proton Storage Ring (PSR) in the change from a two-step injection process to direct H/sup -/ injection. While obeying all geometrical constraints imposed by the existing structur
