A new type of charge-exchange injection scheme for high-intensity proton rings that use a laser beam and an undulator magnet is proposed. The elementary stripping process is resonant photoionization via a broad Stark state formed by the Stark effect at an energy level near the peak of the potential barrier. The method used to estimate the parameters of the necessary laser beam and magnetic field is described. As an application to an actual accelerator, a laser stripping system using a high-finesse Fabry-Perot resonator and an undulator is proposed. An estimation of the photon loss due to the pumping-up of H$^0$ atoms, tunability of the system and the emittance growth due to stripping in the undulator magnet is also given.
A single gap, 352 MHz superconducting reentrant cavity for 5-100 MeV beams has been designed and it is presently under construction. This development is being done in the framework of a 30 mA proton linac project for nuclear waste transmutation. Mech
This lecture is an introduction to the design of a spallation neutron source and other high intensity proton sources. It discusses two different approaches: linac-based and synchrotron-based. The requirements and design concepts of each approach are
Project-X is the proposed high intensity proton facility to be built at Fermilab, US. Its Superconducting Linac, to be used at first stage of acceleration, will be operated in continuous wave (CW) mode. The Linac is divided into three sections on the
A new, hybrid design is proposed to eliminate the main systematic errors in the frozen spin, storage ring measurement of the proton electric dipole moment. In this design, electric bending plates steer the particles, and magnetic focusing replaces el
A new experiment is described to detect a permanent electric dipole moment of the proton with a sensitivity of $10^{-29}ecdot$cm by using polarized magic momentum $0.7$~GeV/c protons in an all-electric storage ring. Systematic errors relevant to the
