“…The simulation code pyORBIT [6] with PTC external libraries has been used to characterize the lattice and optics with beam. Direct and indirect space charge forces, based on an FFT model, are included in the code, which are needed to realistically evaluate the effect of the space charge in the accumulator.…”

“…Although the simulation approach with simple 2D tracking is quite adequate in showing the underlying nonlinear dynamics, it is necessary to benchmark those simulations with a more detailed 6D tracking. This has been done using the universal pyOrbit code developed jointly by Oak Ridge National Laboratory and CERN [15]. There are several important differences in performance introduced by the extension of the tracking to all six dimensions.…”

The slow resonant extraction of a beam in a storage ring is a very well-established technique. Several high-energy physics accelerator facilities around the world are currently using this technique for highintensity beam operations. As the demand for beam power is constantly growing, extraction efficiency in many cases is becoming a limiting factor. In this report, we discuss a new effective approach to improving the slow extraction efficiency by using configurations of higher multipoles. We will describe this approach, determine optimal multipole configurations, and present the results of simulations to support the proposed recipe. We found that, with the use of higher multipole field content, the extraction efficiency can be improved, and, therefore, the level of prompt and residual radioactivity in the accelerator components and surrounding buildings can be reduced by as much as 40% or more. We also explored manipulating the higher-order effects produced in the pure sextupole configurations for the same purpose and demonstrated that similar results can be achieved by only rearranging the sextupole magnets in the lattice.

“…In general, the results of the Fig. 6 have been simulated with the help of PYORBIT code [8,9] that involves quantum mechanical interaction of laser beam and bunch of H 0 particles. The code calculates interaction of individual particle excitation/stripping efficiency and averages over the whole bunch.…”

A new scheme with sequential resonant excitation for laser assisted charge exchange injection of H − beams is proposed. In contrast with the one step excitation scheme, the proposed scheme requires significantly less laser power for high efficiency stripping. It also provides greater flexibility in the choice of laser wavelength for a given beam energy and extends the range of energies where laser stripping can be effectively applied. Calculations and experimental plans for 1.0 GeV and 1.3 GeV H − beams at the Spallation Neutron Source are presented. Results indicate that the sequential excitation scheme allows the use of more convenient green laser with much smaller power in place of the UV laser previously used.
