Title: ORBIT INJECTION DUMP SIMULATIONS OF THE H0 AND H- BEAMS

Abstract

Simulations of the transport of H0 and H- beams to the Spallation Neutron Source (SNS) ring injection dump are carried out using the ORBIT code. During commissioning and early operations, beam losses in this region have been the highest in the accelerator and have presented the most obvious hurdle to cross in achieving high intensity operation. Two tracking models are employed: 1) a piecewise continuous symplectic representation of the lattice elements in the injection chicane and dump line, and 2) particle tracking in full 3D magnetic fields, as obtained from OPERA code evaluations. The physics models also include estimations of scattering from both the primary and secondary stripper foils, and beam losses due to apertures throughout the beam line.

  • The two-step charge-changing injection used in the Los Alamos Proton Storage Ring (PSR) requires stripping of H/sup -/ to H/sup 0/ by high magnetic fields and subsequent stripping of H/sup 0/ to H/sup +/ by a carbon foil. The authors consider single- and multiphoton laser ionization as alternatives to using a fragile foil. The multiphoton case is of possible interest for selection of practical lasers, which tend to have increased power output at higher wavelengths. The formulas derived express the necessary laser powers for ionization of monoenergetic H/sup 0/ beams; they also hold for beams of particles other than atomicmore » hydrogen. The numerical examples given are for the 800-MeV PSR beam with momentum spread taken into account. Additionally, they discuss selective stripping as an implication of the inherent energy selectivity of the photoionization process.« less

  • This article presents a report on the progress made in designing 18 MW water based Beam Dumps for electrons or positrons for an International Linear Collider (ILC). Multi-dimensional technology issues have to be addressed for the successful design of the Beam Dump. They include calculations of power deposition by the high energy electron/positron beam bunch trains, computational fluid dynamic analysis of turbulent water flow, mechanical design, process flow analysis, hydrogen/oxygen recombiners, handling of radioactive 7Be and 3H, design of auxiliary equipment, provisions for accident scenarios, remote window exchanger, radiation shielding, etc. The progress made to date is summarized, the currentmore » status, and also the issues still to be addressed.« less
  • 3D computer simulations are performed to study magnetic field distributions and particle trajectories along the SNS ring injection momentum dump line. Optical properties and transfer maps along the dump line are calculated. The stripped proton particle distributions on the dump window are analyzed. The study has provided useful information for the redesign of the SNS ring injection beam dump.
  • The JET neutral injection beam line consists of a large neutral injection box (approx. 7m x 3.6m x 3m) with eight 'PINI's' (Plug-In Neutral Injector) attached to its back panel. The PINI's are mounted in two vertical banks of four. The charged particles are separated from the neutrals during the passage through a deflection magnet and are subsequently intercepted by full energy ion dumps and fractional energy ion dumps. The neutralized beam can be intercepted by a calorimeter which can be rotated out of the beam to allow injection into the plasma. The design of the calorimeter and full energymore » ion dump are the subject matter of this paper.« less
