Title: Radiation shielding of the beam absorber in the MI 8-GeV beam line

Abstract

Results of Monte Carlo radiation shielding calculations performed for the beam absorber of the MI 8 GeV beam line are presented and discussed. The possibility to reach the level of 10{sup 19} protons per year is investigated.

  • Star density, hadron flux, and residual dose distributions are calculated around the {mu}2e diagnostic beam absorber. Corresponding surface and ground water activation, and air activation are presented as well.
  • The beam optics of the 12-GeV/c proton beam transfer line between the Low Energy Booster (LEB) and the Medium Energy Booster (MEB) at the Superconducting Super Collider is presented. The beam is extracted from the LEB vertically and is injected into the MEB through a vertical Lambertson magnet and a horizontal kicker. The beamline has high flexibility for amplitude and dispersion function matching. Effects of various errors in the transfer line are studied, and a beam position correction scheme is proposed. The beam optics of the 12-GeV/c absorber line transporting the beam from the LEB to an absorber during themore » LEB commissioning is also presented.« less

  • The present Heavy Ion Driver design for HYLIFE-II requires 96 beams from each side, or a total of 192 beams. The beams are separated from each other, at present, by an angle of 4.25 degrees. Two sets of Flibe (molten Salt) jets, 90 degrees apart, are used for x-ray and neutron shielding of the first vessel wall. Space between jets result in no shielding of each beam tube and a surrounding rectangular area of vessel wall. A vortex shielding device is proposed to provide this additional required shielding. This report describes the near ideal quality of Flibe jets that aremore » needed, for the shielding design to be practical. First wall shielding at locations other than close proximity to the beam lines, is accomplished by oscillating flow and extensions to the horizontal beam protection jets.« less
