MOPZ008 | Particle Production Simulations for the Neutrino Factory Target | 835 |
|
||
Funding: EU FP7 EUROnu WP3 In the International Design Study for the Neutrino Factory (IDS-NF), a proton beam with a kinetic energy between 5 and 15 GeV interacts with a liquid mercury jet target in order to produce pions that will decay to muons, which in turn decay to neutrinos. The target is situated in a solenoidal field tapering from 20 T down to 1.5 T over a length of several metres, allowing for an optimised capture of pions in order to produce a useful muon beam for the machine. We present results of target particle production calculations using MARS, FLUKA and G4BEAMLINE simulation codes. |

MOPZ030 | Status of Studies of Achromat-based 6D Ionization Cooling Rings for Muons | 865 |

Funding: This work was supported by the U.S. Department of Energy in part under award numbers DE-FG02-92ER40695 (UCLA), DE-AC02-98CH10886 (BNL) and DE-FG02-07ER84855 (Particle Beam Lasers, Inc.)” Six dimensional ionization cooling of muons is needed to achieve the necessary luminosity for a muon collider. If that cooling could occur over multiple turns in a closed ring, there would be significant cost savings over a single-pass cooling channel. We report on the status of a cooling ring with achromatic arcs. The achromatic design permits the design to easily switch between a closed ring and a snaking geometry on injection or extraction from the ring. The ring is designed with sufficient space in each superperiod for injection and extraction magnets. We describe the ring's lattice design, performance, and injection/extraction requirements. |

TUPS053 | A Target Magnet System for a Muon Collider and Neutrino Factory | 1650 |
|

Funding: This work is supported in part by the US DOE Contract NO. DE-AC02-98CH10886. The target system envisioned for a Muon Collider or Neutrino Factory includes a 20-T solenoid field surrounding a mercury jet target with the field tapering to 1.5 T 15 m downstream of the target. A principal challenge is to shield the superconducting magnets from the radiation issuing from the 4-MW proton beam impacting the target. We describe a solution which will deliver the desired field while being capable of tolerating the intense radiation environment surrounding the target. |

Funding: This work is supported in part by the US DOE Contract NO. DE-AC02-98CH10886. We present the results of power deposition in various components of the baseline target station of a Muon Collider or a Neutrino Factory driven by a 4-MW proton beam. |

WEPS016 | Update on Comparison of the Particle Production using MARS Simulation Code | 2514 |
|
||
Funding: EU FP7 EUROnu WP3 In the International Design Study for the Neutrino Factory (IDS-NF), a 5-15 GeV (kinetic energy) proton beam impinges a Hg jet target in order to produce pions that will decay into muons. The muons are then captured and transformed into a beam that can be passed to the downstream acceleration system. The target sits in a solenoid field tapering from 20 T down to below 2 T over several meters permitting a optimized capture of the pions that will produce useful muons for the machine. The target and pion capture system have been simulated in MARS simulation code and this work presents an updated comparison of the particles production using the MARS code versions m1507 and m1510. |
