Abstract

We present FLUKA and MARS simulation studies of the pion production and energy deposition in the Neutrino Factory baseline target station, which consists of a 4 MW proton beam interacting with a liquid mercury jet target within a 20 T solenoidal magnetic field. We show that a substantial increase in the shielding is needed to protect the superconducting coils from too much energy deposition. Investigations reveal that it is possible to reduce the magnetic field in the solenoid capture system without adversely affecting the pion production efficiency. We show estimates of the amount of concrete shielding that will be required to protect the environment from the high radiation doses generated by the target station facility. We also present yield and energy deposition results for alternative targets: gallium liquid jet, tungsten powder jet and solid tungsten bars.

Highlights

  • The current baseline option for the Neutrino Factory [1] is to use a 4 MW proton beam interacting with a freeflowing mercury jet to create an intense muon beam [2]

  • We present a series of simulation studies, using the FLUKA [4] and MARS [5] computer packages, on particle production and energy deposition calculations

  • We present a study on the concrete shielding requirements that will be necessary to protect the environment from the high radiation doses emanating from the target station

Summary

INTRODUCTION

The current baseline option for the Neutrino Factory [1] is to use a 4 MW proton beam interacting with a freeflowing mercury jet to create an intense muon beam [2]. The interaction of the bunched proton beam (rms bunch length equal to 3 ns) with the mercury jet creates low-energy pions that are captured by the high field ($ 20 T) solenoid and transported through a decay channel. We present a series of simulation studies, using the FLUKA [4] and MARS [5] computer packages, on particle production and energy deposition (radiation dose) calculations. We present a study on the concrete shielding requirements that will be necessary to protect the environment from the high radiation doses emanating from the target station
