| TUPMY006 | MICE Step IV Optics without the M1 Coil in SSD | 1553 |

Funding: Fermi National Accelerator Laboratory The international Muon Ionization Cooling Experiment (MICE) will demonstrate ionization cooling, the only technique that, given the short muon lifetime, can reduce the phase-space volume occupied by a muon beam quickly enough. MICE will demonstrate cooling in two steps. In the first one, Step IV, MICE will study the multiple Coulomb scattering in liquid hydrogen (LH2) and lithium hydride (LiH). A focus coil module will provide focussing on the absorber. The transverse emittance will be measured upstream and downstream of the absorber in two spectrometer solenoids (SS). Magnetic fields generated by two match coils in the SSs allow the beam to be matched into a flat-field regions in which the tracking detectors are installed. An incident in September 2015 rendered matching coil \#1 (M1D) of the downstream spectrometer inoperable. A new Step IV lattice without M1D and its optimization via a Genetic Algorithm (GA) will be described in this paper. |

| THPMB053 | nuSTORM FFAG Decay Ring | 3369 |
|
||
| The neutrino beam produced from muons decaying in a storage ring would be an ideal tool for precise neutrino cross section measurements and search for sterile neutrinos due to its precisely known flavour content and spectrum. In the proposed nuSTORM facility pions would be directly injected into a racetrack storage ring, where circulating muon beam would be captured. The storage ring has two options: a FODO solution with large aperture quadrupoles and a racetrack FFAG (Fixed Field Alternating Gradient) using the recent developments in FFAGs. Machine parameters, linear optics design and beam dynamics are discussed in this paper. | ||

| THPMB054 | FFAG Beam Line for nuPIL - Neutrinos from PIon Beam Line | 3372 |
|
||
| The Long Baseline Neutrino Facilities (LBNF) program aims to deliver a neutrino beam for the Deep Underground Neutrino Experiment (DUNE). The current baseline for LBNF is a conventional magnetic horn and decay pipe system. Neutrinos from PIon beam Line (nuPIL) is a part of the optimization effort to optimize the LBNF. It consists of a pion beam line after the horn to clean the beam of high energy protons and wrong-sign pions before transporting them into a decay beam line, where instrumentation could be implemented. This paper focuses on the FFAG solution for this pion beam line. The resulting neutrino flux is also presented. | ||

| THPMB055 | A FODO Beam Line Design for nuPIL | 3375 |
|
||
|
Funding: Fermi National Accelerator Laboratory The Fermilab Deep Underground Neutrino Experiment (DUNE) was proposed to determine the neutrino mass hierarchy and demonstrate leptonic CP violation. The current design of the facility that produces the neutrino beam (LBNF) uses magnetic horns to collect pions and a decay pipe to allow them to decay. In this paper, a design of a possible alternative for the conventional neutrino beam in LBNF is presented. In this design, a FODO magnet beam line is used to collect the pions from the downstream face of a horn, bend them by ∼ 5.8 degrees and then transport them in a straight beam line where they decay to produce neutrinos. The idea of using neutrinos from the PIon beam Line (nuPIL) provides flavor-pure neutrino beams that can be well understood by implementing standard beam measurement technology. The neutrino flux and the resulting δCP sensitivity from the FODO nuPIL are also presented in the paper. |
