Book excerpt: The muon collection scheme for a muon-storage-ring-based Neutrino Factory consists of a target irradiated with a 1 MW proton beam followed by a 30-m decay channel and then a 300-m long induction linac phase rotation. The purpose of the induction-linac section is to reduce the [delta]E/E spread of the collected muons to a value which is manageable for the subsequent buncher and cooling sections. We describe in this paper the overall design concept of the phase-rotation system and give key parameters for the induction linacs.

Download or read book MUON POLARIZATION EFFECTS IN THE FRONT END OF THE NEUTRINO FACTORY. written by and published by . This book was released on 2000 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors summarize the methods used for simulation of polarization effects in the front end of a possible neutrino factory. They first discuss the helicity of muons in the pion decay process. They find that, neglecting acceptance considerations, the average helicity asymptotically approaches a magnitude of 0.185 at large pion momenta. Next they describe the methods used for tracking the spin through the complicated electromagnetic field configurations in the front end of the neutrino factory, including rf phase rotation and ionization cooling channels. Various depolarizing effects in matter are then considered, including multiple Coulomb scattering and elastic scattering from atomic electrons. Finally, they include all these effects in a simulation of a 480 m long, double phase rotation front end scenario.

Download or read book MUON POLARIZATION IN A FRONT-END CHANNEL OF A NEUTRINO FACTORY. written by and published by . This book was released on 2001 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: As one of the figures of merit, muon polarization and its correlation to the particle arrival time was studied for the high intensity muon beam source of a Neutrino Factory. Muon polarization, 100% polarized in the parent pion rest system, was tracked down the pion capture, phase rotation, and ionization cooling channels, using the BMT equation. A study was done of the dependence of the muon polarization and its correlation on the configuration of induction linac channels in the phase rotation channel. Depolarization effects of the muon polarization through absorbers in the ionization cooling channel was simulated.

This workshop brought together experts from a variety of disciplines to explore new and profound ways proton accelerators can be used in the future. The workshop explored uses of such a proton source for producing intense muon, kaon and neutrino beams as well as using the intense protons for new forms of nuclear reactors that go by the name Accelerator Driven Sub-critical systems that promise to increase our available nuclear fuel supply by orders of magnitude while at the same time solving the nuclear waste problem. Intense proton beams can also be used to produce short-lived nuclear isotopes that are important in the medical industry.
Book Synopsis Induction Accelerators by : Ken Takayama
Download or read book Induction Accelerators written by Ken Takayama and published by Springer Science & Business Media. This book was released on 2010-10-05 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: A broad class of accelerators rests on the induction principle whereby the accelerating electrical fields are generated by time-varying magnetic fluxes. Particularly suitable for the transport of bright and high-intensity beams of electrons, protons or heavy ions in any geometry (linear or circular) the research and development of induction accelerators is a thriving subfield of accelerator physics. This text is the first comprehensive account of both the fundamentals and the state of the art about the modern conceptual design and implementation of such devices. Accordingly, the first part of the book is devoted to the essential features of and key technologies used for induction accelerators at a level suitable for postgraduate students and newcomers to the field. Subsequent chapters deal with more specialized and advanced topics.

Book Synopsis New Initiatives On Lepton Flavor Violation And Neutrino Oscillation With High Intense Muon And Neutrino Sources by : Yoshitaka Kuno
Download or read book New Initiatives On Lepton Flavor Violation And Neutrino Oscillation With High Intense Muon And Neutrino Sources written by Yoshitaka Kuno and published by World Scientific. This book was released on 2002-10-07 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area of physics involving muons and neutrinos has become exciting in particle physics. Using their high intensity sources, physicists undertake, in various ways, extensive searches for new physics beyond the Standard Model, such as tests of supersymmetric grand unification (SUSY-GUT) and precision measurements of the muon and neutrino properties, which will in future extend to ambitious studies such as determination of the three-generation neutrino mixing matrix elements and CP violation in the lepton sector. The physics of this field is advancing, with potential improvements of the sources. Many R&D projects, such as those concerning high intensity, low energy muon sources or a neutrino factory, are being carried out or planned at various places. Some of those topics are included in this book.
Book Synopsis Interim Design Report for the International Design Study for a Neutrino Factory by :
Download or read book Interim Design Report for the International Design Study for a Neutrino Factory written by and published by . This book was released on 2011 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The starting point for the International Design Study for the Neutrino Factory (the IDS-NF) was the output of the earlier International Scoping Study for a future Neutrino Factory and super-beam facility (the ISS). The accelerator facility described in section 2 incorporates the improvements that have been derived from the substantial amount of work carried out within the Accelerator Working Group. Highlights of these improvements include: (1) Initial concepts for the implementation of the proton driver at each of the three example sites, CERN, FNAL, and RAL; (2) Detailed studies of the energy deposition in the target area; (3) A reduction in the length of the muon beam phase-rotation and bunching systems; (4) Detailed analyses of the impact of the risk that stray magnetic field in the accelerating cavities in the ionization cooling channel will reduce the maximum operating gradient. Several alternative ionization-cooling lattices have been developed as fallback options to mitigate this technical risk; (5) Studies of particle loss in the muon front-end and the development of strategies to mitigate the deleterious effects of such losses; (6) The development of more complete designs for the muon linac and re-circulating linacs; (7) The development of a design for the muon FFAG that incorporates insertions for injection and extraction; and (8) Detailed studies of diagnostics in the decay ring. Other sub-systems have undergone a more 'incremental' evolution; an indication that the design of the Neutrino Factory has achieved a degree of maturity. The design of the neutrino detectors described in section 3 has been optimized and the Detector Working Group has made substantial improvements to the simulation and analysis of the Magnetized Iron Neutrino Detector (MIND) resulting in an improvement in the overall neutrino-detection efficiency and a reduction in the neutrino-energy threshold. In addition, initial consideration of the engineering of the MIND has generated a design that is feasible and a finite element analysis of the toroidal magnetic field to produce a realistic field map has been carried out. Section 3 also contains, for the first time, a specification for the near-detector systems and a demonstration that the neutrino flux can be determined with a precision of 1% through measurements of inverse muon decay at the near detector. The performance of the facility, the work of the Physics and Performance Evaluation Group, is described in section 1. The effect of the improved MIND performance is to deliver a discovery reach for CP-invariance violation in the lepton sector, the determination of the mass hierarchy, and of?13 that extends down to values of sin2 2?13 H"5 x 10−5 and is robust against systematic uncertainties. In addition, the improved neutrino-energy threshold has allowed an indicative analysis of the kind of re-optimization of the facility that could be carried out should?13 be found close to the current upper bound. The results presented in section 1 demonstrate that the discovery reach as well as the precision with which the oscillation parameters can be measured at the baseline Neutrino Factory is superior to that of other proposed facilities for all possible values of sin2 2?13.

Download or read book Studies of the Front End of a Neutrino Factory written by and published by . This book was released on 2001 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: A neutrino factory employs muons which are produced, collected, cooled, accelerated and then stored so that their eventual decay produces an intense neutrino beam. A general description may be found in the paper by Geer [S. Geer, Phys. Rev. D, 57, 1 (1998)], and two upcoming Comments on Nuclear and Particle Physics articles [S. Geer, ''Future prospects for muon facilities'', see http://www-mucool.fnal.gov/mcnotes/muc0154.ps; also A. M. Sessler, ''Neutrino Factories: The Facility'', http://www-mucool.fnal.gov/mcnotes/muc0155.pdf]. In this contribution, we use analytic and numerical tools to investigate the performance of the front end of a neutrino factory. This region starts just after the target and ends just prior to the recirculating accelerators. Extensive previous work has resulted in designs used in the Fermilab Study of 1999-2000 and the Brookhaven Study of 2000-2001. Here we explore variations away from these particular designs, seeking possible improvements in final muon output, risk reduction, and ultimate cost. Our studies include changes in the overall front end geometry through optimization of the induction linac design and variations of the rf frequency in the cooling channel acceleration, and initial exploration of the use of helical wiggler fields to increase the range of initial muon energies that are captured.

Book Synopsis Evolutionary Algorithm for the Neutrino Factory Front End Design by :
Download or read book Evolutionary Algorithm for the Neutrino Factory Front End Design written by and published by . This book was released on 2009 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Neutrino Factory is an important tool in the long-term neutrino physics program. Substantial effort is put internationally into designing this facility in order to achieve desired performance within the allotted budget. This accelerator is a secondary beam machine: neutrinos are produced by means of the decay of muons. Muons, in turn, are produced by the decay of pions, produced by hitting the target by a beam of accelerated protons suitable for acceleration. Due to the physics of this process, extra conditioning of the pion beam coming from the target is needed in order to effectively perform subsequent acceleration. The subsystem of the Neutrino Factory that performs this conditioning is called Front End, its main performance characteristic is the number of the produced muons.
