Book Description
This note constitutes a Letter of Interest to study the physics capabilities of, and to develop an implementation plan for, a neutrino physics program based on a Low-Energy Neutrino Factory at Fermilab providing a? beam to a detector at the Deep Underground Science and Engineering Laboratory. It has been over ten years since the discovery of neutrino oscillations [1] established the existence of neutrino masses and leptonic mixing. Neutrino oscillations thus provide the first evidence of particle physics beyond the Standard Model. Most of the present neutrino oscillation data are well described by the 3? mixing model. While a number of the parameters in this model have already been measured, there are several key parameters that are still unknown, namely, the absolute neutrino mass scale, the precise value of the mixing angles, the CP phase? and hence the presence or absence of observable CP-violation in the neutrino sector. Future measurements of these parameters are crucial to advance our understanding of the origin of neutrino masses and of the nature of flavor in the lepton sector. The ultimate goal of a program to study neutrino oscillations goes beyond a first measurement of parameters, and includes a systematic search for clues about the underlying physics responsible for the tiny neutrino masses, and, hopefully, the origin of the observed flavor structure in the Standard Model, as well as the possible source of the observed matter-antimatter asymmetry in the Universe. To achieve this goal will almost certainly require precision measurements that go well beyond the presently foreseen program. One of the most promising experimental approaches to achieve some of the goals mentioned above is to build a Neutrino Factory and its corresponding detector. The Neutrino Factory produces neutrino beams from muons which have been accelerated to an energy of, for example, 25 GeV. The muons are stored in a race-track shaped decay ring and then decay along the straight sections of the ring. Since the decay of the muon is well understood, the systematic uncertainties associated with a neutrino beam produced in this manner are very small. Beam diagnostics in the decay ring and a specially designed near detector further reduce the systematic uncertainties of the neutrino beam produced at the Neutrino Factory. In addition since the muon (anti-muon) decays produce both muon and anti-electron neutrinos (anti-muon and electron neutrinos), many oscillation channels are accessible from a Neutrino Factory, further extending the reach in the oscillation parameter space. Over the last decade there have been a number of studies [2-5] that have explored the discovery reach of Neutrino Factories in the small mixing angle,?13, and its capability to determine the mass hierarchy and determine if CP is violated in leptons through observation of phase parameter,?. The most recent study to be completed [6], the International scoping study of a future Neutrino Factory and super-beam facility (the ISS), studied the physics capabilities of various future neutrino facilities: super-beam,?-Beam and Neutrino Factory and has determined that the Neutrino Factory with an energy of H"5 GeV has the best discovery reach for small values of sin22?13, reaching an ultimate sensitivity of between 10−5 and 10−4. However, for larger values of sin22?13 (> 10−3), the sensitivity of other experimental approaches is competitive to that of the 25 GeV Neutrino Factory. The wide-band neutrino beam (WBB) produced at Fermilab and directed towards DUSEL [7] is one such competitor. For the case where sin22?13 (> 10−3) is large, initial studies have shown that a Low-Energy Neutrino Factory [8-10] with an energy of, for example, 4 GeV, may be both cost-effective and offers exquisite sensitivity. The required baseline for a Low-Energy Neutrino Factory matches Fermilab to DUSEL and, therefore, its physics potential and implementation should be studied in the context of DUSEL along with those for the WBB.

Book Description
The Neutrino Factory, which produces an extremely intense source of flavor-tagged neutrinos from muon decays in a storage ring, arguably gives the best physics reach for CP violation, as well as virtually all parameters in the neutrino oscillation parameter space. I will briefly describe the physics capabilities of the baseline Neutrino Factory as compared to other possible future facilities ([beta]-beam and super-beam facilities), give an overview of the accelerator complex and describe in detail the current international R & D program.

Book Description
The beta-beam concept for the generation of electron neutrino beams was first proposed by Piero Zucchelli in 2002. The idea created quite a stir, challenging the idea that intense neutrino beams only could be produced from the decay of pions or muons in classical neutrino beams facilities or in future neutrino factories. The concept initially struggled to make an impact but the hard work by many machine physicists, phenomenologists and theoreticians over the last five years has won the beta-beam a well-earned position as one of the frontrunners for a possible future world laboratory for high intensity neutrino oscillation physics. This is the first complete monograph on the beta-beam concept. The book describes both technical aspects and experimental aspects of the beta-beam, providing i) students and scientists with an insight into the possibilities offered by beta-beams; ii) facility designers with a starting point for future studies; and iii) policy makers with a comprehensive picture of the limits and possibilities offered by a beta-beam./a

Book Description
The physics of neutrinos--uncharged elementary particles that are key to helping us better understand the nature of our universe--is one of the most exciting frontiers of modern science. This book provides a comprehensive overview of neutrino physics today and explores promising new avenues of inquiry that could lead to future breakthroughs. The Physics of Neutrinos begins with a concise history of the field and a tutorial on the fundamental properties of neutrinos, and goes on to discuss how the three neutrino types interchange identities as they propagate from their sources to detectors. The book shows how studies of neutrinos produced by such phenomena as cosmic rays in the atmosphere and nuclear reactions in the solar interior provide striking evidence that neutrinos have mass, and it traces our astounding progress in deciphering the baffling experimental findings involving neutrinos. The discovery of neutrino mass offers the first indication of a new kind of physics that goes beyond the Standard Model of elementary particles, and this book considers the unanticipated patterns in the masses and mixings of neutrinos in the framework of proposed new theoretical models. The Physics of Neutrinos maps out the ambitious future facilities and experiments that will advance our knowledge of neutrinos, and explains why the way forward in solving the outstanding questions in neutrino science will require the collective efforts of particle physics, nuclear physics, astrophysics, and cosmology.

Book Description
The workshop has reviewed progress towards the future generation of neutrino oscillation experiments. These experiments will use very intense conventional neutrino beams and novel beams derived from muons or radioactive nuclei. These new facilities will provide a broad research front including muon physics and neutrino scattering experiments. The main technical challenges involve construction of very intense proton beams, targeting, effective capture of produced particles, cooling and ultra-fast acceleration of the resulting muons.
