This book was released on 2000-11-17 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings report the ever increasing interest and scientific case for the muon collider and the neutrino factory. There were intense sessions on the current design of neutrino factories in Europe, Japan, and in the USA, and there is growing evidence for a low-mass Higgs boson from the precision electroweak parameters to motivate the development of a Higgs factory. The twin themes of a neutrino factory and a Higgs factory have provided a possible plan for a future program in the USA. Some of the highlights of this conference were: The very latest news on the Higgs search at LEP II, the strong case for a low-mass Higgs, the push to find SUSY particles, the neutrino mass, the interesting possibility that the SuperKamiokande results could somehow be the result of neutrino decay, the beautiful arguments for a scalar collider, the summary of the future of CERN, and particle physics in general, and the overview of the Standard Model.

Book excerpt: The concept of a Muon Collider was first proposed by Budker [10] and by Skrinsky [11] in the 60s and early 70s. However, there was little substance to the concept until the idea of ionization cooling was developed by Skrinsky and Parkhomchuk [12]. The ionization cooling approach was expanded by Neufer [13] and then by Palmer [14], whose work led to the formation of the Neutrino Factory and Muon Collider Collaboration (MC) [3] in 1995. The concept of a neutrino source based on a pion storage ring was originally considered by Koshkarev [18]. However, the intensity of the muons created within the ring from pion decay was too low to provide a useful neutrino source. The Muon Collider concept provided a way to produce a very intense muon source. The physics potential of neutrino beams produced by muon storage rings was investigated by Geer in 1997 at a Fermilab workshop [19, 20] where it became evident that the neutrino beams produced by muon storage rings needed for the muon collider were exciting on their own merit. The neutrino factory concept quickly captured the imagination of the particle physics community, driven in large part by the exciting atmospheric neutrino deficit results from the SuperKamiokande experiment. As a result, the MC realized that a Neutrino Factory could be an important first step toward a Muon Collider and the physics that could be addressed by a Neutrino Factory was interesting in its own right. With this in mind, the MC has shifted its primary emphasis toward the issues relevant to a Neutrino Factory. There is also considerable international activity on Neutrino Factories, with international conferences held at Lyon in 1999, Monterey in 2000 [21], Tsukuba in 2001 [22], and another planned for London in 2002.

Book excerpt: Muon Colliders provide a path to the energy frontier in particle physics but have been regarded to be "at least 20 years away" for 20 years. I will review recent progress in design studies and hardware R & D and show that a Muon Collider can be established as a real option for the post-LHC era if the current vigorous R & D effort revitalized by the Muon Collider Task Force at Fermilab can be supported to its conclusion. All critical technologies are being addressed and no show-stoppers have emerged. Detector backgrounds have been studied in detail and appear to be manageable and the physics can be done with existing detector technology. A muon facility can be built through a staged scenario starting from a low-energy muon source with unprecedented intensity for exquisite reach for rare processes, followed by a Neutrino Factory with ultrapure neutrino beams with unparalleled sensitivity for disentangling neutrino mixing, leading to an energy frontier Muon Collider with excellent energy resolution.

Book excerpt: During the 1990s an international collaboration has been studying the possibility of constructing and operating a high-energy high-luminosity[mu][sup+][mu][sup[minus]] collider. Such a machine could be the approach of choice to extend the discovery reach beyond that of the LHC. More recently, a growing collaboration is exploring the potential of a stored-muon-beam neutrino factory to elucidate neutrino oscillations. A neutrino factory could be an attractive stepping-stone to a muon collider. Its construction, possibly feasible within the coming decade, could have substantial impact on neutrino physics.

Book excerpt: There is considerable interest in the use of muon beams to create either an intense source of decay neutrinos aimed at a detector located 3000-7500 km away (a Neutrino Factory), or a Muon Collider that produces high-luminosity collisions at the energy frontier. R & D aimed at producing these facilities has been under way for more than 10 years. This paper will review experimental results from MuCool, MERIT, and MICE and indicate the extent to which they will provide proof-of-principle demonstrations of the key technologies required for a Neutrino Factory or Muon Collider. Progress in constructing components for the MICE experiment will also be described.

Book excerpt: A full high energy muon collider may take considerable time to realize. However, intermediate steps in its direction are possible and could help facilitate the process. Employing an intense muon source to carry out forefront low energy research, such as the search for muon-number non-conservation, represents one interesting possibility. For example, the MECO proposal at BNL aims for 2 x 10[sup[minus]17] sensitivity in their search for coherent muon-electron conversion in the field of a nucleus. To reach that goal requires the production, capture and stopping of muons at an unprecedented 10[sup 11][mu]/sec. If successful, such an effort would significantly advance the state of muon technology. More ambitious ideas for utilizing high intensity muon sources are also being explored. Building a muon storage ring for the purpose of providing intense high energy neutrino beams is particularly exciting. We present an overview of muon sources and example of a muon storage ring based Neutrino Factory at BNL with various detector location possibilities.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: By providing an intense, well controlled, well characterized, narrow beam of muon neutrinos (?????????s) and electron antineutrinos (–?e’s) from the decay of muons (?−??2019?s) in a storage ring, a neutrino factory can advance neutrino physics beyond the current round of approved and proposed experiments using conventional neutrino beams produced from a beam of decaying pions and kaons [1, 2]. There is no other comparable single clean source of electron neutrinos (from the decay of ?+’s) or antineutrinos. A muon storage ring producing 1019 to 1021 muon decays per year should be feasible. These intense neutrino beams can be used to study neutrino oscillations and possible CP violation. An entry-level muon storage ring that could provide 1019 decays per year would allow a determination of the sign of ?m231and a first measurement of sin22?13 for favorable values of this parameter. An improved muon storage ring system that could provide 1020 muon decays per year would allow measurement of sin22?13 to 1̃0−4. A high performance muon storage ring capable of providing more than 1020 muon decays per year would allow the exciting possibility of a measurement of CP violation in the leptonic sector. An intense cold muon beam at the front end of a neutrino factory could enable a rich variety of precision muon physics, such as a more precise measurement of the muon anomalous magnetic moment (g – 2) and searches for ? -> e ? and ?−N -> e− N conversion [3]. In addition, colliding beams of ?+ and ?− in a muon collider can provide an effective ?Higgs factory? or multi-TeV center-of-mass energy collisions [4]. A muon collider will be the best way to study the Higgs bosons associated with supersymmetric theories and may be necessary to discover them. Two neutrino factory feasibility studies have been carried out in the U.S. [5, 6]. International design efforts are now under way. The International Neutrino Factory and Superbeam Scoping Study (ISS) [7] began at the NuFact05 Workshop in June 2005 with the goals of elaborating the physics case, defining the baseline options for such a facility and its neutrino detectors, and identifying the required R&D program to lay the foundations for a complete design study proposal, and an International Design Study of the Neutrino Factory is beginning. These studies entail iterative cost and technical difficulty evaluations, thereby providing guidelines for the advancing R&D program. One of the central subsystems of a neutrino factory or muon collider is the muon cooling system. The muon beam is cooled to increase the phase space density and allow the muons to pass through smaller apertures, thus reducing the cost of the following accelerator systems. This cooling is accomplished through ionization cooling, in which the beam is passed through liquid hydrogen absorbers and then accelerated in RF cavities to restore the longitudinal momentum. Ionization cooling was proposed more than twenty years ago [8] but has not yet been demonstrated in practice. The International Muon Ionization Cooling Experiment (MICE) [9, 10] seeks to build and operate a muon-cooling device of a design proposed in Feasibility Study-II [6]. In addition to cooling the muons, MICE includes apparatus to measure the performance of the device. The experiment will be carried out by a collaboration of physicists from the U.S., Europe, and Japan at the Rutherford Appleton Laboratory in the U.K. MICE will begin operation in late 2007. Successful performance of the MICE experiment will provide the understanding needed to design a complete neutrino factory, in which the muons are cooled, accelerated, circulated in a storage ring, and decay to produce the neutrino beam. The first neutrino factory might be built in the U.S., Europe, or Japan. A Muon Collider Task Force (MCTF) has recently been organized at Fermilab.

Book excerpt: R & D aimed at the production, acceleration, and storage of intense muon beams is under way in the U.S., in Europe, and in Japan. Considerable progress has been made in the past few years toward the design of a ''Neutrino Factory'' in which a beam of 20-50 GeV mu- or mu+ is stored. Decay neutrinos from the beam illuminate a detector located roughly 3000 km from the ring. Here, we briefly describe the ingredients of a Neutrino Factory and then discuss the current R & D program and its results. A key concept in the design is ''ionization cooling, '' a process whereby the muon emittance is reduced by repeated interactions with an absorber material followed by reacceleration with high-gradient rf cavities. Plans to test this concept in the Muon Ionization Cooling Experiment (MICE) are well along and are described briefly.

Book excerpt: Muons are fundamental particles like electrons but much more massive. Muon accelerators can provide physics opportunities similar to those of electron accelerators, but because of the larger mass muons lose less energy to radiation, allowing more compact facilities with lower operating costs. The way muon beams are produced makes them too large to fit into the vacuum chamber of a cost-effective accelerator, and the short muon lifetime means that the beams must be reduced in size rather quickly, without losing too many of the muons. This reduction in size is called "cooling." Ionization cooling is a new technique that can accomplish such cooling. Intense muon beams can then be accelerated and injected into a storage ring, where they can be used to produce neutrino beams through their decays or collided with muons of the opposite charge to produce a muon collider, similar to an electron-positron collider. We report on the research carried out at the University of California, Riverside, towards producing such muon accelerators, as part of the Muon Accelerator Program based at Fermilab. Since this research was carried out in a university environment, we were able to involve both undergraduate and graduate students.
