Book excerpt: We present a candidate design for a high-energy high luminosity [mu][sup +]-[mu] collider, with E[sub cm] = 4 TeV, L = 10[sup 34] cm[sup [minus]2]S[sup [minus]1], using only existing technology. The design uses a rapid-cycling medium-energy proton synchrotron, which produces proton beam pulses which are focused onto two [pi]- producing targets, with two [pi]-decay transport lines producing [mu][sup +][prime]s and [mu][sup [minus]][prime]. The [mu][prime]s are collected, rf-rotated, cooled and compressed into a recirculating linac for acceleration, and then transferred into a storage ring collider. The keys to high luminosity are maximal [mu] collection and cooling; innovations with these goals are included.

We derive an expression for the luminosity in terms of analytic formulae for the electron-to-muon conversion efficiency and the electron beam power on the production target On the basis of studies of self-consistent sets of collider parameters under 'realistic' ('optimistic') assumptions about available technology with beam cooling, we find the luminosity limited to 1027 m−2s−1 (1028 m−2s−1). We also identify major technological innovations that will be required before?+?− colliders can offer sufficient luminosity (103° cm−2s−1) for high energy physics research.

Available in PDF, EPUB and Kindle. Book excerpt: The authors discuss the problem of transforming muon beam bunches from a low-energy cooled state (E[sub[mu]][approximately] 1 GeV) to short, high-energy bunches matched to high-energy collision conditions (E[sub[mu]][approximately] 2 TeV). In this process the beam energy must increase by[approximately] three orders of magnitude, while the bunch length must be reduced by[approximately] two orders of magnitude (to[approximately] 3mm), while beam emittance dilution and beam losses, particularly through decay, must be minimized. From general considerations, they discuss possible acceleration scenarios including rapid-cycling synchrotron and recirculating linac options. The presently favored choice is a multi-stage recirculating linac system, which is discussed, and initial simulations of possible scenarios are presented. Future directions for development are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The rich physics potential of a high-energy high-luminosity[mu][sup+][mu][sup[minus]] collider and the surprising feasibility of a design attract the attention of many people these days. A few issues define the practicality of such a project, with the enormous particle background levels in a detector due to unavoidable reasons holding first place. In contrast to hadron colliders where particle backgrounds come both from interaction point (IP) and accelerator, almost all the backgrounds in the muon collider detectors arise in the machine. The decay length for 2 TeV muons is[lambda][sub D][sup[minus]1][approximately]10[sup[minus]7] m[sup[minus]1]. With 10[sup 12] muons in a bunch one has 10[sup 5] decays per meter in a single pass through an interaction region, and 10[sup 8] decays per meter per 12 msec store. This paper examines two major classes of detector backgrounds presented in the muon collider: beam halo backgrounds, and the[open-quotes]direct[close-quotes] backgrounds from electrons from[mu][yields]e[nu][bar[nu]] decay occurring in the beam channel. The authors describe the nature of both of these backgrounds, provide results of first realistic calculations for both sources and discuss their effects on plausible detectors. Various shielding and collimation geometries have been simulated, and their efficacy and the nature of the surviving background discussed.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A calculational approach is described to study beam induced radiation effects in detector and storage ring components at high-energy high-luminosity[mu][sup+][mu][sup[minus]] colliders. The details of the corresponding physics process simulations used in the MARS code are given. Contributions of electromagnetic showers, synchrotron radiation, hadrons and daughter muons to the background rates in a generic detector for a 2 x 2 TeV[mu][sup+][mu][sup[minus]] collider are investigated. Four configurations of the inner triplet and a detector are examined for two sources: muon decays and beam halo interactions in the lattice elements. The beam induced power density in superconducting magnets is calculated and ways to reduce it are proposed.

Book excerpt: Radiation issues of high-luminosity 2 x 2 TeV and 250 x 250 GeV[mu][sup+][mu][sup -] colliders are considered. A series of dedicated simulations have been performed with the MARS code to understand formation of radiation fields in the complex and to assure that there are ways to meet the stringent regulation requirements. Considered in detail are the main collider arcs, the interaction region and absorption of spent muon beam. Prompt and residual radiation is analyzed. It is shown that for both operational and accidental beam loss radiation problems appear quite solvable.

Book excerpt: High energy colliding beam machines for elementary particle research have grown so costly that funding for them has become problematical. The physics they would explore, however, remains compelling, so that new methods must be found to reach high energy if this physics is to be studied. One such new approach is the muon collider. This machine could reach multi-TeV collision energies with good luminosity at an affordable cost. The scenario for producing[mu][sup+][mu][sup[minus]] collisions is shown schematically in a figure. A high intensity proton synchrotron delivers protons in sharply defined bunches onto a stationary target with an energy of 30 GeV. Many pions are produced that decay into muons; both are collected in a solenoid magnet system with useful energies in the range 0.1--1.0 GeV. The muons are then cooled, i.e. their transverse momentum as well as the spread in their longitudinal momentum is reduced. In this way, a bunch of protons is turned into a bunch of positive or negative muons suitable for acceleration and collision. The energy of the muons at this stage is only 0.02 GeV. Acceleration is accomplished in a series of recirculating linac accelerators, similar to the approach used in CEBAF. Upon reaching 2,000 GeV (2 TeV) of energy, the muons are transferred into a ring where positive and negative muons, transferred in successive bunches, collide and the collisions studied in a suitable detector. About 25% of the muons originally collected survive into the collider ring, and here they live for an average of[approximately] 1,000 revolutions. At this point, the surviving muons are dumped and new bunches are injected. This paper describes in abbreviated form the main features and parameters of the presently envisioned muon collider, most of it taken from the latter two reports.

Book excerpt: An important feature of a[mu]-storage ring[nu]-source is that it can be extended to the possibility of a future high-energy muon collider. The neutrino source provides a useful physics device that initiates key technologies required for future[mu][sup+]-[mu][sup[minus]] Colliders, but with much less demanding parameter requirements. These technologies include high-intensity[mu]-production, [mu]-capture, [mu]-cooling, [mu]-acceleration and multiturn[mu] storage rings.[mu][sup+]-[mu][sup[minus]] colliders require a similar number of muons, but they require that the muons be cooled to a much smaller phase space and formed into a small number of bunches, and both positive and negative bunches must be simultaneously captured. These differences are discussed, and the extension of the[nu]-source to[mu][sup+]-[mu][sup[minus]] collider specifications is described.
