High Rate Neutrino Detectors for Neutrino Factories

Three types of high rate neutrino detectors for neutrino interaction physics at neutrino factories are discussed. High performance general-purpose detectors might collect event samples on the order of a billion events or more. This could greatly improve on existing analyses of neutrino interactions and also lead to new and important analysis topics including, for example, precise determinations of the CKM matrix elements |Vub| and |Vcb|. The potential of such general purpose detectors is illustrated with reference to a detector, presented previously in reference hep-ex/9907033, that is structured around a novel and compact vertexing and tracking neutrino target comprising a stack of CCD pixel devices. Design ideas and prospects are also discussed for two types of specialized detectors: (i) polarized targets filled with polarized solid protium-deuterium (HD), for unique and powerful studies of the nucleon's spin structure, and (ii) Fully active liquid tracking targets with masses of several tonnes for precise determinations of the weak mixing angle, from the total cross-section for neutrino-electron scattering. All three detector types pose severe technical challenges but their utilization could add significantly to the physics motivation for neutrino factories.

High Rate Physics at Neutrino Factories

Both muon colliders and non-colliding muon storage rings using muon collider technology have the potential to become the first true ``neutrino factories'', with uniquely intense and precisely characterized neutrino beams that could usher in a new era of high rate and long baseline neutrino physics studies at accelerators. This paper gives an overview of the predicted capabilities of neutrino factories for high rate neutrino physics analyses that will use huge event samples collected with novel, high performance neutrino detectors.

Muon Colliders: the Ultimate Neutrino Beamlines

It is shown that muon decays in straight sections of muon collider rings will naturally produce highly collimated neutrino beams that can be several orders of magnitude stronger than the beams at existing accelerators. We discuss possible experimental setups and give a very brief overview of the physics potential from such beamlines. Formulae are given for the neutrino event rates at both short and long baseline neutrino experiments in these beams.

Potential Hazards from Neutrino Radiation at Muon Colliders

High energy muon colliders, such as the TeV-scale conceptual designs now being considered, are found to produce enough high energy neutrinos to constitute a potentially serious off-site radiation hazard in the neighbourhood of the accelerator site. A general characterization of this radiation hazard is given, followed by an order-of-magnitude calculation for the off-site annual radiation dose and a discussion of accelerator design and site selection strategies to minimize the radiation hazard.

Studies for Muon Colliders at Center-of-Mass Energies of 10 TeV and 100 TeV

Parameter lists are presented for speculative muon colliders at center-of-mass energies of 10 TeV and 100 TeV. The technological advances required to achieve the given parameters are itemized and discussed, and a discussion is given of the design goals and constraints. An important constraint for multi-TeV muon colliders is the need to minimize neutrino radiation from the collider ring.

Muon Colliders: New Prospects for Precision Physics and the High Energy Frontier

An overview is given of muon collider technology and of the current status of the muon collider research program. The exciting potential of muon colliders for both neutrino physics and collider physics studies is then described and illustrated using self-consistent collider parameter sets at 0.1 TeV to 100 TeV center-of-mass energies.

An All-Solid State Central Tracker for the Proposed DESY Electron-Positron Linear Collider

This report describes an all-solid state central tracker which is intended for use in a detector at the proposed DESY 500 GeV electron-positron linear collider or a similar accelerator. The precise position measurements from position-sensitive silicon detectors give the tracker an outstanding momentum resolution for high momentum tracks: sigma_p/p^2 = 3.6 x 10^{-5} (GeV/c)^{-1} for tracks perpendicular to the beam-line. The report concludes with an example layout for a detector which uses this central tracker.

Momentum Resolution Studies for a large TPC-Based Central Tracker

This note describes a study on the momentum resolution of the TPC-based central tracker design which will be included in the ECFA/DESY conceptual design report (CDR) for the proposed DESY 500 GeV electron-positron linear collider. The study found it to be likely that the central tracker could achieve a momentum resolution of approximately 10^{-4} (GeV/c)^{-1}, particularly if a layer of silicon microstrip detectors were to be added just inside the TPC.

Variable Field Bending Magnets for Recirculating Linacs

A lattice of single aperture superconducting variable field bending magnets is proposed as a cheap and practical way to recirculate the beams in recirculating linear accelerators. It is shown that the VFBM's can be configured to provide strong focusing in both transverse planes for the full range of beam momenta transported by the lattice.
