Book excerpt: This paper presents a concise summary of the developments achieved in the context of the ''Photons'' Working Group of the 1991 ECFA Workshop on Physics with Linear Colliders. After reviewing, in Section 2, the current knowledge on the beam-beam interaction and its main physics implications, they calculate in Section 3 effective photon and electron luminosity spectra. Section 4 discusses background issues associated with photon-photon processes. Finally, they briefly survey, in Section 5, recent updates on the principle issues and the physics potential of the so-called ''Compton Collider''.

Book excerpt: Three major effects from the interaction of ee/sup /minus// beams--disruption, beamstrahlung, and electron-positron pair creation--are reviewed. For the disruption effects we discuss the luminosity enhancement factor, the maximum and rms disruption angles, and the ''kink instability''. All the results are obtained from computer simulations. Scaling laws for the numerical results and theoretical explanations of the computer acquired phenomena are offered wherever possible. For the beamstrahlung effects we concentrate only on the final electron energy spectrum resulting from multiple photon radiation process, and the deflection angle associated with low energy particles. For the effects from electron-positron pair creation, both coherent and incoherent processes of beamstrahlung pair creation are discussed. In addition to the estimation on total number of such pairs, we also look into the energy spectrum and the deflection angle. 17 refs., 23 figs., 1 tab.

Book excerpt: The limit in hadron colliders is understood phenomenologically. The beam-beam interaction produces nonlinear resonances and makes the transverse tunes amplitude dependent. Tune spreads result from the latter, and as long as these tune spreads do not overlap low order resonances, the lifetime and performance is acceptable. Experience is that tenth and sometimes twelfth order resonances must be avoided, and the hadron collider limit corresponds roughly to the space available between resonances of that and lower order when operating near the coupling resonance. The beam-beam interaction in ee− colliders is not understood well. This affects the performance of existing colliders and could lead to surprises in new ones. For example. a substantial amount of operator tuning is usually required to reach the performance limit given above, and this tuning has to be repeated after each major shutdown. The usual interpretation is that colliding beam performance is sensitive to small lattice errors, and these are being reduced during tuning. It is natural to ask what these errors are, how can a lattice be characterized to minimize tuning time, and what aspects of a lattice should receive particular attention when a new collider is being designed. The answers to this type of question are not known, and developing ideas for calculations, simulations and experiments that could illuminate the details of the beam-beam interaction was the primary working group activity.

Book excerpt: High energy photon - photon collisions can be achieved by adding high average power short-pulse lasers to the Linear Collider, enabling an expanded physics program for the facility. The technology required to realize a photon linear collider continues to mature. Compton back-scattering technology is being developed around the world for low energy light source applications and high average power lasers are being developed for Inertial Confinement Fusion.

Book excerpt: Beamstrahlung is the fraction energy loss to radiation as one beam pulse is accelerated by the electromagnetic field of the other pulse through which it passes in a collider. In linear colliders the individual pulses must be formed with much larger charge densities to compensate for their much lower rate of interactions (102 -- 103 per second) in comparison to storage rings (typically 105 per second). Therefore the electromagnetic fields generated by the charges in each pulse will be correspondingly larger, as will the acceleration they induce in the charges of the intersecting pulses; this in turn leads to a larger loss of energy to radiation. In this report we consider three questions: What is the quantum result for beamstrahlung and when is the classical result valid. How does the transverse beam geometry--i.e., ribbon versus cylindrical pulse--affect the beamstrahlung. Extending the quantum calculation to multiple photon emission, what is the photon flux and what are the prospects for a photon-photon collider. 3 refs., 2 figs.

Available in PDF, EPUB and Kindle. Book excerpt: The intense radiation, called beamstrahlung, during the collision of ee− beams in a linear collider, is reviewed, with attention to the influence of beam-beam disruption on the beamstrahlung spectrum. We then discuss the various detector backgrounds induced by these hard beamstrahlung photons, as well as the Weiszacker-Williams photon, through various QED and QCD processes, namely the coherent and incoherent ee− pair creation and the hadron production and minijet yields.

Available in PDF, EPUB and Kindle. Book excerpt: Photon-photon interactions have been an important probe into fundamental particle physics. Until recently, the only way to produce photon-photon collisions was parasitically in the collision of charged particles. Recent advances in short-pulse laser technology have made it possible to consider producing high intensity, tightly focused beams of real photons through Compton scattering. A linear e{sup +}e{sup -} collider could thus be transformed into a photon-photon collider with the addition of high power lasers. In this paper they show that it is possible to make a competitive photon-photon collider experiment using the currently mothballed Stanford Linear Collider. This would produce photon-photon collisions in the GeV energy range which would allow the discovery and study of exotic heavy mesons with spin states of zero and two.
