The book is devoted to processes at the interaction of high energy charged particles and photons with crystals. Among them are the creation of electron-positron pair by photon in crystalline field, the radiation of particles in this field and, connected with these effects, the new type of electromagnetic showers in crystals, the channeling of fast particles in crystal and channeling radiation. At high energies, the processes of quantum electrodynamics (QED) in intense external fields play an important role in crystals. The first third of the book contains a new formulation of QED in external fields which is valid for any external field, including an essentially nonuniform one and has vast applications.

The book "Channeling 2008", Charged and Neutral Particles Channeling Phenomena, is formed by the same title conference contributions. This volume includes papers by leading researchers from different world centers. Their recent results on the coherent phenomena of charged and neutral particles propagating through the structures of various sizes and periodicities are included here, along with historical reviews by pioneers of coherent Bremsstrahlung and channeling radiation as well as crystal channeling collimation.

Proceedings of SPIE present the original research papers presented at SPIE conferences and other high-quality conferences in the broad-ranging fields of optics and photonics. These books provide prompt access to the latest innovations in research and technology in their respective fields. Proceedings of SPIE are among the most cited references in patent literature.
