Free-Electron Lasers in the Ultraviolet and X-Ray Regime - Physical Principles, Experimental Results, Technical Realization... Free-Electron Lasers in the Ultraviolet and X-Ray Regime - Physical Principles, Experimental Results, Technical Realization (Hardcover, 2nd ed. 2014)
Peter Schmuser, Martin Dohlus, Joerg Rossbach, Christopher Behrens
R4,458 Discovery Miles 44 580 Ships in 10 - 15 working days

The main goal of the book is to provide a systematic and didactic approach to the physics and technology of free-electron lasers. Numerous figures are used for illustrating the underlying ideas and concepts and links to other fields of physics are provided. After an introduction to undulator radiation and the low-gain FEL, the one-dimensional theory of the high-gain FEL is developed in a systematic way. Particular emphasis is put on explaining and justifying the various assumptions and approximations that are needed to obtain the differential and integral equations governing the FEL dynamics. Analytical and numerical solutions are presented and important FEL parameters are defined, such as gain length, FEL bandwidth and saturation power. One of the most important features of a high-gain FEL, the formation of microbunches, is studied at length. The increase of gain length due to beam energy spread, space charge forces, and three-dimensional effects such as betatron oscillations and optical diffraction is analyzed. The mechanism of Self-Amplified Spontaneous Emission is described theoretically and illustrated with numerous experimental results. Various methods of FEL seeding by coherent external radiation are introduced, together with experimental results. The world s first soft X-ray FEL, the user facility FLASH at DESY, is described in some detail to give an impression of the complexity of such an accelerator-based light source. The last chapter is devoted to the new hard X-ray FELs which generate extremely intense radiation in the Angstrom regime. The appendices contain supplementary material and more involved calculations."

Penis Pokey (Board book): Christopher Behrens Penis Pokey (Board book)

This book contains no nudity. No profanity. No sexual material of any kind. And yet it just might be the most obscene thing we've ever published!

"Penis Pokey" is an illustrated board book with a large die-cut hole in its center. Every spread features a dazzling full-color illustration with one thing missing a banana, perhaps, or a fire hose, or a sea serpent. Male readers can complete the illustrations using the talents God has given them.

Are we serious? Yes! Is this funny? Absolutely! Will this be a terrific hit with college students, bachelorette parties, and exhibitionists of all ages? Of course! "Penis Pokey" is far and away the strangest and funniest novelty book we've seen in a long, long time.

Chaos in the Contact Zone - Unpredictability, Improvisation, and the Struggle for Control in Cultural Encounters (Paperback):... Chaos in the Contact Zone - Unpredictability, Improvisation, and the Struggle for Control in Cultural Encounters (Paperback)
Christoph Behrens, Stephanie Wodianka
R1,013 Discovery Miles 10 130 Ships in 12 - 17 working days

Cultural encounters are often being stylized not only as experiences of uncontrollability and unpredictability par excellence, but also as challenges to planning and predicting. The history, the different forms and the consequences of this phenomenon are the main issues discussed in this volume. The contributions show that chaos and control are not mutually exclusive in the "contact zone" (Mary Louise Pratt); on the contrary, they stand in relation to each other - be it as a competence or as an interpretive scheme.
