This self-contained textbook with exercises discusses a broad range of selected topics from classical mechanics and electromagnetic theory that inform key issues related to modern accelerators. Part I presents fundamentals of the Lagrangian and Hamiltonian formalism for mechanical systems, canonical transformations, action-angle variables, and then linear and nonlinear oscillators. The Hamiltonian for a circular accelerator is used to evaluate the equations of motion, the action, and betatron oscillations in an accelerator. From this base, we explore the impact of field errors and nonlinear resonances. This part ends with the concept of the distribution function and an introduction to the kinetic equation to describe large ensembles of charged particles and to supplement the previous single-particle analysis of beam dynamics. Part II focuses on classical electromagnetism and begins with an analysis of the electromagnetic field from relativistic beams, both in vacuum and in a resistive pipe. Plane electromagnetic waves and modes in waveguides and radio-frequency cavities are also discussed. The focus then turns to radiation processes of relativistic beams in different conditions, including transition, diffraction, synchrotron, and undulator radiation. Fundamental concepts such as the retarded time for the observed field from a charged particle, coherent and incoherent radiation, and the formation length of radiation are introduced. We conclude with a discussion of laser-driven acceleration of charged particles and the radiation damping effect. Appendices on electromagnetism and special relativity are included, and references are given in some chapters as a launching point for further reading. This text is intended for graduate students who are beginning to explore the field of accelerator physics, but is also recommended for those who are familiar with particle accelerators but wish to delve further into the theory underlying some of the more pressing concerns in their design and operation.

The Science of Musical Sound
49,99 € *
ggf. zzgl. Versand

This textbook is a product of William Bennett´s work in developing and teaching a course on the physics of music at Yale University to a diverse audience of musicians and science students in the same class. The book is a culmination of over a decade of teaching the course and weaves together historical descriptions of the physical phenomena with the author´s clear interpretations of the most important aspects of the science of music and musical instruments. Many of the historical examples are not found in any other textbook available on the market. As the co-inventor of the Helium-Neon laser, Prof. Bennett´s knowledge of physics was world-class. As a professor at one of the most prestigious liberal-arts universities in the world, his appreciation for culture and humanities shines through. The book covers the basics of oscillations, waves and the analysis techniques necessary for understanding how musical instruments work. All types of stringed instruments, pipe organs, and the human voice are covered in this volume. A second volume covers the remaining families of musical instruments as well as selected other topics. Readers without a background in acoustics will enjoy learning the physics of the Science of Musical Sound from a preeminent scientist of the 20 th century. Those well versed in acoustics will discover wonderful illustrations and photographs depicting familiar concepts in new and enlightening ways.

ggf. zzgl. Versand

An informative look at the theory, computer implementation, and application of the scaled boundary finite element method This reliable resource, complete with MATLAB, is an easy-to-understand introduction to the fundamental principles of the scaled boundary finite element method. It establishes the theory of the scaled boundary finite element method systematically as a general numerical procedure, providing the reader with a sound knowledge to expand the applications of this method to a broader scope. The book also presents the applications of the scaled boundary finite element to illustrate its salient features and potentials. The Scaled Boundary Finite Element Method: Introduction to Theory and Implementation covers the static and dynamic stress analysis of solids in two and three dimensions. The relevant concepts, theory and modelling issues of the scaled boundary finite element method are discussed and the unique features of the method are highlighted. The applications in computational fracture mechanics are detailed with numerical examples. A unified mesh generation procedure based on quadtree/octree algorithm is described. It also presents examples of fully automatic stress analysis of geometric models in NURBS, STL and digital images. * Written in lucid and easy to understand language by the co-inventor of the scaled boundary element method * Provides MATLAB as an integral part of the book with the code cross-referenced in the text and the use of the code illustrated by examples * Presents new developments in the scaled boundary finite element method with illustrative examples so that readers can appreciate the significant features and potentials of this novel method--especially in emerging technologies such as 3D printing, virtual reality, and digital image-based analysis The Scaled Boundary Finite Element Method: Introduction to Theory and Implementation is an ideal book for researchers, software developers, numerical analysts, and postgraduate students in many fields of engineering and science.

The A6 Ultra continues with the innovative concepts found in all Godin A-series guitars, such as combining amazing plugged-in acoustic sound with the feel of an electric neck, along with a chambered body design that virtually eliminates feedback in live & loud settings. These features stand true and better than ever in the A6 Ultra with the added ´´Oomph!” and full tone of a Godin humbucker in the neck position, along with an under-saddle transducer, dual outputs (acoustic and electric) that combine for a huge sound and a Custom Godin preamp section voiced specifically for the A6 Ultra. This preamp section gives a player the chance to control their tone via sliders for acoustic volume, treble, mid, bass and independent controls for the electric humbucker volume, treble and bass. Whether plugging into the single acoustic mix or via both outputs, controlling your tone is at the tip of your fingers. And the A6 Ultra delivers in all styles of music from jazz to rock to country and not to mention a great blues slide guitar.SpecsMahogany neckRosewood Fingerboard16 fingerboard radius25 1/2 Scale1 11/16 nut widthChamber Silver Leaf Maple bodySolid Cedar TopGodin GHN1 HumbuckerCustom Godin under Saddle Transducer and custom preamp with Volume, Mid, Treble and Bass controls as well as independent volume, treble and bass controls for the Humbucker.2 output jacks: electric & acoustic mix

The ACS blends classical guitar concepts with elements of solid body design. The incredibly comfortable neck from the Multiac Nylon is used here with a Maple body to achieve our most affordable synth access guitar ever. Although the body is chambered, response from the maple top is more typical of a solid body design than that of a traditional acoustic guitar. This design results in an instrument that is virtually free of feedback, making it easy to use even when the band gets loud.The engine in both the ACS-SA & ACS-SA Slim includes individual transducer saddles powered by a customized preamp system from the RMCTM Pickup Company. This system not only produces superb amplified sound, but also produces a hexaphonic output through a 13-pin connector enabling direct access to RolandTM GR-Series guitar synthesizers.SpecsMahogany neckEbony Fingerboard16 fingerboard radius25 1/2 Scale1 7/8 nut widthChambered Silver Leaf Maple bodyCustom RMC electronics with 13-pin connector for direct control of Roland GR Series and Axon AX100 guitar synths
