Accelerator physics, 4th edition

The field of accelerator physics is a fast-moving and dynamics field, drivingmany of the scientific discoveries that recent years have brought. In any broad field such as this, there tend to be the definitive textbooks, the go-to source for a student or a researcher of any level. These books tend to define the field’s language and conventions and referred to by prettymuch every training course. In accelerator physics, the textbooks of S. Y. Lee are one of those books. Accelerator Physics by S. Y. Lee is now in its 4th edition and can be found on bookshelves and libraries around the world. The book is written in a rigorous and complete style, thus satisfying professional scientists and savvy graduate students, but also manages to be good at explaining and introducing the basic concepts. A particular strength is the level of physical insight offered by the author. The book is primarily aimed towards people working the field, from PhD students upwards, but would serve as a useful introduction for an enthusiastic undergraduate. The material is complete, from the basic derivations of the equations of motion of particles in accelerators to non-linear motion and an impressive range of advanced concepts. The layout of the book is as follows and fairly standard. After a very readable introduction, there is a very detailed and long section on transverse dynamics. This covers all the standard material, plus some advanced materials. This section on transverse dynamics is excellent. This is followed by longitudinal dynamics (again excellent), the physics of storage rings (with synchrotron radiation and equilibrium emittance) and concludes with a section on free electron lasers (FELs) and beam-beam physics. There are useful appendices on classical dynamics and numerical methods. The range and depth of coverage are excellent. The 4th edition is an expansion of topics and a general update, with an expansion of FEL coverage. There are many problems to consolidate understanding and plenty of wisdom in the pages. This book is ideally suited to a worker in the field who would like to keep up with the latest thinking and get a deep understanding of the field. Personally speaking, as an accelerator physicist, this is one of my favourite textbooks and is as definitive as they come.
