During those years, the book has gone through several phases starting with the two volume edition 1 and 2. Finally in 2007, both volumes and the book on SynchrotronRadiation have been combinedintotheThird-Editionasonevolumetoserveasatextbookforstudents andbeginnersaswellasareferencebookforthepractitioners.Nowithasbecome necessaryto reviewthetextandupgradeto includenewdevelopments.Italso has become apparentthat the decision for the Third-Edition to eliminate introductory accelerator physics was not correct. Use of this text for beginners is quite broad, and the introduction to accelerator physics is desired. Therefore, three chapters have been added at the beginning to introduce a variety of accelerators and their functioning.Insupporttoteaching,manyproblemswithsolutionshavebeenadded forthosechapters.Theauthoralsotriedtodistinguishbetweenintroductorychapters andchapterswhichleadtomoredetailedsubjectsandshowproofs.Chapterswhich canbeskippedonafirstreadinghavebeenlabeledwithastar(cid:2): Asmentioned,thetextincludesmanyproblemswithandwithoutsolutions.The idea was to give solutions for the beginners while more advanced problems are not suitable for solutions in a textbook. Accelerator physics is not a collection of homework problems. Many questions and problems are rather complex and need to be treated in context with their impact on other systems. In most cases, thereisnooneoptimumsolution.Individualparameterchoicesmustbemadeand modified according to their impact on other systems. Choices in beam dynamics, for example, have an impact on magnet design or RF-system parameters, etc. affectingthe design of power suppliesor financialbudget. Straightforwarddesign choicespermeatethroughalmostallothercomponentsrequiringcarefulevaluation. Often the consequence of one parameter choice on other systems will become apparent only after considerable further design optimization. Unfortunately,often compromisesmustbemadebecauseoffinancialconsiderations.Workinaccelerator physicsincludesoftenseveralapproximations,andthedesignershouldnothesitate tostartoveragainwithnewinsight.Allthiscannotbeincludedinproblemsolutions inatextbook.However,itseemedtotheauthorinterestingtothrowupsuchdesign problemswhichtheinterestedreadercanusetomakehis/herchoices. vii viii PrefacetoFourthEdition Finally,inthelastchapteronFreeElectronLasers,ashortintroductionintothe componentsofa SASE-FEL facility is given.Thisintroductionmustbe shortand limited to the discussion of issues and function of main components in this text.
