CAS - CERN Accelerator School: Accelerators for Medical Applications: Vösendorf, Austria 26 May - 5 Jun 2015

These proceedings collate lectures given at the course on Accelerators for Medical Applications, organised by the CERN Accelerator School (CAS). The course was held at the Eventhotel Pyramide, V\"osendorf, Austria from 26 May to 5 June, in collaboration with MedAustron. Following introductory lectures on radiobiological and oncological issues, the basic requirements on accelera- tors and beam delivery are reviewed. The medical applications of linear accelerators, cyclotrons and synchrotrons are then be treated in some detail, followed by lectures on the production and use of radioisotopes and a look at some of the acceleration techniques for the future.
