Turner GENEVA 1990 CERN —Service d'Information scientifique — RD/799-2500-Avril 1990 - Ill - ABSTRACT The third version of the CERN Accelerator School's (CAS) advanced course on General Accelerator Physics was given at Uppsala University from 18-29 September, 1989. Its syllabus was based on the previous courses held in Oxford, 1985 and Berlin, 1987 whose proceedings were published as CERN Yellow Reports 87-03 and 89-01 respectively. However, the opportunity was taken to emphasize the physics of small accelerators and storage rings, lo present some topics in new ways, and to introduce new seminars. Thus the lectures contained in the present volume include chromatidty, dynamic aperture, kinetic theory, Landau damping, ion-trapping, Schottky noise, laser cooling and small ring lattice problems while the seminars include interpretation of numerical tracking, internal targets and living with radiation. - IV - - v - CERN ACCELERATOR SCHOOL UPPSALA UNIVERSITY will jointly organize a course on ADVANCED ACCELERATOR PHYSICS 18-29 SEPTEMBER 1989 at Hotel Linné, Uppsala, Sweden Lectures: Stochastic cooling Hamiltonian mechanics Electron cooling Liouville theorem Laser cooling Non-linear resonances Chromalicity Seminars Dynamic aperture Living with radiation Kinetic theory Radio-therapy Landau damping Compact synchrotron-light sources Lattice and lens design Interprétation of numerical tracking Longitudinal motion Internal targets Bunched-beam coherent instabilities Intensity limits in storage rings Wake fields Crystalline ion beams Introduction to polarisation Inlra-bearn scattering Interactions with residual gas Visits Ion trapping and clearing The Svedberg Laboratory Beam transfer function Mamie Siegbahn Institute Schottky noise on very cold beams Scanditronix AB General in forma I ion Students should have a basic knowledge of accelerators.

This is being carried oui principally by means of a biennial programme of basic and advanced two-week courses on general accelerator physics aiming to bridge the gap between the level of knowledge attained with a science or engineering degree and that required for starting accelerator research work. In addition, topical courses are organised jointly with the US Particle Accelerator School, while specialised courses and Workshops are staged as the need or opportunity arises and in conjunction with appropriate bodies or organizations. This policy has led to the vigorous programme of courses shown in the table below.
