Linacs / Lombardi, Alessandra (speaker) (CERN)
In this lecture we review the fundamental principles of a linear accelerator, we look at different types of RF structures both in the TE and TM mode and we discuss their use at different velocities and/or charge over mass. We also discuss basic principles of dynamics (transverse and longitudinal phase advance) during acceleration. [...]

Cryogenics / Koettig, Torsten (speaker) (CERN)
Cryogenics is the field of physics and engineering that deals with the production and effects at very low temperatures. The Large Hadron Collider (LHC) is the largest cryogenic system in the world and one of the coldest places on Earth. [...]

RF Systems / Damerau, Heiko (speaker) (CERN)
Radio-frequency (RF) systems deliver the power to change the energy of a charged particle beam, and they are integral parts of linear and circular accelerators. A longitudinal electrical field in the direction of the beam is generated in a resonant structure, the RF cavity. [...]

Longitudinal Beam Dynamics II / TECKER, Frank (speaker) (CERN)
Please see "Longitudinal Beam Dynamics I" for the complete set of slides. "The lectures present an introduction to longitudinal beam dynamics on a basic level, focused rather on the concepts than the mathematical details. It covers the basic methods of acceleration in a linac, presents different circular accelerator types, and focuses more on the longitudinal beam dynamics in synchrotrons. The operation principle of synchrotrons is described, synchrotron oscillations in energy and phase are discussed, together with their representation in phase space, and their stability conditions presented. The lecture also shows the importance of a proper matching of the longitudinal parameters when the beam is transferred from one accelerator to the next. Finally, the RF manipulations in the PS for the generation of the bunch structure of the LHC beam are explained..

Vacuum Systems / Baglin, Vincent (speaker) (CERN)
Vacuum systems are an intrinsic part of any accelerators around the world: all particles are circulating under vacuum. This lecture gives rudiments on fundamentals of vacuum science such as units, ideal gas law, partial pressure, mean free path, flow of molecules, conductance, pumping speed and outgassing. [...]

Linear Imperfections / Wenninger, Jorg (speaker) (CERN)
A real accelerator may deviate significantly with respect to the ideal model due to manufacturing and installation uncertainties. Such deviations or imperfections impact many aspects like machine apertures, optics quality and performance, and they must be corrected to limit or minimize their impact of the beam. [...]

Superconducting Magnets / Todesco, Ezio (speaker) (CERN)
In this lecture we first discuss the requirements of the magnets in terms of aperture and beam size, the relations between dipole field and accelerator energy, and conditions of beam stability on the quadrupole gradient. We then show how the superconducting technology enables a technological leap, with current densities in the windings 100 times larger than what can be achieved with resistive conductors [...]

Injection and Extraction / Dutheil, Yann (speaker) (CERN)
The storage and acceleration of particles in a synchrotron are typically limited to a range of energy, or magnetic rigidity, of a factor 15. Therefore, to accelerate protons from the 200 MeV Linac 4 to the 7 TeV it comes that a chain of at least 4 such synchrotrons is needed. The injection and extraction of beams between accelerators are essential to achieve a wide range of energies and a beam specification. This lecture presents injection and extraction techniques used for synchrotrons and across the CERN complex. [...]
