Longitudinal BD in Circular Machines II
/ Tecker, Frank (speaker) (CERN)
The lectures present an introduction to longitudinal beam dynamics for circular accelerators.
It presents different circular accelerator types (betatron, cyclotron, synchrocyclotron, synchrotron), 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.
The lecture discusses the equations of motion, the stability conditions for the longitudinal oscillations, and introduces the Hamiltonian of longitudinal synchrotron motion.
It also explains the bunch transfer from one accelerator to the next and shows the importance of a proper matching of the longitudinal parameters.
Finally, the RF manipulations in the PS for the generation of the bunch structure of the LHC beam are explained..

Time and Frequency domain signals II
/ Schmickler, Hermann (speaker)
Depending on the application people use time-domain or frequency domain signals in order to measure or describe processes. First we will look at the definition of these terms, produce some mathematical background and then apply the tools to measurements made in the accelerator domain. [...]

Beam Diagnostics
/ Forck, Peter (speaker)
The working principle of frequently used beam instruments for electron and proton beams concerning the transverse and longitudinal profile measurement is discussed. A large variety of monitors for transverse profile measurement exists, based on the energy loss of the beam particles in matter followed by the detection of secondary particles or photons (SEM-Grids, wire scanners, scintillation screens, optical transition radiation screens, ionization profile monitors). [...]

Colliders and luminosity
/ Schmickler, Hermann (speaker)
Modern particle physics relies on high energy particle accelerators to provide collisions of various types of elementary particles in order to deduce fundamental laws of physics or properties of individual particles. The only way to generate particle collisions at extremely high energies is to collide particles of counter-rotating beams...called "particle-colliders". [...]

Linear Imperfections - corrections
/ Ziemann, Volker (speaker)
We introduce the BPM-corrector response coefficient R12 as the key quantity
to characterise the effect of imperfections on the beam dynamics before
addressing how the effect of multiple imperfections are combined. We then
introduce local beam bumps as a means to adjust the beam position locally
and move on to discuss orbit correction and the orbit response matrix.
We place special attention to different methods, including singular value
decomposition, to invert the response matrix. [...]
