[en] Antiprotons emerge from the target, along with many other fundamental particles, and are focused by a cylindrical lens, called a magnetic horn, into the beam transport system. The latter consists of an arrangement of strong focusing quadrupoles and a spectrometer magnet. (orig./HSI)

[en] The use of a molecular gas 'jet' as an internal target in a storage ring is described. (orig.)

[en] We examine a few typical examples related to proton or antiproton storage rings. (orig./HSI)

[en] The purpose of beam optics is essentially the study of the transverse phase space which is the set of the coordinates of position and velocity of a particle in a plane normal to reference trajectories. The course is limited to the study of particle trajectories in a static magnetic field and to small amplitude oscillations. In addition, the oscillations are assumed to be uncoupled between the horizontal and vertical directions. In the first part, elements of exact beam optics in a magnet and the transfer of a single particle are treated. In the second part, the concept of beam transfer is introduced with a review of Courant and Snyder theory of betatron oscillations. The last section is devoted to the local properties of the closed orbits when the momentum is varied in order to lay the basis for the study of the longitudinal phase space which is the set of the time and energy coordinates of a particle.

[en] All the non interacting monitors used for the p-anti p instrumentation can be related to the use of the wall image current as induced by relativistic charged particle bunches circulating in a metallic pipe or vacuum chamber. The monitors are then classified by their type of beam coupling impedance. This allows a more generalized approach of the design of the so-called pickups. (orig./HSI)

[en] Some experimental data on the beam-beam effect in e⁺e^- and p-pbar colliders are presented in order to illustrate their differences and similarities. Then, after treating the linear beam-beam force, the subject of nonlinear resonances are introduced using some simple examples. (orig./HSI)

[en] In this paper, the conditions leading to the accumulation of ions are established for various cases of bunched beams, together with the maximum ion density which can be reached. An application to the SPS panti p collider is also given. (orig./HSI)

[en] The author describes the equipment and methods for stochastic cooling. (HSI)

[en] This is a specialized course which addresses a wide spectrum of theoretical and technological problems confronting the designer of an antiproton facility for high-energy-physics research. A broad and profound basis is provided by the lecturers' substantial experience gained over many years with CERN's unique equipment. Topics include beam optics, special lattices for antiproton accumulation and storage rings, antiproton production, stochastic cooling, acceleration and storage, r.f. noise, r.f. beam manipulations, beam-beam interaction, beam stability due to ion accumulation, and diagnostics. The SPS (Super Proton Synchrotron) panti p collider, LEAR (the Low Energy Antiproton Ring at CERN), antiprotons in the ISR (Intersecting Storage Rings), the new antiproton collector (ACOL) and gas jet targets are also discussed. A table is included listing the parameters of all CERN's accelerators and storage rings. See hints under the relevant topics. (orig./HSI)

[en] These two lectures have been prepared to give a simple introduction to the principles. In Part I we try to explain stochastic cooling using the time-domain picture which starts from the pulse response of the system. In Part II the discussion is repeated, looking more closely at the frequency-domain response. An attempt is made to familiarize the beginners with some of the elementary cooling equations, from the 'single particle case' up to equations which describe the evolution of the particle distribution.
