Abstract
Magnets are the components devoted to focus and steer the beam in particle accelerators. Several beam properties such as spot size, emittance, centroid position, etc. as well as the dynamic aperture in the circular accelerators are strictly correlated to the quality of the magnetic field. Therefore an accurate magnet design is fundamental to have a good accordance between the ideal beam parameters and the real ones. Moreover, for electromagnets, the performance of the magnet is closely related to the power supply (PS), in fact though a magnet has been properly designed, if the PS performances are out of specifications the resulting magnetic field will not be compliant with the requirements. This will led to a beam properties degradation or to a huge reduction of beam life-time. This work cover all the aspects of the normal conductive and permanent magets design for particle accelerators, their manufacturing, their perfomance check through magnetic measurements. Moreover also the measurements of magnets power supplies is one of the topic of this work. The work for this dissertation is described in a total of three chapters. Chapter 1 describes the Frascati accelerator complex, focusing on the present configuration and on the upgrade of the beam test facility (BTF). The magnetic design of two type of dipoles will be detailed together with a presentation of all the manufacturing phases and magnetic measurements. In chapter 2 physics of the Compton backscattering is introduced with a general overview of the Compton sources and their wide range of applications. In this scenario the main parameters of the European ELI-NP-GBS project, its current layout and the linac parameters will be presented . Then an overview of the magnets and power supplies will be given together with the test performed on the magnets and on the power supplies. In chapter 3 the SPARC_LAB test facility is presented, focusing on the PWFA module and its actual beam focusing system. In the end, the magnetic design of the proposed new tunable permanent magnet quadrupole will be given also with the support of all the 2D and 3D simulation results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
