RF power and signal transmission in particle accelerators

Abstract

RF waves have key applications for particle accelerators in transmitting both sig nal and power. In this thesis, we summarize work covering both of these complementary functions of the RF waves, applied to two separate projects. One of the projects is the design and construction of an RF transmission line and circulator at the KAHVE Laboratory of Bo˘gazic¸i University. As part of this project, we describe simulations and characterization measurements of various power transmission line components running at 800 MHz. The second project is about the developing a methodology that would al low in-situ determination of the presence of previously installed shields used in bellows connected to beam pickup monitors on the CERN SPS accelerator, and confirmation of whether their performance is adequate in eliminating 1.3GHz intrinsic resonance aris ing from the limits of the longitudinal beam coupling impedance. For both projects, detailed simulations have been performed and compared to the measurements and the obtained results are in line with the project targets.
