Course Information
Contents:
The course contains four parts:
-Transmission line theory: This part is an extension of the theory given in the basic courses in the electromagnetic theory (EF for F and Pi and EF for E). There is a slight overlap with the course in radio electronics. This part also includes a laboratory practical where the students do measurements with network analyzers.
-Waveguide theory: The theory for wave propagation of electromagnetic fields in different types of waveguides. Determination of power flow, attenuation, phase and group speeds using analytic and numerical methods. The finite element method is used for numerical simulations.
-Microwave cavities: The basic theory for cavities. Analytic methods for determination of resonance frequencies, eigenfields and Q-values for microwave cavities with simple geometries. Determination of the same quantities for cavities with more complicated geometries using the finite element method. The course describes how microwave cavities transfer energy from electromagnetic fields to kinetic energies of the particles in particle accelerators.
-Optical fibers: The theory for the single- and multi-mode fibers is presented. The finite element method is used for numerical simulations.
Many of the applications will be towards the accelerators that are to be used at ESS and MaxIV. These accelerators rely on waveguides to transport power and on resonating cavities in order to accelerate the charged particles (electrons in MaxIV and protons in ESS). There will be a visit to Maxlab in the course.
Examination:
Hand in problems, a small project and an oral presentation of the project. For highest grade (5) an oral examination is required.
ESS and MaxIV
The research field of particle accelerators has during the last years grown strong in Lund since the two very large research plants MaxIV and ESS will be built here. Microwave technique is extremely important for accelerators and it is vital that Lund university supplies these plants with engineers and physicists that know microwave theory and technique. For this reason the course in microwave theory focuses on applications that are relevant for particle accelerators. The aim is that the students that have passed the course will know enough microwave technique in order to do a master thesis project or to become an employee or PhD student at ESS or Maxlab.
