      Conference report
      Open Access
      Heating with ICRF waves is a well-established method on present-day tokamaks and one of the heating systems foreseen for ITER. However, further work is still needed to test and optimize its performance in fusion devices ...

    • Computational analysis of ion cyclotron resonance frequency heating for DEMO 

      Gallart Escolà, Dani (Universitat Politècnica de Catalunya, 2015-06)
      Master thesis
      Open Access
      Ion cyclotron resonance frequency heating (ICRH) is one of the most important mechanisms to heat fusion plasma. The magnetic field generated by the magnetic coils forces ions to follow a cyclotron trajectory around the ...

      Soriano Baguet, David (Universitat Politècnica de Catalunya, 2017-06-15)
      Master thesis
      Open Access
      The ITER project was created with the goal of showing the world that fusion energy is possible and can be a major step towards having a whole new kind of commercial reactors in the energy sector. Fusion energy is obtained ...

    • Effect on the Tritium Breeding Ratio for a distributed ICRF antenna in a DEMO reactor 

      Garcia Perez, Albert (Universitat Politècnica de Catalunya, 2015-09)
      Master thesis (pre-Bologna period)
      Restricted access - author's decision
      This thesis reports results of MCNP-5 calculations, with the nuclear data library FENDL-2.1, to assess the effect on the Tritium Breeding Ratio (TBR) when integrating a distributed Ion Cyclotron Range of Frequencies (ICRF) ...

    • Experimental techniques in determination of electron cyclotron power deposition profiles in thermonuclear plasmas
