Analysis of energetic particle-driven Alfvénic instabilities in tokamak and stellarator plasmas using three dimensional numerical tools

Rakha, Allah (Date of defense: 2019-09-27)

In this thesis, a detailed analysis of the experientially observed energetic particle-driven Alfvénic instabilities in tokamak and stellarator plasmas using three dimensional numerical tools based on the reduced MHD model ...

Computational analysis of ion cyclotron resonance frequency heating for JET experiments

Gallart Escolà, Dani (Date of defense: 2019-09-27)

Heating plasmas to a relevant fusion temperature is one of the key aspects of magnetically confined fusion plasmas. Radio frequency (RF) heating with electromagnetic waves in the ion cyclotron range of frequencies (ICRF) ...

Design and higher order optimisation of final focus systems for linear colliders

Marín Lacoma, Eduardo (Date of defense: 2012-12-21)

The accelerator and particle physics communities are considering a lepton Linear Collider LC as the most appropriate machine to carry out high precision particle physics research in the TeV energy regime. The Compact Linear ...

Evaluation of TH multi-scale coupling methods in BEPU analysis

Casamor Vidal, Max (Date of defense: 2022-10-11)

The combined use of thermal-hydraulics system with sub-channel codes (TH-TH coupling) in transient analysis provides an integrated tool with the capability of modelling in detail both the core thermal-hydraulic conditions ...

First measurement of beta-decay half-lives and neutron emission probabilities in several isotopes beyond N = 126

Caballero Folch, Roger (Date of defense: 2015-06-05)

In this work beta-decay half-lives and neutron-emission probability values have been experimentally determined for first time in several nuclei beyond the neutron-shell closure at N=126. To this aim the accelerator complex ...

Local optics corrections in the HL-LHC

Coello de Portugal - Martínez Vázquez, Jaime Maria (Date of defense: 2021-06-16)

In order to increase the performance of particle colliders, it is crucial to make the beam sizes at the collision points as small as possible. This causes an increase of the beam size in the region surrounding the collision ...

Neutron capture cross section measurement of the heaviest s-process branching 204Tl and of 203Tl at CERN n_TOF

Casanovas Hoste, Adrià (Date of defense: 2020-10-27)

Neutron capture cross sections are fundamental in the study of the slow neutron capture process of nucleosynthesis, also known as the s-process, which produces half of the observed solar system abundances of elements heavier ...

Predictive simulation, active diagnosis and dynamic monitoring for tritium processing systems

Iraola de Acevedo, Eduardo (Date of defense: 2024-07-01)

(English) Nuclear fusion has been under development for years, showing consistent advancements toward becoming a clean and efficient energy source. However, significant challenges persist in this field, with tritium handling ...

PyMCGPU-IR, a computational Monte Carlo application for occupational dosimetry in interventional radiology procedures

García Balcaza, Víctor (Date of defense: 2024-09-18)

(English) Interventional radiology procedures expose both patients and operators to radiation. It is crucial to minimise this exposure and comply with dose limits while ensuring the success of the procedure. Personal ...
