Optimization of field matching in external photon beam radiation therapy
Radiation therapy is one of the main modalities used for treating cancer patients, together with surgery and chemotherapy. Radiotherapy treatments can be carried out with a great variety of devices, but most treatments are ...
Hydrogen production from bioethanol using cobalt hydrotalcites
Hydrogen constitutes a promising alternative to manage our energy supply more efficiently. Hydrogen can be stored and used in fuel cells to produce electricity, where it combines with the oxygen present in the air and ...
IFMIF accelerator facility RAMI analyses in the engineering design phase
The planned International Fusion Materials Irradiation Facility (IFMIF) has the mission to test and qualify materials for future fusion reactors. IFMIF will employ the deuteron-lithium stripping reaction to irradiate the ...
Neutron-induced fission cross section of 240,242Pu
A recent sensitivity analysis done for the new generation of fast reactors [1] has shown the importance of improved cross section data for several actinides. Among them, the neutron-induced fission cross section of 240,242Pu ...
Comparative study of Final Focus Systems for CLIC and other luminosity enhancement studies for future linear colliders
The 4th of July 2012 was a milestone date in the history of physics of the last decades. The discovery of the Higgs boson at the ATLAS and CMS experiments thanks to the proton collisions delivered by the LHC not only has ...
Catalytic hydrogen production over RhPd/CeO2 catalysts and CO purification over Au/TiO2 catalysts
This Thesis focuses on the study of the catalytic production of hydrogen from a biofuel, namely the bioethanol. It also studies the subsequent purification of pre-cleaned reformate streams. The end use of the hydrogen ...
First measurement of beta-decay half-lives and neutron emission probabilities in several isotopes beyond N = 126
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 ...
Automation of the Monte Carlo simulation of medical linear accelerators
The main result of this thesis is a software system, called PRIMO, which simulates clinical linear accelerators and the subsequent dose distributions using the Monte Carlo method. PRIMO has the following features: (i) it ...
Design of the BELEN detector for wide energy range with flat and high detection efficiency
