Contribution to the validation of best estimate plus uncertainties coupled codes for the analysis of NK-TH nuclear transients
The calculations that allow the operating license of the nuclear reactors are usually made using conservative methods. This conservatism, often excessive, limits the actual capabilities of the industry to increase energy ...
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 ...
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 ...
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 ...
Design of a 4 π neutron detector for ß-delay neutron detection experiments.
Beta delayed neutron emission probability is one of the main properties of neutron rich nuclei away from the valley of beta stability. The knowledge of this parameter provides the opportunity to extend the information on: ...
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 ...
Optimization of alpha emitter's determination in water. Behavior of radionuclides in water treatment plants
La determinació de l’índex alfa total en aigües és d’interès per ser un dels paràmetres inclòs en la legislació nacional e internacional associada a la qualitat de l’aigua per al consum humà. Aquest índex informa de la ...
Design and characterization of magnetic systems in race-track microtrons
During last four or five decades there has been a growing demand in particle accelerators which can provide electron beams in the energy ranging from 2 MeV to 100 MeV with high energy resolution and good dose control. Other ...
Impacte dels canvis anatòmics sobre la distribució de dosi en els pacients amb càncer de cap i coll tractats amb 3DCRT i IMRT
En aquesta tesi s’estudien les implicacions dosimètriques que comporten els canvis anatòmics que pateixen els pacients afectats de càncer de cap i coll (CCC) durant el tractament de radioteràpia (RT). L’estudi es realitza ...
Contribución a la caracterización de aerosoles radiactivos derivados del radón
La existencia de una relación entre el riesgo a desarrollar un cáncer de pulmón y la exposición al radón y descendientes presentes en el aire se puso de manifiesto hace ya bastante tiempo en la población minera. Desde ...
