Contributions to new challenges in radiotherapy : from small field dosimetry to stereotactic body radiation therapy
The use of small Fields has substantially increased in radiotherapy during recent years mainly due to expansion in the use of modulated techniques which are also used at some institutions for Stereotactic Body Radiotherapy ...
Quantification of dopaminergic neurotransmission SPECT studies with 123 l-labelled radioligands
Dopaminergic neurotransmission SPECT studies with 123I-labelled radioligands can help in the diagnosis of neurological and psychiatric disorders such as Parkinson¿s disease and schizophrenia. Nowadays, interpretation of ...
Development of AINA code for the study of loss of plasma control events in ITER and DEMO, and contribution to the systems study of DEMO
Magnetic fusion is a long term, worldwide research activity. Plans are increasingly ambitious, cooperation is progressing, and goals seem to be closer every year. ITER reactor is being built, and several conceptual studies ...
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 ...
Scaling-up methodology : a systematical procedure for qualifying NPP nodalizations. Application to the OECD/NEA ROSA-2 and PKL-2 Counterpart test
System codes along with necessary nodalizations are valuable tools for thermal hydraulic safety analysis. Qualifying both codes and nodalizations is an essential step prior to their use in any significant study involving ...
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: ...
Development of a simulation tool for MHD flows under nuclear fusion conditions
In Nuclear Fusion Technology, MHD flows can be encountered in liquid metal (LM) breeding blankets, the part of a fusion reactor where tritium, one of the fusion fuels, is to be produced. There are several types of LM ...
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 ...
Caracterización de aerosoles radiactivos en la ciudad de Barcelona
This research work has been developed in order to contribute to the knowledge of radioactive aerosol characteristics and their behaviour in the atmosphere. The study was carried out in the city of Barcelona. The Instituto ...
New developments on preparation of cooled and bunched radioactive ion beams at ISOL-Facilities: the ISCOOL project and the rotating wall cooling
Last years have become very productive for the research, construction and development of new facilities devoted to the production of beams with exotic radioisotopes (Radioactive Ion Beams, RIB). These beams are later used ...
Development of advanced geometric models and acceleration techniques for Monte Carlo simulation in Medical Physics
Els programes de simulació Monte Carlo de caràcter general s'utilitzen actualment en una gran varietat d'aplicacions.<br/>Tot i això, els models geomètrics implementats en la majoria de programes imposen certes limitacions ...
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 ...
Study of electron heat transport in LHD and TJ-II
The magnetically confined plasmas study is one of the most promising research fields in the present days due to the high perspectives of unlimited and clean energy that fusion has generated. In this framework, the stellarator ...
Assessment of size aspects in modelling molten fuel coolant interaction.
Severe accidents in light water nuclear reactors occur when reactor vessel water inventory decreases and there is no available additional water coolant to be delivered into the core. In general, during an extended severe ...
Cryogenic Silicon Microstrip detector modules for LHC
CERN is presently constructing the LHC, which will produce collisions of 7 TeV protons in 4 interaction points at a design luminosity of 1034 cm-2 s-1. The radiation dose resulting from the operation at high luminosity ...
Aportaciones al estudio de los campos de radiación ionizante ambiental
Amb aquesta tesi s'intenta aportar la informació necessària per a millorar el coneixement dels camps de radiació ionitzant ambiental d'origen natural, i contribuir així a la millora de la gestió de les estacions de vigilància ...
Absolute quantification in brain SPECT imaging
Certes malalties neurològiques estan associades amb problemes en els sistemes de neurotransmissió. Una aproximació a l'estudi d'aquests sistemes és la tomografia d'emissió SPECT (Single Photon Emission Computed Tomography) ...
Estudio del transporte de energía en plasma de fusión termonuclear con medidas experimentales obtenidas del espectrometro de intercambio de carga, realizado mediante técnicas de participación remota.
En la investigació de la fusió termonuclear controlada per confinament magnètic es important conèixer el transport d'energia en els plasmes, doncs aquest transport és el que fa que es refredi més o menys ràpidament amb el ...
Radiation Transport Modelling in a Tokomak Plasma: Application to Performance Prediciton and Design of Future Machines
The understanding and modelling of heat and radiation transport in tokamak plasmas is essential in order to progress in the development of thermonuclear fusion towards a practical energy source which meets all the future ...
