Full textNo presente trabalho o método de Rayleigh-Ritz é utilizado na determinação dos campos modais e dos números de onda de corte em guias de onda de seção arbitrária. Inicialmente, o método é aplicado com funções de base polinomiais, sendo a seção transversal do guia aproximada por um polígono convexo. Este tipo de função limitou o número de modos que podem ser calculados, uma vez que polinômios de grau alto geram instabilidades computacionais e overflow. Utilizando a mesma metodologia, os campos modais em guias de onda superquadráticos são analisados. Entretanto, as funções de base polinomiais são substituídas por funções trigonométricas, produzindo um modelo numérico capaz de computar um grande número de modos em um tempo de execução razoável. Os guias superquadráticos constituem uma classe de guias uniformes, incluindo guias circulares, elípticos, quase retangulares e outros de seções intermediárias. Conseqüentemente, eles são úteis na construção de diversos dispositivos em guias de onda, incluindo transições de diferentes seções, tais como circular para elíptica e circular para retangular. O método do casamento de modos é aplicado na determinação da matriz de espalhamento de descontinuidades entre guias superquadráticos. Diversas aplicações numéricas são apresentadas e comparadas com resultados obtidos através de outras técnicas.
In the present work, the modal fields and cutoff wavenumbers of arbitrary cross section waveguides are determined using the Rayleigh-Ritz method. Initially, the method is applied to waveguides with cross section approximated by a convex polygon. Polynomial basis functions are used. Such basis functions limit the number of modes that can be computed, since polynomials of high degree generate computer instabilities and overflow. Using the same methodology, the modal fields of superquadric waveguides are analyzed. Polynomial basis functions are replaced by trigonometric functions, however, producing an efficient numerical model capable of computing a large number of modes with a reasonable computer time. Superquadric waveguides constitute a class of uniform waveguides that include circular, elliptical, almost rectangular waveguides and a series of intermediate cross section waveguides. As a consequence they are quite useful in the construction of several devices, including transitions between waveguides of different cross sections, such as circular to elliptical and circular to rectangular. The mode matching technique is applied to the determination of the scattering matrix of discontinuities between superquadric waveguides. Several numerical applications are presented and compared to results obtained from other techniques.

Full textUn anàlisi de sensitivitat [1] recent per la nova generació de reactors ràpids va mostrar la importància de millorar les seccions eficaç de varis actínids. Entre ells, la secció eficaç de fissió per neutró induït del 240,242Pu requereix una millora en la seva precisió des d'un 6% a un 1-3% pel 240Pu i des d'un 20% a un 3-5% pel 242Pu. A més, quasi bé totes les dades experimentals disponibles a la literatura han estat determinades relatives a la secció eficaç del 235U(n,f). Per tant, la utilització d'altres isòtops com a referències, tal com el 237Np(n,f) o el 238U(n,f), proveirà a la comunitat científica amb dades valuoses. Aquest treball ha estat realitzat a l'Institute for Reference Materials and Measurements (JRC-IRMM). L'accelerador Van de Graaff disponible al JRC-IRMM s'ha emprat per produir un flux de neutrons quasi mono-energètics en el rang de 0.3 MeV a 3 MeV. Els protons van ser accelerats de fer-los impactar amb una mostra de producció de neutrons: 7Li(p,n)7Be o T(p,n)3He. A continuació, una doble cambra d'ionització amb grid (TFGIC) es va emplaçar com a detector consistent en un càtode, dos ànodes i dos grids. En el càtode es situen la mostra a estudiar i la mostra de referència. Cada un dels elèctrodes és connectat a un preamplificador i, a continuació, a un digitilitzador amb una freqüència de 100 MHz i 12 bit. Les senyals originals són emmagatzemades sense cap tractament previ per a un posterior anàlisi. El tractament de dades es va realitzar mitjançant el codi de programació C++ sota el marc de ROOT. Totes les mostres emprades en aquest experiment s'han produït al grup de preparació de mostres del JRC-IRMM. L'enriquiment de les mostres de plutoni era de 99.89% pel 240Pu (0.8MBq) i del 99.97% pel 242Pu (0.1MBq). La massa de les tres mostres de referència (235U(n,f), 238U(n,f) i 237Np(n,f)) també va ser mesurada. La incertesa de cada massa és inferior al 2%. La principal correcció aplicaca als resultats obtinguts ha estat per la caracterització del flux de neutrons mitjançant el codi de simulació Monte Carlo MCNP. Els resultats de les simulacions han mostrat una clara influència de les diferents estructures emplaçades entre la mostra de producció de neutrons i les mostres de fissió. Altres correccions s¿han realitzat per la fissió espontània del 240,242Pu (mesurada independentment en aquest treball amb una incertesa inferior al 1,3%), la deficiència d'esdeveniments a causa del llindar de detecció, l'eficiència del detector, l'anisotropia en l'emissió dels neutrons, etc. Tot i que el principal objectiu va ser l'obtenció de la secció eficaç de fissió per neutró induït del 240,242Pu en la regió de 0.3 MeV a 3 MeV, resultats addicionals han estat obtinguts per la secció eficaç del 238U(n,f) i el 237Np(n,f). Els resultats obtinguts mostren un acord significatiu entre la secció eficaç del 240,242Pu(n,f) i resultats experimentals anteriors, tot i que la tendència és lleugerament inferior a les avaluacions (ENDF/B-VII.1, JEFF 3.1 i JENDL 4.0) disponibles. En el cas de la secció eficaç del 242Pu(n,f), a més, el pic de ressonància al voltant de 1.1 MeV predit per quasi totes les dades experimentals anteriors i les avaluacions actuals no s'ha reproduït en aquest experiment. Els resultats de la secció eficaç del 237Np(n,f) presenten un increment en la regió plana després del llindar de fissió d'un 5-7% respecte l'avaluació ENDF/B-VII.1, i en concordança amb els resultats obtinguts per Paradela (2010) [2]. Finalment, els resultats de la secció eficaç del 238U(n,f) mostren un increment al voltant d'un 7-9% a la zona plana després del llindar de fissió, aquesta predicció concorda amb l'avaluació JEFF 3.2.

Full textThis thesis presents MCNPX simulations of the SCANDAL set-up used at the Theodor Svedberg Laboratory for neutron scattering cross-section measurements. The thesis describes processes and data important for the upcoming off-line data analysis. In the experiment, neutrons scattered off the target are converted to protons which are stopped in scintillator crystals. The results of presented simulations include a description of the proton spectra in dependence of the neutron-to-proton conversion angle, calculation of the hit position gates and a study of the converter describing the role of its chemical composition and also the role of other plastic scintillator on the proton spectra.
