1. Analysis and PIC simulation of a Gyrotron travelling wave tube amplifier
The analysis of a Ka-band gyrotron Travelling Wave Tube (gyro-TWT) amplifier using a uniform cylindrical waveguide as its interaction circuit has been presented for the TE01 mode of operation a self-consistent nonlinear analysis in the large signal regime. The analysis predicts that the saturated peak output power of ~ 134 kW with a power conversion efficien

2. Low-energy levels calculation for 193Ir
In this work, a model based on single particle plus pairing residual interaction was used to study the low-lying excited states of the 193Ir nucleus. In this model, the deformation parameters in equilibrium were obtained by minimizing the total energy calculated by the Strutinsky prescription; the macroscopic contribution to the potential was taken from the

3. A influência dos parâmetros do vento solar na emissão de AKR durante tempestades magnéticas / The influence of the solar wind parameters on the AKR emission during magnetic storms
Several phenomena could be better studied and even disclosed after the development of the satellites and spacecrafts. Auroral Kilometric Radiation (AKR) is one of these phenomena. AKR was first detected only about thirty years ago; its typical frequencies are too low to penetrate earthward across the ionosphere. This radiation is generated through wave-parti

4. \ 58 ANTPOT. Co\ : estudo de um núcleo ímpar-ímpar na camada pf / 58Co: study of an odd-odd nucleus in the pf shell
The excited states in the doubly odd nucleus \ ANTPOT. 58 CO\ have been studied using inbeam gama-ray spectroscopy. The \ ANTPOT. 58 CO\ nucleus has been produced with the fusionevaporation reaction \ ANTPOT. 51 V\ (ANTPOT. 10 B\ , p2n) at 33 MeV bombarding energy, using the SMV Pelletron accelerator of the University of São Paulo.

5. Simulação Híbrida para choques em plasmas espaciais / Hybrid simulation applied to shock waves in space plasmas
dissertação de mestrado são estudados três problemas fundamentais da Física Espacial, a saber: a instabilidade eletromagnética íon-íon ressonante (IEIIR), uma onda de choque quase-perpendicular supercrítica e a interação entre um feixe de íons de extensão finita com um feixe de íons de fundo. Um código híbrido eletromagnético e unidimensiona

7. Numerical analysis of weakly nonlinear wave turbulence
We consider the propagation of weakly nonlinear waves such as plasma waves, surface water waves, the interaction of laser beams with matter, particle accelerators, etc. Specifically, we study internal waves in the ocean. Hamilton's principle is used to write the fluid equations in Hamiltonian form in terms of linear eigenmode amplitudes. Numerical studies ar
