Projeto e construção de monocromadores de elétrons para experimentos de captura eletrônica dissociativa em moléculas de interesse biológico.

Abstract

When we study low energy electrons (LEE) and the interaction with molecules, a series of different types of applications arise, from the development of equipment for the plasma industry, to the development of new radiotherapeutic drugs, to studies of organic molecules with biomedical and exobiological interests. . In order for us to study these different processes, a series of equipment is essential, as they will allow us to simulate phenomena that are often natural in fully controlled environments. Some equipment that can be highlighted are particle monochromators (TEM and HEM) and mass spectrometers (reflectron and quadrupole). With this work we aimed to understand the entire investigation process from the choice of design of some devices, modeling and simulation, construction, operation and data analysis. For this, two equipment configurations were studied, the TEM-ToF (at Universidade NOVA de Lisboa) and Wippi (at the University of Innsbruck), giving greater attention to the monochromators used there, since the aim was to absorb all the processes highlighted previously, obtain the better results, measurements and analyzes and with that to complete the construction of the atomic collision line in the CACIS laboratory at UFJF.
