Bremsstrahlung de elétrons no microtron do IFUSP: medidas, simulação e proposta de aplicação ao estudo da ressonância fluorescente nuclear

Abstract: The results of the first experiments carried out in the new electron accelerator of the Linear Accelerator Laboratory (LAL) of the Physics Institute of Universidade de São Paulo are reported here. A 1.9 MeV beam line, which allows the use of the injector beam for experimental physics, was added to the original accelerator design. Electron bremsstrahlung spectra for Ag and Au thin targets observed at 30 o and 60 o with respect to the beam direction were collected in a HPGe coaxial detector, whose dimensions, in… Show more

“…The vacuum chamber is made of stainless steel and its internal wall is lined with Al foil near the beam exit flange, which was framed with C to minimize unwanted electron bremsstrahlung. The beam was caught by a Faraday cup made of graphite, designed to reduce electron backscattering [36]. It was surrounded by Pb bricks (outside the vacuum chamber) to reduce the radiation background.…”

“…Este estágio do acelerador já se encontra em funcionamento e medidas realizadas com o feixe após a segunda estrutura, determinaram uma energia de 1,909(5) MeV [4] Tendo em vista que o feixe atualmente produzido pelo linac injetoré su-ficientemente estável para realização de alguns experimentos, foi construída uma derivação na entrada do Mícrotron booster. A nova linha já está sendo usada para determinação da seção de choque de ionização da camada K, estudos sobre a seção de choque de produção de bremsstrahlung [6] e caracterizações do feixe utilizando ROT (RadiaçãoÓptica de Transição) [7].…”
