Features of spectral-angular distribution of coherent X-radiation

Abstract: The properties of coherent X-radiation CXR, generated in crystals by electrons in the tens of MeV energy range, were investigated theoretically. The analytical expressions for CXR spectralangular and angular cross sections were obtained with the use of small-angle multiple scattering approximation. Our theoretical results are in good agreement with experiment. The obtained results can be used in designing quasi-monochromatic, tunable and polarized X-radiation sources based on the CXR process.

“…Figures 3a and 3b show the radiation spectra resulting from the interaction of 20 MeV electrons with the liquid crystal, which has a z = 8Å, r = 19Å, and α = 24 0 . The CXR intensity achieves its maximum values at ϕ = θ γ /2 ± 1/2γ ( [5]) and for Figs. 3a and 3b we took θ γ = 45 0 and ϕ = 21.8 0 .…”

“…No contexto de feixes empacotados, como no caso de feixes produzidos em aceleradores lineares e mícrotrons, a distribuição longitudinal pode ser representada como uma gaussiana de desvio padrão σ t , que basicamenteé o comprimento quadrático médio do pacote de partículas do feixe em unidade de tempo 6 .…”

“…Este tipo de experiênciaé interessante de ser realizada em física nuclear por fornecer resultados de maior qualidade. Já o acelerador Mícrotron, por ter fator de utilização mais alto, possibilitará um salto qualitativo nas experiências a serem realizadas no LAL, em física nuclear básica com experiências de coincidência em linha [4,5], em física da matéria condensada [6], em física atômica, física médica e das radiações. As principais características do projeto do novo acelerador são resumidas na tabela 1.1.…”
