Sirius is one of the first fourth-generation synchrotron light sources, currently in operation by the Brazilian Synchrotron Light Laboratory — Fig. 1.

One of the subsystems composing the synchrotron light source is the vacuum chamber system, defining the environment in which the electron beam travels under the influence of electromagnetic fields. This environment should have a small quantity of molecules because collisions between the electron beam and gas molecules can lead to loss of stored electrons and a ..
