A
brief review of the story and appearance of capillaries and polycapillaries is
presented. The most important applications and implementations of polycapillaries
are described and the generalities of the manufacturing process are explained.
Polycapillaries
made in the local laboratory are shown. The manufacturing procedure is
described along with the different apparatus used during the process.
Several
polycapillaries with different characteristics were studied and characterized
in local lab using a conventional x-ray source and in the LNLS (Campinas,
Brzil) using synchrotron radiation. These results are summarized.
Some
applications of selected polycapillaries are described and the most important
results are presented. A very interesting application, such as dispersive
diffraction in combination with XRF, is described in detail and some
interesting results are shown.
