X-ray Optical System
|
| The R-AXIS IIC x-ray optical system, schematically
shown here, is contained in what known as a mirror box. The position
and curveture of the two mirrors in the system can be adjusted manually
using the mirror optics controls together with a PDA-18 meter (shown
below), which converts x-ray intensity to current This component of
the R-AXIS determines how good one can focus the x-ray beam from the
generator. |

| This is a figure of the main device for x-ray beam
alignment. The optics control can operate on the mirrors in terms
of translating and focusing, as well as closing and opening the slit
associated with a particular mirror. The only purpose of these manipulations
is to obtain the highest possible monochromatic x-ray beam intensity
while cutting as much as possible the white x-ray (refer to standard
text books for x-ray optics). This task can only be accomplished when
some sort x-ray detectors, in this case a PDA-18 meter, is used. Get
yourself familiarized with the knobs and switches on the control box,
refer to the figure above if necessary to understand how these controls
work. Go to beam alignment for details. |
