Description
Image
A radiation collimator for use in either radiation-emitting
devices (e.g., radiation therapy) or radiation-sensing imagery
devices (i.e., gamma/X-ray cameras) is disclosed. The
collimator's interior surface is basically a cylinder or a truncated
cone, whereas its exterior shape is generated by the
revolution of the graph of a function about the cylinder's
symmetry axis, that function being determined such that the
attenuation in the center of the sensor is constant as seen from
any direction. The collimator is a body of revolution. The said
collimator improves collimation and image resolution when
compared to cylindrical, pinhole, laminar, or
to other art collimators.
Applications: Radiation detectors, Environment monitoring,
medical equipment (X ray, gamma camera, gamma knife).

The invention consists of an electronic device that is capable to
generate radiofrequency signal (13.56MHz) and to maintain
plasma (~100W) at atmospheric pressure. It is used to generate
integrated plasma in spectral analysis systems to estimate

chemical composition of earth probe, materials, waste products,
etc. The device is portable, more reduced in weight and size,
and has a very high power coupling efficiency. So it is a very
useful tool for "in situ" chemical analysis of soils.
