Abstract
A radiation detection device comprises a radiation source and a plurality of detectors and crystals positioned thereabout to simultaneously detect certain known wavelengths. Each detector emits a signal representative of the intensity of the detected wavelength and a summing means adds the signal intensities together to give a unitary output signal. This summed output signal can then be used as a material sorter through a direct read out or can go into a function circuit which compensates an X-ray thickness gauge for changes in composition. In the latter situation, a function circuit output can be fed forward to control the machinery responsible for producing the thickness obtained.

A radiation detection device comprising:
- A. a radiation source for emitting radiation particles onto a sample;
- B. a plurality of crystals, each positioned about the radiation source to simultaneously receive reflected radiation particles from the sample and reflect a given wavelength from an elemental constituent of the sample;
- C. a plurality of radiation detectors, each positioned with respect to a crystal to simultaneously detect the given wavelength;
- D. summing means for receiving signals representative of each of said detected wavelengths from said detectors and for summing said signals into an output signal;
- and
- E. identifying means for receiving said output signal from the summing means and utilizing said summed signal to identify a compositional characteristic of the sample.
A process for identifying a compositional characteristic of a sample comprising:
- A. subjecting the sample to a radiation detecting device comprising a radiation source, a plurality of crystals each set to reflect a given wavelength of an elemental constituent of the sample and a plurality of detectors, each positioned with respect to a crystal to detect the given wavelength;
- B. bombarding the sample with radiation particles;
- C. simultaneously reflecting the particles off each of the crystals;
- D. simultaneously counting the reflected particles in each of the detectors;
- E. simultaneously transforming the counted particles into an output signal;
- F. simultaneously transmitting the output signal to a summing means;
- G. summing the individual output signals into a single output signal characteristic of the composition of the sample;
- and
- H. utilizing the single output signal to identify the sample.
