Abstract: An X-ray analyzer comprises at least one detector configured to detect a secondary X-ray from a test object irradiated by an X-ray source, and provide a corresponding energy signal; a temperature sensor configured to sense a temperature related to the detector; and a signal processor configured to process the energy signal and provide a temperature compensated output for an X-ray event.

Abstract: Disclosed are circuits for automatic calibration of the gain of electronic amplification and digitization systems for use with X-ray detectors. The calibration is based on injecting predetermined pulses into the electronic system and deriving a calibration ratio based the digital value of their amplitude with the digital value of the same pulses, unamplified and digitized with a high accuracy reference ADC. All ADCs, as well as the DACs used to control the pulser amplitude are referenced to a single common reference voltage. Calibration for non-linearity of the gain is disclosed with an alternative embodiment for the same circuits.

Abstract: A compact, low cost device for laser induced breakdown spectroscopy (LIBS) makes use of a silicon photomultiplier detector and a photon counting method.

Abstract: Herein disclosed is an x-ray florescence (XRF) test system which comprises an XRF test instrument used for testing a test target's responses to X-rays, the instrument including a test window allowing the X-ray and its responsive energy to pass through, and a window protecting film assembly allowing X-rays to pass through and providing protection to the window, the film assembly being configured to be coupled with the window in a fashion to be removed from or applied or reapplied over the window. The corresponding calibration mode can be manually or automatically applied according to the specific film assembly presently in use. An embodiment of the film assembly comprises a thin film fixed with an adhesive layer to a supporting frame having a closely spaced array of apertures.

Abstract: The present invention relates to a separator including one or more separation members upon which residue can accumulate. An agitator is provided for agitating the separation members to remove the residue. The agitator may clean residue from the members without removing the separation members from the separator. Advantageously, the frequency that the members need to be removed from the separator and thoroughly cleaned is reduced when compared with the known separator.
