摘要： A system for high speed acquisition and storage of data from transient electrical signal waveforms sampled in time at a multiplicity of points, and where it is desired to collect and store data in real time in a mass storage unit, but where the data rate is in excess of the apparent rate at which data can be transferred to mass storage. The overall system employs two levels of data reduction, the first being digital integration (summation) and the second being data processing. In the digital summation section memory read and write cycles overlap for higher speed. In one embodiment, a charge-coupled device is employed as an input element to reduce the data rate prior to subsequent digital processing. The system is capable of recording all the intensities of all transients continuously without loss of data significance.

摘要： A method and a system for calibrating an X-ray photoelectron spectroscopy (XPS) measurement are described. The method includes using an X-ray beam to generate an XPS signal from a sample and normalizing the XPS signal with a measured or estimated flux of the X-ray beam. The system includes an X-ray source for generating an X-ray beam and a sample holder for positioning a sample in a pathway of the X-ray beam. A detector is included for collecting an XPS signal generated by bombarding the sample with the X-ray beam. Also included are a flux detector for determining a measured or estimated flux of the X-ray beam and a computing system for normalizing the XPS signal with the measured or estimated flux of the X-ray beam.

摘要： A position sensitive detector and method are disclosed wherein an image of incident radiation is detected and amplified and an accelerated charged image is produced corresponding spatially to the incident radiation. The accelerated charged image is successively impinged on successive pairs of interdigitated electrodes having different electrode patterns and the output of the electrodes is compared for determining the location of the charges making up the charged image.
