Arrangement for measuring radiation quanta and spectrometer provided with such an arrangement.

摘要

In a spectrometer (1), a preparation (4) is irradiated with X-ray radiation. X-ray quanta emitted by the preparation (4) are converted after reflection by an analysis crystal (9) by a detection device (13) into pulse signals. In a pulse discrimination device (26), the pulse signals are discriminated and are recorded as single or multiple integrated pulse signals in a signal processing device (40) as numbers of pulse signals. After termination of the measurement, the numbers of pulse signalsare read out from the signal processing device (40) and an analysis on the numbers takes place by means of a data processing device (51). For example, the total number of detected quanta of monochromatic radiation may be determined.
