In quantitative ion beam analysis the intensity of the detected signal depends on many factors including the amount of element in the sample, the probability of inducing a signal, the efficiency of the detection system and the number of ions impinging on the sample. Calibration of an ion beam experiment can be performed in either of two ways: using literature data for the physical constants involved and calculated detector characteristics; using calibration standards of the respective element of known thickness. In order to verify the absence or magnitude of systematic errors, in any of the calibration parameters, a standard or reference material is employed which is produced according to the international measurement system, the SI.
