Automatic calibration of multi-strip position-sensitive detector

Calibration is the transformation of the output channels of a measuring device into the physical values (energies, times, angles etc.) If dealt with manually, it is a labor- and time-consuming procedure even if only few detectors are used. However, the situation worsens appreciably if the calibration of multi-detector systems is required, where the number of registering devices extends to hundreds [1]. The calibration is aggravated by the fact that needed pivotal channel numbers should be determined from peak-like distributions. But peak distribution is an informal pattern so that a procedure of image recognition should be employed to discard the operator interference. The report discusses an algorithm for an automatic calibration and describes instances of its verification with use of both simulated data and real alpha spectra.
