  • Title: Concept for an off-line gain stabilisation method.
    Author: Pommé S, Sibbens G.
    Journal: Appl Radiat Isot; 2004; 60(2-4):151-4. PubMed ID: 14987634.
    Abstract:
    Conceptual ideas are presented for an off-line gain stabilisation method for spectrometry, in particular for alpha-particle spectrometry at low count rate. The method involves list mode storage of individual energy and time stamp data pairs. The 'Stieltjes integral' of measured spectra with respect to a reference spectrum is proposed as an indicator for gain instability. 'Exponentially moving averages' of the latter show the gain shift as a function of time. With this information, the data are relocated stochastically on a point-by-point basis.
