“…The neutron spectra are generated through unfolding (de-convolution) process of these eight measurements using STAY'SL (Perey, 1977) and MAXED (MAXimum Entropy Deconvolution) (Reginatto and Goldhagen, 1999;Reginatto et al, 2002) FORTRAN coded algorithms. Both unfolding codes require a very sensible a priori (guess) spectrum (Alevra, 1999;Alevra and Thomas, 2003). The STAY'SL unfolding features, such as generation of uncertainties of the response functions and guess spectra, as well as covariance matrix (corresponding to response function matrix), are discussed in detail in our earlier paper on neutron metrology and dosimetry in research nuclear reactors (Atanackovic et al, 2013).…”
