Presentation of the CALMAR-ECORCES spectrum ajustment package available at the NEA Data bank

Abstract : Adjustment methods are well known for the determination of a multigroup spectrum from foils activity measurements and have been included for many years in ASTM standards. These inversion methods combine information from activity measurements of foils with their respective response functions (cross sections and covariances) to provide a best-estimate multigroup spectrum. According to the selected method, one should provide an optional prior spectrum as input. An adjustment library CALMAR has been developed and some aspects of the library has already been exposed, this paper focusses on the public release of the library. Then it describes examples of use of the ECORCES code for nuclear data preparation and CALMAR code for the adjustment procedure.
