For the nuclear charge identification 2378000100021 the passive absorber method with a novel detector 2378000100022 technology of calorimetric low temperature detectors 2378000100023 CLTDs measuring the residual energy after passage 2378000100024 through SiN absorber foils is applied. 2378000100025 METHOD (ASEP) 2378000100026 (EDEG) 4 um thick SiN degrader foil stack 2378000100027 ANALYSIS (UNFLD) The residual energy spectra of mass and energy 2378000100028 separated fragments from the LOHENGRIN spectrometer 2378000100029 are fitted with a sum of Gaussians to determine the 2378000100030
