Application of Calorimetric Low Temperature Detectors for investigation of Z-distributions of fission fragments
In recent experiments (2014/2015), use of the novel technology of Calorimetric Low Temperature Detectors (CLTD) proved to be very successful for the investigation of nuclear charge distributions of fission fragments at LOHENGRIN. Applying the well-known passive-absorber method with recently available homogenous silicon-nitride (Si3N4) absorber foils in combination with CLTD residual-energy detectors, shows promising Z-yield resolution. Employing several improvements to the current set-up, we intend to push the measurements from light fragments to symmetry and the light side of the heavy fragment group. Measurements near symmetry give the opportunity to study the even-odd staggering of charge yields which is a sensitive test of fission models. Also, the perspective of reaching Z-yield determination in heavy-fragment group this way, would provide an alternative and complementary method to gamma spectroscopy and radio-chemistry.
