GSI activities for SAFERIB in 2005

G. Fehrenbacher, F. Gutermuth, E. Kozlova, T. Radon (GSI, department for safety and radiation protection)

Status •Progress in Monte Carlo Code •Measurements of double differential neutron yields •Calculation and measurements of activated targets Planned activities •Calculation and measurements of activated components SAFERIB Saclay

27.10.05

Progress in MC-calculations with FLUKA

• usage of the heavy ion version of FLUKA •development of a routine for scoring (the fluence of) projectile fragments

•usage of the remanent dose feature of FLUKA 2005 (since august 05) •Comparisons of remanent dose with tabulated activity-to-dose-rate factors for easy geometry •remanent dose calculation for a shielding wall at the existing Fragment Separator (E. Kozlova)
