Concerning nuclear data, our SCALP project aims to measure the differential energy cross section of (n,alpha) reactions on 16O and 19F. These measurements are of interest for reactors. Experiments with the SCALP device will take place at NELBE (at HZDR, Dresden, Germany), at GELINA (at JRC-IRMM, Geel, Belgium) and at NFS (at SPIRAL2, Caen, France). This project is partly funded by European projects.
