The Fusion Neutronics Source (FNS) of JAERI currently carries out the measurements of energetic charged particles emitted from fusion materials irradiated with a well-collimated 14 MeV neutron beam. At the beginning, the double differential cross section beryllium was measured. We have measured proton, triton and a particle emitted from a beryllium sample of 100 m in thickness.The a particle and triton were produced by Be(n,)He, Be(n,2n)2 and Be(n,t)Li reactions respectively. Measured total reaction rates from the counts of a particles and tritons were 2.710 and 610/atom/neutron, respectively, which were consistent with the calculated values from the nuclear data JENDL-3.2.
