| Research Abstract |
Two fission fragments, generated simultaneously at the spontaneous fission phenomena of Cf-252, were utilized - one for SEU measurements for Devices and another for fission fagments energy detection by Si SSDs. And the mass and effective charge of the fragment got into Devices was identified. For the identification the following relations were used :
in the Cf fission
E_2/E_1=M_1/M_2 : E_1+E_2=186 MeV : M_1+M_2=248 AMU (mass difference 4 is attributed to prompt neutron emission)
Cf-252 source was mounted on 0.1mum Ni foil. So that both fission fragments can be utilized without actual energy loss passing through the supporting Ni foil.
