Measurement of Fragment Production Cross-section on Nucleon-induced Reaction

摘要

We introduce our activities on measurements of fragment which are secondary particles heavier than alpha-particles produced by nucleon-induced reaction and have been recognized to be a cause of serious problem to semiconductor devices and human in a space environment by using a Bragg curve spectrometer (BCS) and energy-time-of-flight method (E-TOF), together with the activities in other facilities. For these studies and estimation, it is important to know the fragment production yield including the energy and angular distribution (double-differential cross-section (DDX) data) of fragments emission.rnWe have resulted in success to obtain light fragments on proton- and neutron-induced reactions by using a BCS developed for neutron specially and E-TOF method. Double-differential fragment production cross-sections obtained will be applied for the analysis of SEU and dose contributions.
