【Abstract】 High resolution powder neutron diffractometer is one of the neutron scattering instruments in the first installation phase. Nuclear electronics system which is used for neutron signal acquisition and signal processing is the key instrument of this diffractometer. The aging and maintenance for nuclear electronics system using input signal is the key part for installation and debugging of this nuclear electronics system. The function of aging and maintenance experiments using input signal is introduced. The design and implementation is described in detail. The problems which were found and solved by this work are listed.更多还原
