摘要：

A differential energy-dispersive X-ray spectroscopy system has been assembled. It consists of a conventional Si(Li) or Ge solid-state detection unit whose output is routed to four 2048-channel segments of an EG&G ADCAM 100 MCA data acquisition system by logic signals from a control unit that operates at either 1 or 10 Hz. Operational details are given. The use of the system for electric-field modulation studies is also described and is illustrated by results from some 1280-rotated y-x cut slices of LiNbO3. These have been observed in fields up to 9 kV/mm in reflection and up to 2.8 kV/mm in transmission using synchrotron radiation. Some limitations of the present system are noted and some desirable modifications indicated.
