this paper the defects in interline CCD matrix were studied, which appear as a
result of its irradiation with high-energy protons. Defects were studied in
different operation modes: in frames mode and in time delay and integration
(TDI) mode. By using a special organization of TDI mode we were able to
localize defects in vertical register with a precision of one pixel. The
dependence of the defects behavior on different system parameters was also studied,
such as: temperature, exposure time in frame mode, exposure time of every step
of integration in TDI mode, charge storage time in vertical register and number
of integration steps in TDI mode. Also a method of removal of the influence of
these defects directly during flight tests was developed and tested.
