CCD area image sensor
S8984-02
Front-illuminated FFT-CCD for X-ray imaging
The S8984-02 is an FFT-CCD image sensor suitable for X-ray imaging. The user can use the S8984-02 as an X-ray image
sensor by attaching a desired scintillator film to the faceplate. The S8984-02 is a variant of the S8984 and uses a FOP (fiber
optic plate) as the faceplate instead of a FOS (fiber optic plate with scintillator). The thickness of the FOP was also changed
from 1.5 mm to 10 mm, in order to increase resistance to X-ray irradiation.

Precautions
Operating and storage environment
· X-ray CCDs are not hermetically sealed, so avoid operating or storing them in high humidity locations.
· Do not store in locations subject to excessive vibrations.
· Do not use X-ray CCDs in equipment that requires special quality and reliability, and may directly affect human life or cause personal
injury if the equipment breaks down or malfunctions.
Deterioration by X-ray irradiation
· Like other X-ray detectors, X-ray CCD performance deteriorates due to X-ray irradiation, for example causing the dark current to increase and X-ray sensitivity to decrease. In some applications, the image sensor should be replaced as a consumable product.
Others
· If using an X-ray CCD for medical equipment, please contact your local HAMAMATSU sales office.
