Morphology and structure properties of columnar CsI films on optical fiber plate
Among scintillators, columnar CsI screens are used in applications detecting charged particles, UV light or X-ray for high energy physics and medical radiography. CsI scintillator can be grown in special microcolumnar form that preserves spatial resolution in thick coatings. We report on the columnar CsI films fabricated directly on optical-fiber plate by traditional vacuum deposition method. There morphology and structure were examined by scanning electron microscopy and X-ray diffraction. Properties of films depend on deposit condition are discussed.
