Thin scintillator CsI(Tl) films for precise tomography. Development and applications.
0.5-20 μm thin CsI:Tl scintillation screens with high spatial resolution were pre- pared by the thermal deposition method. It was proposed that the spatial resolution of the prepared conversion screens can be significantly improved by an additional substrate heating as well as by deposition of a carbon layer. Also thin CsI:Tl films deposited on mylar substrates can be used for non-destructive diagnostics of the spatial profiles of low energy beams of charged particles. We present the characteristics of the scintillators in dependence on the type and temperature of the substrates.
