Small-size pulsed X-ray source for measurements of scintillator decay time constants

Scintillation properties of ceramics based on zinc oxide

“…The emission spectra were measured at a steady state X-ray excitation (40 kV, 10 mA) with a photomulplier tube FEU-106 and a MDR-2 grating monochromator with 1200 lines/mm. The same set-up was used for measurement of TSL in the range from 80 to 500 K. The kinetic curves were recorded at pulsed (< 1 ns) X-ray excitation using standard START-STOP detection system described elsewhere (Rodnyi et al, 2001). The emission spectra were measured in the reflection mode: the angle between a X-ray beam and a photomulplier was 90 • .…”

Light emission efficiency and imaging performance of powder scintillator under x‐ray radiography conditions

“…3 Since most Si and CMOS based photodetectors are more sensitive to longer wavelength ranges, and particularly in the red wavelength range, it would be of interest to investigate the emission efficiency of red emitting phosphors. [6][7][8][9] Such phosphors can be easily prepared by inserting europium ion activator ͑Eu 3+ ͒ in rare earth based host matrices. Furthermore, many europium doped scintillators, and particularly Gd 2 O 2 S : Eu, have been previously found comparable to terbium-activated phosphors in terms of optical output.…”

Optical, luminescence, and scintillation properties of ZnO and ZnO:Ga ceramics

“…15 An x-ray source with pulse width ഛ1 ns, operating at a voltage of 30 kV and a maximum current amplitude of 500 mA, was used to excite the samples. The recording layout consisted of an FÉU 71 photomultiplier, operating in the photon-counting regime, and the accompanying electronics, which allowed measurements to be made in various time ranges with a resolution no worse than 100 ps.…”
