Ai. Bolozdynya et Vl. Morgunov, MULTILAYER ELECTROLUMINESCENCE CAMERA - CONCEPT AND MONTE-CARLO STUDY, IEEE transactions on nuclear science, 45(3), 1998, pp. 1646-1655
A concept for a multilayer electroluminescent camera (MELC) for x- and
low energy gamma-ray imaging is presented. The MELC contains a stacke
d electrode structure immersed in a pressurized noble gas. The electro
des are made of a thin foil covered by photodetector arrays. A particu
lar design of the MELC based on wave-shifting fiber arrays optically c
oupled to external photodetectors is considered. The MELC allows about
a 1-mm three-dimensional position resolution with an energy resolutio
n roughly 1-2% at 140 keV, The number of readout channels can be no mo
re than 300 per layer per square meter of held of view. Total detectio
n efficiency depends on the number of layers and the gas pressure and
fare be comparable to that of solid state detectors. The count rate ca
n be anp to 10 MHz per layer. Computer simulations, undertaken to stud
y the feasibility of the MELC, and potential applications are describe
