The technique uses new luminescent aluminum oxide single crystals having aggregate oxygen vacancy defects and doped with Mg (Al2O3: C,Mg) in combination with laser scanning confocal fluorescence microscopy. Spectroscopic capabilities of this new method were demonstrated for energetic heavy ions of LET_Inf_H2O ranging from 2.2 to 8767 keV/um. The new technology is intended for use in neutron detection and dosimetry, proton and heavy ion radiobiology, and space radiation dosimetry as well as in nuclear and particle physics research.}, pages = {422--426}, title = {Spectroscopic properties of novel fluorescent nuclear track detectors for high and low LET charged particles}, volume = {43}, year = {2008} }
