Beam profile indicator for swift heavy ions using phosphor afterglow

open access: yesAIP Advances, 2012
In this letter, we report a beam profile indicator for swift heavy ions (SHIs) which utilizes the afterglow of phosphors. Clear marks are left on SrAl2O4:Eu2+ and CaSrAl2Si2O8:Eu2+ samples by SHI irradiation through a permanent change of their afterglow ...

The Effect of Fast Kr Ion Irradiation on the Optical Absorption, Luminescence, and Raman Spectra of BaFBr Crystals

open access: yesCrystals, 2023
In this work, using photoluminescence (PL), optical absorption (OA), Raman spectroscopy (RS), and atomic force microscopy (AFM), the radiation damage of BaFBr crystals irradiated with 147 MeV 84Kr ions to fluences (1010–1014) cm2 was investigated.

Influence of swift heavy ions irradiation on optical and luminescence properties of Y3Al5O12 single crystals

open access: yesOptical Materials: X
Optical and luminescence properties of Y3Al5O12 (YAG) single crystals preliminary irradiated by swift heavy ions were studied. Swift heavy Xe ions with fluences ranging from 6·1010 to 2·1012 ions/cm2 were utilized for the irradiation of nominally undoped

Chemical modifications induced in bisphenol A polycarbonate by swift heavy ions

open access: yes, 2003
The chemical modifications in bisphenol A polycarbonate induced by swift heavy ion irradiation are analyzed in situ by means of Fourier transform infrared (FTIR) spectroscopy. Four beams (C-13, Ne-20, Ca-48, Xe-129) with energy of a few MeV/amu have been
