“…The studied case is one of the candidates for inert matrix fuels and alternative waste immobilization matrix, MgAl 2 O 4 (Zinkle and Snead 1996; Georgenthum et al 2001;Pantelica et al 2005;Schram et al 2003; Abstract A comparative study of damage accumulation in magnesium aluminate spinel (MgAl 2 O 4 ) has been conducted using ionoluminescence (IL), cathodoluminescence (CL) and Rutherford Backscattering Spectrometry/ channeling (RBS/C) techniques. MgAl 2 O 4 single crystal and polycrystalline samples were irradiated with 320 keV Ar + ions at fluencies ranging from 1 × 10 12 to 2 × 10 16 cm −2 in order to create various levels of radiation damage.…”

International audienceA comparative study of damage accumulation in magnesium aluminate spinel (MgAl2O4) has been conducted using ionoluminescence (IL), cathodoluminescence (CL) and Rutherford Backscattering Spectrometry/channeling (RBS/C) techniques. MgAl2O4 single crystal and polycrystalline samples were irradiated with 320 keV Ar+ ions at fluencies ranging from 1 × 1012 to 2 × 1016 cm−2 in order to create various levels of radiation damage. RBS/C measurements provided quantitative data about damage concentration in the samples. These values were then compared to the luminescence measurements. The results obtained by IL and RBS/C methods demonstrate a two-step character of damage buildup process. The CL data analysis points to the three-step damage accumulation mechanism involving the first defect transformation at fluencies of about 1013 cm−2 and second at about 1015 cm−2. The rate of changes resulting from the formation of nonluminescent recombination centers is clearly nonlinear and cannot be described in terms of continuous accumulation of point defects. Both, IL and CL techniques, appear as new, complementary tools bringing new possibilities in the damage accumulation studies in single- and polycrystalline materials

“…Up to 2012, in Romania, nuclear physics research with accelerated ion beams was mainly performed with the HVEC 9 MV FN tandem accelerator, system that was commissioned in 1973 [5][6][7]. Starting in 2006, a series of hardware upgrades transformed the 9 MV tandem accelerator in a very reliable and modern machine [8][9][10], capable to provide around 5000 h of beam time per year.…”
