New Photonis XP20D0 photomultiplier for fast timing in nuclear medicine

“…3 presents the time spectra recorded with the LaBr 3 crystal coupled to the XP20D0, no. 2026, for 60 Co and 22 Na g-rays. The measured time resolution of 14074 and 20074 ps correspond to 10774 and 15475 ps, respectively for the LaBr 3 detector alone.…”

Growth and scintillation properties of Pr doped Gd3(Ga,Al)5O12 single crystals

“…More specifically, the Gd 3 þ site was substituted by Pr 3 þ according to the formula of (Pr y Gd 1-y ) 3 (Ga x Al 1-x ) 5 …”

“…[1] In past decades, scintillators with the best figure-of-merit given by a combination of stopping power, speed and light yield are the recently developed Ce-activated materials [2][3][4][5]. On the other hand, Pr 3 þ ion also shows the 5d-4f emission with the fast decay time in several host materials and such systems can be another candidate for high figure-of-merit scintillator.…”

Energy nonlinearity in radiation detection materials: Causes and consequences

“…Alkaline earth dihalides CaF 2 (Eu) [23] and BaF 2 [7] as well as some complex oxides including CdWO 4 [7], Gd 2 SiO 5 (Ce) [7], Lu 3 Al 5 O 12 (Sc) [7], Lu 2 SiO 5 (Ce) [25], Y 2 SiO 5 (Ce) [26] and bismuth germanate (Bi 4 Ge 3 O 12 ) [27] show a different nonlinear behavior: the specific light output rises by some 20-30% with increasing energy from around 10 to 100 keV, then levels out and remains approximately constant without decreasing again up to the highest published energy values. (Some of these materials also show a decrease of specific light output with increasing energy at very low energies, passing through a minumum near 8 keV.)…”
