Detection properties and internal activity of newly developed La-containing scintillator crystals

International audienceIn this work, we will present the characterization, in terms of gamma response and internal activity of newly developed crystals that contains Lanthanum in their chemical formula. In particular we tested two LaBr 3 :Ce,Sr, one CLLBC and two CLLB crystals with different volumes. These crystals just overcome the prototype stage and, even if the production in still not standardized at least for large optics, they have been very recently commercialized in sizes interesting for high-energy gamma-ray spectroscopy, as for application in nuclear physics experiments. In particular, we will report on the study of the decay time, light yield and energy resolution with gamma rays, on the response as a function of the gamma interaction point and on the internal activity due to the presence of Lanthanum

3\u2033 7 3\u2033 LaBr3:Ce position sensitivity with multi-anode PMT readout

The response of a cylindrical continuous 3\u2033 7 3\u2033 LaBr3:Ce crystal coupled to four Position Sensitive photomultipliers (PSPMT) was studied using a 1 mm collimated beam of 662 keV gamma rays

Performances of a 1 '' x1 '' Cs2LiYCl6 scintillator detector

In this work we have measured the performances of a 1″×1″ sample of a CLYC scintillator (Cs 2 LiYCl 6 ) with 95% enrichment of 6 Li produced by RMD. Different PMT models, with borosilicate glass window or quartz window have been used. The Pulse line-shape and Pulse shape discrimination for different type of incident radiation (gamma-rays and thermal neutrons) have been investigated. The response to thermal neutrons has been measured using an AmBe source and a digital oscilloscope. A measurement of the internal radiation and the energy resolution for different gamma rays have been additionally performed. © 2013 IEEE.status: publishe
