S06_Novel materials (Orals)

Oral presentation

There has been renewed recent interest in organic-based radiation detection materials, owing to their unrivaled fast neutron discrimination capabilities and ability to tailor the scintillation properties for different applications. Existing examples of crystalline, liquid, and plastic organic scintillators meet a multitude of radiation detection needs but are largely characterized by...

S06_Novel materials (Orals)

Oral presentation

The report presents our achievement in the developments of all-solid state hybrid scintillators based on single crystalline films (SCF) and single crystals (SC) of mixed garnet compounds for registration of different types of particles and quanta in the mixed fluxes of ionizing radiations. Hybrid scintillators have been made in the form epitaxial structures containing one or two scintillators...

57. Discovery, crystal growth and scintillation properties of Tl-based scintillators

Prof. HongJoo Kim (Kyungpook National University)

S06_Novel materials (Orals)

Oral presentation

Thallium-(Tl)-based inorganic halide single-crystals are the potential new scintillators and our group has initiated a pioneer work on the research and development of these scintillators. For example, we have recently discovered and reported new cerium-activated-scintillators that include Tl2LiGdCl6/Br6, Tl2LiYCl6, Tl2LiLuCl6, Tl2LaCl5/Br5 [1-3], Tl2LiScCl6, and Tl2GdCl5. These scintillators...

26. Cesium Hafnium Chloride, a Non-Hygroscopic, High-Performance Scintillator

S06_Novel materials (Orals)

Oral presentation

Cesium hafnium chloride (CHC, Cs₂HfCl₆) is a recently-discovered scintillator with radiation detection properties superior to the incumbent detectors NaI(Tl) and CsI(Tl). Advantages of CHC include: an excellent energy resolution, no self-absorption, no self-activity, and non-hygroscopicity. Our first-grown crystals were measured to have a light yield of 30,000 ph/MeV and...

52. Neutron detection and High resolution imaging using large area 6LixNa1-xI:Eu

Dr Matthew S. J. Marshall (RMD Inc.)

S06_Novel materials (Orals)

Oral presentation

Here, we report on the synthesis and application of a novel scintillator material for neutron detection: a mixed halide compound: Eu-doped 6LixNa1-x (6LNI:Eu). 6LNI:Eu screens were made using physical vapor deposition. Additionally, we have grown single crystals of the same composition to compare with the thin films. In particular, a pseudo hot wall evaporation (HWE) approach was used to...

43. Scintillation properties of advanced LuAG:Ce optical ceramic materials

Dr Jiri A. Mares (Institute of Physics, AS CR)

S06_Novel materials (Orals)

Oral presentation

Detectors of ionizing radiation are widely used in the medical (CT, PET or PEM), homeland security fields and in scientific applications as electromagnetic calorimeters at CERN [1,2]. After 2000 year, the fast and efficient LuAG:Ce single crystal of garnet structure was developed [1] and its latest generation reached L.Y. ~27000 ph/MeV [2]. LuAG:Ce crystals grown by the Czochralski method from...
