Symposium O: Nuclear Radiation Detection Materials

Symposium O: Nuclear Radiation Detection Materials Image

Session Topics | Invited Speakers | Symposium Organizers

This symposium will provide a venue for the presentation of the latest results and discussion of radiation detection materials from both experimental and theoretical standpoints. As advances are made in this area of materials, additional experimental and theoretical approaches are used to both guide the growth of materials and to characterize the materials that have a wide array of applications for detecting different types of radiation. The types of detector materials for semiconductors and scintillators include a variety of molecular compounds such as lanthanum halides (LaX3), zinc oxide (ZnO), lead iodide (PbI2), cadmium telluride (CdTe), mercuric iodide (HgI2), thallium bromide (TlBr), as well as others, such as cadmium zinc telluride (CZT). An additional class of scintillators includes those based on organic compounds and glasses. Ideally, desired materials used for radiation detection have attributes such as appropriate-range bandgaps, high atomic numbers of the central element, high densities, performance at room temperature, and strong mechanical properties, and are low cost in terms of their production. There are significant gaps in the knowledge related to these materials that are very important in making radiation detector materials that are higher quality in terms of their reproducible purity, homogeneity, and mechanical integrity. The topics that are the focal point of this symposium address these issues so that much better detectors may be made in the future.

Abstracts are solicited in, but not limited to, topics in the following areas:

  • Material growth: on-going developments regarding cadmium telluride (CdTe), cadmium zinc telluride (CZT), mercuric iodide (HgI2), cadmium manganese telluride (CMT), LaX3, and all other detector materials; new materials with potential for radiation detection (II-VI, III-VI, III-VII compounds, neutron detectors, nanomaterials, and ceramic scintillators); purification techniques; and growth methods
  • Characterization: experimental results; methodologies; defect structure; surface and bulk effects; and interfacial phenomena (contacting, contact adhesion, crystallographic polarity, Schottky barrier, and surface passivation)
  • Physical and mechanical properties: electric charge compensation mechanisms, charge collection, and thermal transport; hardness; and plasticity
  • New and innovative characterization techniques: optical spectroscopy; microscopy (SEM, TEM, STM, AFM, etc.); synchrotron mapping and X-ray diffraction; rocking curves; and spectroscopy (IR, Raman, NMR, XPS, Auger, and other applicable approaches)
  • Theoretical studies: bandgap calculations; mobility calculations; scintillator material physics; thermal modeling; crystal growth; processes in material matrices; and processes in amorphous and crystalline matrices

In addition to oral presentations, a poster session is planned.

Invited speakers include: Marcy Berding (SRI), David Black (National Inst. of Standards and Technology), Lynn Boatner (Oak Ridge National Lab), Nerine Cherepy (Lawrence Livermore National Lab), Jeffrey Derby (Univ.of Minnesota), Mark Goorsky (Univ. of California-Los Angeles), Bruce Harmon (Iowa State Univ.), Krishna Mandal (EIC Labs), Marek Moszynski (Soltan Inst. of Nuclear Studies, Poland), Andrzej Mycielski (Polish Academy of Sciences, Poland), Aleksandar Ostrogorsky (Rensselaer Polytechnic Inst.), David Singh (Oak Ridge National Lab), Mike Squillante (RMD Inc.), E.V.D. van Loef (Delft Univ. of Technology, The Netherlands), and William Yelon (Univ. of Missouri-Rolla).
