Mathieu Laurin (Université de Montréal)19/06/2014, 09:00Particle Physics / Physique des particules (PPD)Oral (Student, Not in Competition) / Orale (Étudiant(e), pas dans la compétition)Low energetic, elastic neutron scattering is an ideal tool to characterize dark matter detectors. At University of Montreal, we use our Tandem Van de Graaff accelerator to calibrate superheated liquid detectors of the PICASSO/PICO dark matter search experiment. Mono-energetic neutrons are produced via the 51V(p,n)51Cr nuclear reaction at well-defined resonance energies in the range of 4 to 120...Go to contribution page

Sjoerd Roorda (Université de Montréal)19/06/2014, 09:15Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)Oral (Non-Student) / orale (non-étudiant)Hyperuniform point patterns are characterized by a local variance that grows only as the surface area (rather than the volume) as the system gets larger and therefore do not possess infinite-wavelength fluctuations [F. Torquato & F.H. Stillinger, Phys. Rev. E **68**, 041113 (2003)]. Equivalently, it can be stated that for hyperuniform materials, the structure factor tends to zero for very...Go to contribution page

François Schiettekatte (Université de Montréal)19/06/2014, 09:30Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)Oral (Non-Student) / orale (non-étudiant)Current models of implantation damage annealing consider either point defect diffusion or damage complexes that anneal by processes internal to the complexes. However, neither of these models explains the broad shape or the heat release observed by nanocalorimetry. Here, we compare the heat release of 10 or 80 keV Si ions implanted at low-fluence (0.02-0.1 Si/nm2) in monocrystalline Si at 110...Go to contribution page

Lyudmila Goncharova (T)19/06/2014, 09:45Surface Science / Science des surfaces (DSS)Oral (Non-Student) / orale (non-étudiant)Modern synthetic approaches and nanofabrication are providing us the means of creating material structures controlled at the atomic scale. Familiar examples include the formation of hetero-structures grown with atomic precision, nanoparticles with designed electronic properties, and new carbon-based devices. One of the challenges here is that electron transport properties of these diverse...Go to contribution page

Peter Seidl (LBNL)19/06/2014, 10:00Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)Invited Speaker / Conférencier invitéA novel linear induction accelerator, the Neutralized Drift Compression eXperiment-II (NDCX-II), is currently being used at Berkeley Lab to explore intense beam physics and intense-beam material interactions. For the latter topic, fluences range from overlapping cascades of lattice disorder to eventually heating solids to ~1 eV on a timescale similar to the hydrodynamic expansion. This...Go to contribution page
