      Presented by:
      Dr Sanjeev Kumar, Senior Scientist, London Centre for Nanotechnology, UCL.

      One of the most fascinating areas of research in mesoscopic physics is the transport properties of one-dimensional (1D) quantum wires.

      Recent experimental results of a low-density quasi-1D device fabricated using GaAs/AlGaAs heterostructure, with split-gates, top-gate combination to control the carrier density and confinement potential will be presented.

      Co-presenter:
      Dr Gustav Teleberg, Product Manager for ULT Platforms , Oxford Instruments.

      Dr Teleberg will present the latest developments in cryofree dilution refrigeration and its applicability to quantum technology. Integrated superconducting magnets, sample loading, RF wiring and cool-down accelerators are treated in some detail. Examples of recently built systems for research on quantum dots and nanowires, luminescence centres in silicon and superconducting qubit devices.

    • Particle Tracing Simulations with COMSOL Multiphysics® Particle Tracing Simulations with COMSOL Multiphysics® Dr. Edmund Dickinson Application Engineer COMSOL Recorded: Nov 11 2015 3:00 pm UTC 62 mins
    • The Particle Tracing Module extends the functionality of the COMSOL Multiphysics modelling environment, to allow the computation of the trajectories of particles in fluids and charged particles electromagnetic fields. The particles can be subjected to a wide variety of forces, such as electrical, drag, and thermophoretic forces, as well as particle-particle and fluid-particle interactions. This webinar introduces particle tracing for applications such as erosion, etching, mixing, filtration, mass spectrometry, ion optics, and beam physics. The webinar includes a demonstration and will end with a Q&A session.

      Edmund studied chemistry at the University of Oxford from 2004 to 2008. He then continued on for a doctorate at Oxford, researching the charge and mass transfer properties of electrolyte solutions. He joined COMSOL as an application engineer, where he specialises in chemistry, heat transfer and fluid flow.

    • CERN Scales their Complex Software Ecosystem with Automation CERN Scales their Complex Software Ecosystem with Automation Benedikt Hegner, Scientist with CERN’s development team Recorded: May 30 2012 9:00 am UTC 48 mins
    • European webinar- 10 AM BST / 11 AM CEST (this is the corrected time)
      No one said that finding out what the universe is made of and how it works would be easy. But at CERN, the European Organization for Nuclear Research, thousands of scientists are trying to do just that every day.

      The development team at CERN has created many applications including the ROOT platform, a big data analysis for its High Energy Physics computing. These applications are used by more than 20,000 users to create cutting edge scientific software. Understanding that the quality of their application is critical for its large customer base, CERN adopted Agile practices like Continuous Integration (CI) and testing.

      Please join this European webinar to hear how CERN implemented Electric Cloud’s scalable automation solution to build and test their complex software applications to improve their code quality and increase their release frequency.

      Join this webinar to learn:
      •How CERN validates their code quality when creating applications designed to identify the existence of sub-atomic particles
      •Why buildbot couldn’t scale to CERN’s needs
      •What benefits more than 20,000 users enjoy from CERN implementing Electric Cloud’s ElectricCommander solution

    • Low-dimensional Materials Characterization with Correlative Microscopy: Raman-AF Low-dimensional Materials Characterization with Correlative Microscopy: Raman-AF Dr. Ute Schmidt, Applications Manager, WITec GmbH Recorded: Oct 15 2015 2:00 pm UTC 61 mins
    • The aim of this webinar is to highlight the benefits of correlative microscopy for studies of graphene and related two-dimensional transition metal dichalogenides (TMDs) such as MoS2 and WS2. Raman Imaging is used to characterize the optoelectronic properties of 2D materials. In combination with AFM and SEM the precise geometric dimensions of these materials is determined. Photonic properties can be gained using SNOM.

      Key learning objectives are:

      Gain insight as to how unrivalled spectral and spatial resolution, ultra-fast acquisition times, and exceptional signal sensitivity in Raman Imaging can be combined with AFM, SNOM and SEM.

      Learn which properties of low dimensional materials can be characterized with Raman and how complementary techniques lead to a more comprehensive understanding of the sample.

      Learn how to configure a Raman microscope in order to perform high-sensitivity and high-resolution 3D spectral imaging routinely.

    • Electronic Recordkeeping In Radiation Oncology Electronic Recordkeeping In Radiation Oncology James P. Nunn, MS, CHP, DABR Senior Medical Physicist Lewis Gale Regional Cancer Center, Pulaski VA Recorded: Sep 23 2015 2:00 pm UTC 56 mins
    • Recordkeeping for purposes of regulatory compliance in the modern radiation oncology environment is largely a paper driven process. Many software and hardware solutions are available from vendors to solve individual issues relating to the collection and processing of QA data, but few, if any, can collect, process and present the results of this data in a cohesive way.

      This presentation will show how electronic recordkeeping is readily and routinely used in the setting of Radiology and Nuclear Medicine Service lines, but strangely absent in the Oncology service line. We will attempt to cover current offerings from oncology software vendors that aim to reduce the amount of paperwork and streamline the acquisition and processing of quality assurance data. In addition, we will provide an overview of the solution we are in the process of implementing at our facility.

      Goals and Objectives
      At the conclusion of the program, participants will be able to:

      -Identify the use of electronic recordkeeping in other areas of the hospital setting where radiation and radioactive materials are being utilized.

      - Assess the need for some form of comprehensive recordkeeping in Radiation Oncology.

      - Assess currently available offerings from vendors.

      - Discuss what our facility is implementing to fill this need

      Target Audience
      Medical Physicists, Oncology IT professionals, Oncology Administrators

      Approved for 1 credit ASRT, MDCB, MPCEC

    • Clinical Importance of Quality Assurance TG-142 for Medical Accelerators Clinical Importance of Quality Assurance TG-142 for Medical Accelerators Doug Moseley PhD, Assistant Professor, Department of Radiation Oncology, University of Toronto. Recorded: May 13 2015 3:00 pm UTC 60 mins
    • Complex treatment delivery techniques allowing faster and more accurate treatments are rapidly gaining clinical acceptance. These complex deliveries require a comprehensive approach to quality assurance that takes into account the types of treatments being delivered and the range of devices being used for delivery. The commonly used AAPM TG-142 report provides some guidance, but this shouldn’t be considered a stand-alone QA programme; it is a small piece in a comprehensive QA programme. A comprehensive QA programme requires equipment and devices, software, personnel, training, data recording, historical review tools, standard operating procedures, approval mechanisms, and an understanding of how the tests apply to your treatment system. Successfully implementing TG-142 requires more than simply conducting the tests listed in the tables; understanding the natural variation of processes, preparation and planning is also needed so that all the necessary aspects are considered to allow for safe delivery of complex treatment delivery techniques. Join Dr Moseley as he discusses the planning and decisions that are needed to be made so that you can succeed at implementing your TG-142 programme.
