Saturday, 28 and Sunday 29 November have been set aside for pre-conference workshops, with Friday, 4 December being available for post conference workshops.

Workshops run separately from the conference with the workshop organisers being responsible for full arrangements and financial viability.

Workshop 1: TEM IMAGING

Friday 27th Nov 2015 & Friday 4th Dec 2015
The digital camera is an essential part of any TEM. It acquires the final data and the performance of the camera is critical to the success and productivity of the TEM. World class data can be obtained from older TEMs which have been upgraded with a modern, high specification camera. On Friday 27th November and Friday 4th December Gatan will present a “TEM Imaging”workshop, which is a mix of lectures and hands on experience with the new OneView camera. Participants will learn about the choices in camera hardware, techniques of digital imaging and image processing. For the first time in South Africa, the OneView camera will be shown. This is the only camera which provides 4K x 4K imaging at 25 frames per second, a revolution in usability and power. Sample drift need never be a problem again because real-time correction can be applied whilst imaging. The OneView camera can be fitted to any TEM, new or old; it will be installed on a JEM 2100F at University of Pretoria for this workshop. Pre-registration for the workshop is essential. Other opportunities for demonstrations will be available after the conference.

Workshop 2: CRYO TEM & CRYO SEM

Saturday 28th Nov 2015 Sunday 29th Nov 2015
Recent developments in hardware and accompanying software have greatly contributed to the employment of cryo-techniques for the preservation of cells for electron microscopy.
A TEM- and SEM course in cryo-techniques from sample preparation to microscope images, will be held in parallel on Saturday, 28th November 2015 at the Laboratory for Microscopy and Microanalysis, University of Pretoria. These courses will be repeated on Sunday, 29th November 2015.
Workshop presented by Dr Roland Fleck - Kings College London, Dr Andy Yarwood - Jeol UK and
Andreas Nowak - Leica Microsystems, Vienna

Workshop 3: EBSD & EDS

Saturday 28th Nov 2015 & Sunday 29th Nov 2015
Saturday 28th Nov 2015: Theory and practice of EBSD. Pattern generation and the importance of sample preparation. Kikuchi band detection and indexing. Phase identification. Considerations for angular accuracy. Simultaneous EDS and EBSD. EBSD in transmission - Transmission Kikuchi Diffraction (TKD); spatial resolution ~10x improvement .

Sunday 29th Nov 2015: Theory and practice of EDS. Theory of characteristic x-Ray production. Interaction volume and spatial resolution . Considerations for acquisition conditions.

Workshop 4: WORKSHOP IN CRYSTALLOGRAPHY

Saturday 28th Nov 2015 & Sunday 29th Nov 2015
The aim of Workshop in crystallography is to bring basic crystallographic knowledge to experts and young researchers working in a field of geosciences and material science. Through the historical development of crystallography and investigating minerals and crystallized materials different methods for investigation crystals, will be presented. Student and fellow participation are strongly encouraged.
Historical view – what is a crystal – definition of mineral and crystal, regularities, optical indices, angles between the crystal faces, crystal zones, macroscopic symmetry, – center, axes, mirrors – 3 hours
Symmetry – crystallographic axes, possible combinations of symmetrical operators, crystal classes, physical properties, projections: stereographic and gnomonic, different optical instruments and possibility for symmetry identification – optical indicatrix: microscope, spindle stage, goniometers - 6 hours
Crystallometry, goniometers, real crystals, choosing the crystals for measurement, crystal size, axial ratio, Miller’s indices, indexing of crystal faces, idealized crystals, crystal habit, crystal drawing, mistakes, computer programs for drawing, modern automatic goniometers – 5 hours

Workshop presented by Prof Vladimer Bermanec - University of Zagreb, Croatia

Workshop 5: TUTORIAL on Electron Diffraction Applications in TEM

Friday 4th Dec 2015
This workshop/tutorial will be focused on the applications of precession electron diffraction in TEM / from crystal structure determination to orientation imaging and strain mapping at nm scale. TEM orientation imaging , NBD strain mapping and solving ab-initio crystal structures using electron diffraction intensities. There will be also software demonstration for orientation imaging (ASTAR).

Workshop 6: Insight in 3D Non-destructive X-ray Microscopy

Friday 4th Dec 2015
3D X-ray microscopy has emerged as a powerful imaging technique that can obtain information from a variety of materials under a wide range of conditions and environments. Observing the evolution of microstructure in 3D on the identical region of a single sample can rapidly benefit microstructure modeling techniques. This is largely a unique capacity of X-ray tomography and several examples of in situ and ‘4D’ experiments will be presented, including crack propagation in ceramics, porosity and permeability characterization of porous functional materials, deformation of polymer foams under load and the evolution of defects in lithium ion battery materials and fuel cells, and others.

Workshop presented by Pete Lander - X-Ray Microscopy, Carl Zeiss Pty Ltd pete.lander@zeiss.com

Workshop 7: “The Geoscientists’ Micro-analytical Toolbox”

Friday 4th Dec 2015
A large number of microscopy-based techniques are now available to scientists in the geoscience research and industry fields, and the choice can be overwhelming. These techniques will be discussed and guidelines will be given to participants to make an informed decision on the appropriate technique for a specific sample. Presentations will provide examples of applications in geology and ore processing, and will therefore be of interest to geologists, mineralogists, metallurgists and material scientists, as well as any delegate wishing to learn more about these aspects of microscopy.

Workshop presented by Lesley Andrews

Workshop 8: “New Silicon Drift Detector technology speeds up EDS, EBSD and WDS spectroscopy:  seeing data you could never see before

Friday 4th Dec 2015
Recent advances in SDD technology enable remarkable improvements in EDS data collection, both in signal throughput and low energy sensitivity. This is made possible by the incorporation of CUBE Technology EDS modules with a new extremely robust Silicon Nitride (Si3N4) window. This new hardware extends the analytical capability of the EDAX TEAM system, a platform where all three technologies EDS, EBSD and WDSare integrated.

In this workshop the CUBE SDD technology will be discussed together with innovative mapping algorithms that allow quick determination of phase distributions and gives the user the possibility to search through a custom built spectrum library to find similar spectra and identify the unknown. The same algorithms are used in EBSD mapping to strongly increase the indexing success on poor quality patterns using the patented NPAR scan reprocessing function.
The new features will be highlighted using a live connection with our demo facility in Germany.
