Introduction to Transmission / Scanning Transmission and Analytical  Electron Microscopy
Monday, 6th February 2017
QUT Gardens Point, P Block
8:30am – 5:00pm

 

In this workshop we will review the basic instrumentation, operating modes and ancillary equipment available in today’s modern instrument, as well as discuss imaging (CTEM, STEM, HREM) and aberration correction, diffraction (SAED, CBED), and microanalysis (XEDS, EELS) techniques which facilitate materials characterization from the sub-millimeter to the sub-nanometer scales.  This workshop will serve as a good introduction to the techniques for the novice as well as a refresher for those who are returning to the field. The majority of the topics covered will be taken from materials science perspective, however, examples from the life sciences will be included as appropriate.

Focused Ion Beam Systems: Theory, Simulation and Application (FIB/HIM/SRIM)
Monday, 6th February 2017
University of Queensland, St Lucia Campus
8:30am – 5:00pm

 

The workshop aims to provide a better understanding of the underlying ion beam – sample interactions and mechanisms which take place when working with a FIB or HIM. Understanding these concepts is essential when designing experiments or working with difficult samples.

The workshop will start with an overview of the basic ion-solid interactions and most important concepts. The concepts are the same for HIM and Ga-FIBs.  A practical demonstration on the FEI Scios FIB will then illustrate the concepts on the device.  The focus of the workshop will be on the simulations of ion-beam solid interactions using the Program Stopping and Range of Ions in Matter (SRIM). We will take a look at the effect of sample tilt, acceleration voltages and compare the different ion beam species (He, Ne, Ga, Xe) to highlight the differences between the HIM (He, Ne), the Ga FIBs and Plasma Xe FIBs. Dr Sergey Rubanov will present practical application on Ga implantation in elemental semiconductors.  He will compare the simulations to experimental results. The workshop finishes with a presentation by John Notte about the unique sample interactions of light ions (HIM), and the different applications they enable.

8:30am – 12:30pm

This workshop will provide an overview of the principles by which three dimensional reconstructions can be generated from two dimensional projections of an object. The practical focus will be on the acquisition of tilt series in the transmission electron microscope using the popular, and freely available, software package SerialEM (http://bio3d.colorado.edu/SerialEM/). These tilt series will then be reconstructed into tomograms using IMOD (http://bio3d.colorado.edu/imod/) and visualisation and modelling will also be performed in this program.

Depending on the interest of the attendees, additional topics, such as subtomogram averaging or single particle analysis, or additional software programs, such as Amira, can also be discussed. Computing platforms will be provided for attendees, but they are also welcome to bring a laptop with IMOD installed on it.

Digital Micrograph Scripting
Tuesday, 7th February 2017
QUT Gardens Point, P Block
Half Day: 1:00pm – 5:00pm

 

This workshop will provide an introduction to writing and using scripts with Gatan’s DigitalMicrograph (DM) software. It is aimed at beginners who have little or no previous scripting/programming experience. Attendees will be provided with a package of script/images files on which to experiment and will have the opportunity to practice writing and testing some basic scripts of their own. The only prerequisite is that attendees bring along their own laptops on which they have installed the free offline version of DM (available from: http://www.gatan.com/installation-instructions). The older GMS 2 version of the software will be used by the presenter and is strongly recommended for this workshop.

 

Topics covered will include: how to create, run and install simple scripts; use of variables including images; operators – including logic operations such as AND and OR; a description of Gatan’s Document Object model and how to use it to apply various script commands to images, spectra and other types of data; carrying out repeating operations with IF and WHILE loops; inputting and outputting data to/from scripts; writing code as Functions; tips for debugging and good scripting practice; resources available for developing and sharing scripts. Although some of these terms may seem somewhat abstract, the workshop focus will be on explaining these concepts and showing how they can be applied to manipulate real-world microscopy data to extract useful information.
