We are developing a public-license electron-microscope column referred to as NanoMi, whose electron optics is suspended inside a vacuum envelope based on ConFlat hardware, see Fig. 1. The design of individual components has been reported earlier. We are now developing software control, column alignment procedures and integration of the components. A significant part of the work has been done by undergraduate students in our laboratory. Parts of the software and modeling are available for download from GitHub and from Open Science Foundation sites and are released under a GPL v3 license. An initial version of the blueprints is now shared on case-by-case basis.

Bright field transmission electron microscope (BFTEM) images are often used to measure sample size in two dimensions (2D). Mass thickness (rt) maps of the sample along the electron beam direction, although measurable with a monolayer precision [1,2], are seldom obtained. To measure rt, a calibration sample is needed. We show that calibration can be obtained in-situ using multi wall carbon nanotubes (MWCNTs).

Chris Bradbrook, Goldcorp. Inc. -- Clearly the performance of the Red Lake mine is our biggest news. Since commencing commercial production at the beginning of 2001 the mine has continually exceeded all forecasts. It is the richest gold mine in the world and operates with one of the lowest cash and total costs in the business. The Red Lake mine has transformed Goldcorp. The most important point to make is that we have achieved this transformation through organic growth, which has enabled us to create real shareholder value. For example, our historic finding costs have been approximately US$11 per reserve ounce and we are able to mine these at a cost of less than US$65 per ounce. Our exploration efforts have continued to meet with success and last year (2001) we were able to increase reserves and extend the mine life, thus further enhancing shareholder value. Currently we are conducting our largest-ever exploration program at the mine with a 2002 budget of US$12 million.
