edit-john-fournelleDr. John Fournelle

John Fournelle is the director of the EPMA and SEM labs in the Department of Geoscience at the University of Wisconsin, Madison. His first electron probe experience was with a 3 spectrometer MAC probe at the Carnegie Institution Geophysical Lab in Washington DC around 1985, while pursuing his PhD at Johns Hopkins University, studying an Aleutian Island volcano. He then graduated to the Smithsonian’s 9 spectrometer ARL-SEMQ while doing a postdoc there studying anhydrite in the Colombian Nevado del Ruiz volcano. In 1992 he took over the UW Madison probe lab (ARL SEMQ) from Everett Glover, who had been one of the first researchers using CL in the 1960s while working the oil patch, creating the first luminoscope (Sippel & Glover, 1965, Science). A CAMECA SX51 in 1993 was followed by an SXFive FE in 2014. John has been teaching EPMA to students for 23 years at UW and is glad that many on the internet have also found his class notes useful. His EPMA-related research interests include low voltage EPMA (needed to study <1 micron Fe-silicides in lunar soil), chemical peak shifts (e.g. Mg, Al, Si Ka) in common silicate minerals, problematic alloys combining low Z and high Z elements, use of residual gas analyzers in electron probes, and development of EPMA reference materials.

He has been an organizer of three MAS Topical Conferences at UW-Madison (EPMA-2016; EBSD-2010; EBSD-2008) and is the MAS archivist. In his spare time he operates a ham radio station, WA3BTA, with cw on HF band. QRZ?
