From July 1992 to February 2020, I ran the UW-Madison electron microprobe and SEM labs. This lab consists of a CAMECA SXFive Field Emission electron microprobe #944, installed in late 2014, a CAMECA SX51 electron microprobe #485, installed in late 1993, and a Hitachi S3400 VP-SEM.  Dr Will Nachlas [link to his page] is now the Director of these electron beam instruments. Please contact him if you are interested in access to these instruments.  While I retired from directing the operation of the electron probes and SEM, I continue to be very active with many research projects, some funded by NSF with research scientist Aurelien Moy, on “low kV EPMA”. Other projects include chemical peak shifts in Mg, Al and Si Ka X-rays; development of some mineral standards for EPMA; and assorted “problems” in EPMA (such as errors measuring Hf in zircon). A team of myself and 3 colleagues wrote an <up-to-date summary of EPMA> [link to doi.org/10.1016/j.pmatsci.2020.100673] for Progress in Materials Science (Llovet Moy Pinard Fournelle).
