CSUN SEM Lab

I am the faculty Director of the CSUN Department of Geological Sciences' Scanning Electron Microscope (SEM) Lab. I began setting up the SEM lab as a user facility in 2011, and am advising CSUN undergraduate and MS student research involving EBSD analysis. We have a tungsten gun SEM that was installed in 2002 (the FEI Quanta 600), and we recently acquired a new field emission gun SEM (TESCAN MIRA4) through a NSF MRI grant - the largest MRI awarded in CSUN history. The FE-SEM was installed in 2022 and is now fully operational.

I welcome the opportunity to work collaboratively in the SEM lab with external users from academia or industry who are interested in imaging, EDS, or EBSD analysis of geologic materials. The user rates for the Quanta 600 W-filament E-SEM and the TESCAN MIRA4 FE-SEM are posted here. Please contact me by email (click HOME link at top left for email address) to inquire about the availability of lab research assistant help, analysis time, and to reserve a booking on the SEM calendar. We would appreciate the opportunity to be co-authors on any publications that result from data collected and/or processed in our lab. 

The lab is equipped with a FEI Quanta 600 W-filament SEM with SE, BSE, CL, EDS, and EBSD detectors: NOTE: EDS/EBSD capability temporarily down through Summer 2025

-Variable pressure modes: high vacuum, low vacuum, and environmental modes

-Oxford Instruments integrated EBSD + EDS system with Large Area Mapping function (AZtec Version 3.1) - down for repair

-Oxford Instruments Nordlys Nano ultrahigh sensitivity EBSD camera - down for repair

-Oxford Instruments 10 mm2 SiLi EDS detector with X-Stream2 pulse processor - down for repair

-Gatan MiniCL system (greyscale images only)
