Rhonda Stroud et al., NRL, to be published. Kate Burgess (ASEE Postdoctoral Fellow, NRL): “From achieving 80 pm spatial resolution ten days after the microscope’s delivery to obtaining single- atom-sensitivity EDX spectra in seconds, the Nion UltraSTEM has exceeded expectations. Any day you get an “Oh, wow!” from a visiting Nobel Prize winner looking at your latest data is a great day. At NRL with our new UltraSTEM, we have had this and more.” Left to right: Nabil Bassim, Kate Burgess, Todd Brintlinger and Rhonda Stroud (group leader) at the controls of NRL’s Nion UltraSTEM 200-X ™ UltraSTEM 100 & 200 ™ UltraSTEM-MC ™ (HERMES) UltraSTEM-X ™ (with EDXS) ...atomic-resolution EELS mapping & sub-Å imaging ...UltraSTEM capabilities plus vibrational spectroscopy ...UltraSTEM capabilities plus single-atom EDXS Si S 1 2 100mm² windowless SDD at 10.5mm ⇒ 0.7sr Nanodiamond EDXS of atom 1 (acq. time = 9.4 s) EDXS of atom 2 (acq. time = 8 s) 1nm E (keV) www.nion.com
