Advanced Microscopy Laboratory (AML)

The Microscopy and The Advanced Microscopy Laboratory (AML) at Oak Ridge National Lab (ORNL) is a world-leading facility housing 4 aberration-corrected STEMs. Designed and constructed to provide the best environment for aberration-corrected electron optical instrumentation, the AML has been a great success. Minimization of AC magnetic fields, floor vibrations, air flow volume, temperature stability and acoustic sound were key design criteria. Special construction practices were followed to ensure optimum building performance.

Air flow: < 2 cm/s Temperature stability: < ±0.1°C/h Magnetic stray fields, ambient: ~0.05 mG rms @ 60 Hz Floor vibrations: < 1µm/s peak @ < 30 Hz Aberration-corrected microscopes housed in AML: JEOL 2200FS, FEI Titan-S, VG HB-501, VG HB-603
