Home > Press > JEOL “Flash & Go”TM Speeds Operation of ARM200F Cold FEG Transmission Electron Microscope

Abstract:
JEOL's atomic resolution Transmission Electron Microscope (TEM), the JEM-ARM200F, sets a new standard for rapidly resuming operation after flashing, a routine procedure conducted with any TEM featuring a Cold FEG source. Long considered a tradeoff for the higher resolution, higher brightness, and smaller energy spread of a cold FEG TEM, emission stability degrades due to residual gases in the area of the tip. With conventional cold FEG TEMs, the operator must flash every few hours to clean the tip, disrupting operation.
The JEOL ARM200F Cold FEG TEM has the unique ability to "Flash & Go," allowing the microscope to resume operation within seconds after flashing, instead of the typical half hour or more that most users of Cold FEG TEMs expect. A newly developed vacuum system effectively evacuates the area around the Cold FEG source to the order of 1 x 10-9 Pa, resulting in outstanding long term emission stability.

JEOL “Flash & Go”TM Speeds Operation of ARM200F Cold FEG Transmission Electron Microscope

Posted on May 9th, 2011

The ARM200F with Cold Field Emission Gun represents a radical departure from electron optical technology, achieving unprecedented imaging resolution of 78 picometers with an energy resolution of better than 0.3eV. The higher brightness and narrower energy spread enabled by the Cold FEG are optimized by the ultra stable emission, greatly enhancing atom-atom imaging and chemical analysis.
