JEOL "Flash & Go"™ Speeds Operation of ARM200F Cold FEG Transmission Electron Microscope
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 ...
