Mission
The JEOL ARM 200CF supports numerous research programs in the U.S. Department of Energy mission areas. Its uniqueness lies in its atomic resolution imaging and analytical characterization capabilities which are aided by energy dispersive X-ray spectroscopy, electron energy loss spectroscopy (EELS), and precession electron diffraction (PED).
The laboratory in which this instrument operates is designed to mitigate all carbon contamination on samples through the use of a vacuum heater which boils off hydrocarbons and then removes them through a turbo pump. Additionally, the instrument’s sample loading area is equipped with a Zeiss Stereoscope that allows users to check the cleanliness of the holder before insertion. Integrity and performance of the machine is paramount; experienced users of the instrument are available to assist in all aspects of your analysis.
