Similar to MCA but distinguished by turbomolecular pressure & speed. An optional optical microscope can be installed to mount and observe specimens during plasma conditioning and potential leak observation from liquid/gas specimen cells. Plasma processing at lower vacuum increases plasma processing activity. To meet requirements of viewing gas and liquid sample cells in TEM holders the Chiaro performs the functions of leak checking, gas/liquid E-Chip viewing while mounting, surface hydrophilization and plasma processing.
