Automatic Aperture Mechanism (AAM) strip for FEI Sidewinder and Tomahawk FIB columns, standard configuration for 15 different beam currents.
Aperture sizes provide beam currents of:
|10pA||100pA, 2 ea.||1nA||10nA|
|30pA, 2 ea.||300pA||3nA, 2 ea.||MAX|
Aperture sizes increase over time due to ion sputtering. We recommend installing a new aperture strip when beam currents increase 10% above starting values.
Please note the MAX beam current available is typically 20nA or about 65nA, which depends on the configuration of the extractor assembly installed (not the aperture strip). So, if your Sidewinder column is currently limited to 20nA but want to upgrade to 65nA, just let us know you need the 65nA extractor assembly - it's that easy to triple the available beam current and milling throughput of your system! We specialize in custom aperture configurations to get the most out of your FIB operations - Contact Us for more information.
