Aperture Strip for FEI Sidewinder and Tomahawk FIB columns

SKU: 100424

Automatic Aperture Mechanism (AAM) strips for FEI Sidewinder and Tomahawk FIB columns, standard configuration for 15 different beam currents.

Aperture sizes provide 30kV beam currents of:

1.1pA 40pA 430pA 4100pa 30000pA
7.7pA 80pA 790pA 6400pA 47000pA
24pA 230pA 2500pA 14000pA 65000pA (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!

This item is a direct replacement for FEI p/n 4035 273 14911, also described as STRIP,AAM,HT-SW,STD.

We provide the full set of aperture strips for FEI/TFS FIB columns in the aperture size / beam current of your choosing.  Don't see what you're looking for? Just click the Contact Us link below!
