Aperture Strip for FEI Sidewinder and Tomahawk FIB columns

SKU: 100153

Automatic Aperture Mechanism (AAM) strip for FEI Sidewinder and Tomahawk FIB columns with 15 different beam currents.

Aperture sizes provide 30kV beam currents of:

1.1pA 40pA 231pA 791pA 21000pA
7.7pA 80pA 426pA 2495pA 46600pA
23.8pA 80pA 791pA 9300pA 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 4035 273 67441, also described as STRIP,TOMAHAWK,#02(STRIP,BDA,15H,005)

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!
