Extractor assembly for systems using FEI Sidewinder or Tomahawk FIB columns. Please specify 21nA or 65nA maximum beam current.
Consists of assembled extractor cap, beam acceptance aperture, sputter shield and housing. We recommend a new extractor assembly be installed with each new 69Ga LMIS.
Please note the MAX beam current available is typically 20nA or about 60nA, which depends on the configuration of the extractor assembly installed (not the aperture strip) in your column. 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!
