PHI 600/660 Conversion Kit


A Schottky Field Emission source upgrade is available for customers with a Lab6 PHI 600 or 660 Scanning Auger instrument. The conversion from a LaB6 source to a Schottky Field Emission (FEG) source improves resolution, gives higher beam current and a longer lifetime (typically 8,000hrs based on average tests). The conversion is designed to make it easy for the customer to upgrade the system at their site with the minimum of interruption.

The package comprises vacuum hardware, power supplies and electronics to provide a seamless upgrade route to allow for the full benefits of Schottky field emission. Systems are available now for a number of electron optical probes and SEMs. These include PHI 595, PHI 600 and PHI 660 and the VG Scientific MICROLAB Auger instruments. Other electron optical probes and SEMs can also be converted. 

The full benefits of field emission for Auger micro-analysis are available to users of a PHI 595, PHI 600 and PHI 660 by upgrading with YPS's YPS3/P595 or YPS3/P660 packages. The conversion for the PHI 600 is identical whilst the PHI 595 differs owing to the horizontal orientation of the instrument.

The system performance with field emission is broadly equivalent to the column performance of the Broadly equivalent to Phi 680 at 10keV in terms of current in a given spot size. As a result users of installed and mature PHI Auger instruments can benefit from a very high micro-analytical performance without the expense of a new instrument.

The key technical features and customer benefits of the upgrade package are summarised below:
