The SPI Supplies Fifteen Rare Earth Element Standard is mounted within a 1" (25 mm) diameter x 6 mm high disk, creating a mount that is UHV compatible and can be used with confidence in any UHV system. The mounts are carbon-coated providing conductivity from the metal or fluoride grains to electrical ground. Like all the other SPI standard mounts, there is a Faraday cup (FC) for the precise measurement of beam current.

The same items can be obtained in a half inch (12.5mm) diameter mount.
