    Sample holder with 5 silicon samples mounted to the cold finger and ready to be installed into the vacuum chamber.

    Cold finger inside the Scienta 200U prep chamber with all 5 samples at about 19 Kelvin.  Also visible in this view are the LEED shutter (behind the cold finger), a thickness monitor (right foreground), and liquid cooled evaporator shroud (right background).

    Heating the middle sample to about 1000 Celcius by passing electric current through it while the rest of the samples remain at cryogenic temperatures.

    Heating the middle sample more.
