    • Cathodoluminescnece (CL) Detector: Gatan Mono CL4
    • Raman (WD = 10mm)- WITec RISE with 785nm and 532nm laser
  • SEM Resolution: 1.0nm
  • Imaging mode
    • Resolution Mode (WD=5-10mm): high resolution and low depth of focus
    • Depth Mode: good resolution and increased depth of focus
    • Field Mode: large field of view, high depth of focus but worse resolution
    • Wide Field Mode (WD >25mm): extra large field of view but focus is not accurate
    • Channeling Mode: pivot point of scanning beam is on a single point on the sample
  • GM Chamber and Sample Stage
    • Internal Diameter: 340mm (width) x 315mm (depth)
    • Maximum Specimen Height: 145mm without rotation stage; 116 with rotation stage.
    • Maximum Specimen Weight: up to 8kg.
    • Movement: x,y: +/- 65mm,; z: 0 to 100mm. 100mm is where the stage is all the way down; Tilt +/- 90 degree.
    • Heating Stage: Kammarath & Weiss 1000°C maximum
    • Integrated Stage for Raman
  • Vacuum: Sputter Ion Pump and Molecular Drag Pump
    • High Vacuum Mode: < 9×10-3Pa
    • Low Vacuum Mode (UniVac): 7-500 Pa
  • PC and Software
    • SEM PC: MIRA3 Control Software
    • Raman PC: Control FIVE
    • EDAX PC: TEAM for both EDS and EBSD
    • CL PC: DMS 3 with DigiScan II
  • Sample Requirements
    • Not for magnetic materials, especially powder samples.
    • Samples must be compatible with high vacuum, i.e., clean and dry. Samples should be handled with tweezers or gloves.
    • Sample surface needs to be conductive and connected to ground (that is the stage), if not, the surface should be coated with a conductive layer, such Au or Carbon, then apply a conductive tape, Copper or Carbon tape, connected to the SEM stub. The stub should be tightened by screw.
