The Sensitive High Resolution Ion MicroProbe (SHRIMP) measures ions on the 10-30 micron diameter and a few micrometers deep in solid materials.
Users typically measure:
- stable isotopes (O, S, C) to understand past environments in geological and archeological materials
- volatile elements (C, H, S, N) to track geochemical cycles in planets
- trace elements for understanding rock histories and materials synthesis
- U-Pb for dating and understanding geologic histories.
ANU designed and developed the SHRIMP instrument and the lab currently includes: SHRIMP II, RG (reverse geometry) and SI (stable isotope). SHRIMP instruments are found in a number of laboratories overseas.
The group also oversees sample preparation facilities, Scanning Electron Microscopy, plus confocal and petrographic microscopes.
