Atom probe tomography

The Invizo 6000 is a new generation atom probe that incorporates two key advances over the existing LEAP systems.

- New counter-electrode and double Einzel lens design that allows ultra-wide field of view
- Symmetrical deep UV (257.5nm) laser minimises bulk heating and improves specimen yield in challenging materials

These technologies are particularly beneficial on any materials that were previously too difficult to conduct a successful atom probe experiment usig the existing LEAP systems.

Voltage Pulse Local Electrode Atom Probe

The LEAP 3000 Si is a straight flight-path system which allows up to 200kHz high voltage pulsing for fast throughput, high data collection efficiency and large field of view. The flight-path length is variable, to allow user flexibility in choice of mass resolution versus field-of-view.

• Acquisition rate up to 10⁷ ions per hour.
• 10⁶ - 3 x 10⁷ atoms per specimen (typ.)
• Analysis volume: 50 x 50 x 100nm (typ.)
• Spacial resolution: 0.5nm
• Mass resolution: FWHM>1/1000

UV Laser Pulse Assisted Local Electrode Atom Probe

The 1 MHz 355 nm UV laser pulse allows the 3D analysis of composition and structure at atomic resolution in non-conductive systems such as ceramics, semiconductors, organics, glasses, oxide layers and even biological materials.

Our facility is recognised as a world-leading group in the interpretation and quantitative investigation of atom probe data reconstruction, utilising a combination of CAMECA IVAS/AP Suite, MathWorks MATLAB, and unique programming tools.
