Description
Atom probe tomography reconstructed data from APT specimen OREX-501071-100_1, analysed in laser-assisted mode. All valid data is in included, using an extended (epos) data format that allows generation of alternative spatial reconstructions if required. This data set contains a significant level of 69Ga contamination near the specimen surface due to ion implantation during specimen preparation with a monoisotopic 69Ga+ focussed ion beam. A mass peak at 43 Da (AlO+) associated with the 69Ga distribution may indicate the mobilisation of Al during specimen preparation. Overall, the data indicates a forsterite mineral phase with no apparent chemical inhomogeneities. A mass range definition file is included with all identified mass peaks.
