Location	Basement, 4/5 East End, TCD
Instrument	Tescan TIGER MIRA3 FEG-SEM equipped with motorised backscatter electron and colour cathodoluminescence detectors, two Oxford Instruments Ultim 170 mm2 detectors, Unity BEX detector and a WITec RISE Raman system. Fully quantitative point analysis (Astimex 53 calibration), superfast elemental mapping, mineral liberation analysis, and Aztec Live mapping with Oxford Instruments Aztec software, correlative Raman mapping.
Samples	Holds 2 x 2.5cm round epoxy mounts and 1 x 2.5 cm x 7.5 cm thin sections or 4 x 2.5cm round epoxy mounts Principally used for elemental analysis of polished thin section samples or imaging using BSE or CL detectors. Examples of samples analysed include silicate minerals, tephra, sulphides, apatite.
Additional information	The Tescan TIGER is a custom-built analytical instrument involving three companies from three countries; Tescan in the Czech Republic, Oxford Instruments in the United Kingdom, and WITec in Germany.
