DR. BINAYAK PANDA LOADS A SAMPLE IN THE IMS-6F SECONDARY ION MASS SPECTROSCOPE’S ULTRA HIGH VACUUM CHAMBER. IT IS CAPABLE OF ANALYZING VERY LIGHT ELEMENTS SUCH AS HYDROGEN AND LITHIUM IN ALLOYS. IT CAN ALSO ANALYZE VERY SMALL QUANTITIES OF IMPURITIES IN MATERIALS AT PARTS PER MILLION LEVELS, AND DETERMINE ISOTOPE RATIOS OF ELEMENTS, ALL IN SOLID SAMPLES.

jsc2021e029751 (7/15/2021) --- A diagram showing the the Process cycle of the Electromagnetic Levitator (EML) - Batch 3 of samples. EML is a multi-user facility that provides containerless melting and solidification of electrically conductive, spherical samples, under ultra-high vacuum and/or high gas-purity conditions. Heating and positioning of the sample is achieved by electromagnetic fields generated by a coil system. Batch 3 is a new Sample Chamber to be mounted to the EML process chamber, bringing 18 new samples
