National Facility For Atom Probe Tomography

Location: ACMS 112

National Facility for Atom Probe Tomography (NFAPT) houses the state of art atom probe tomography (APT), latest cutting edge technology "Local Electrode Atom Probe (LEAP 5000 XR)" along with "Helios Dual Beam Scanning Electron Microscope with Focussed Ion Beam (FIB)" for LEAP sample preparation. The group of eight founding partner institutions (IIT Madras, IIT Bombay, IIT Delhi, IIT Kanpur, IIT Kharagpur, IIT Ropar, ARCI Hyderabad/Chennai and BRNS) have the remotely operable module empowering independent online operational capability of LEAP. This is the first remotely operable LEAP facility in the world. Any researcher in India is welcome to use the facility by contacting the coordinator.
