Prof Chakraborty upgraded the equipment by appropriately lowering the frequency of the RF voltage so that the QMS could handle the masses above 200 amu and also by converting the system into a full-fledged UHV-based Secondary Ion Mass Spectrometry (SIMS) Setup at Saha Institute of Nuclear Physics, Kolkata. Making use of the indigenous SIMS instrument, he initiated the experimental research on Ion-Matter Interactions, for which he was awarded "Premchand Roychand Scholarship (PRS)" and conferred "Mouat Medal" by the University of Calcutta in 1986. Later, he pursued research on Atomic Collisions in Solids, Inelastic Ion-Surface Collisions and Ion-Beam Modifications & Analysis of Materials. His other research areas include Low-Dimensional Materials and Nanoscale Systems, X-UV Optics, Optoelectronics, Nonlinear Optics, Photonics, Plasmonics, etc.
