Welcome to the Nil's World of Physics

Hi everyone there,

This is Nilanjan Mukherjee here. Currently, I am working as a Senior Research Fellow (SRF) at Scottish Church College, Kolkata. My research interest focuses on electron collision studies on small molecules & molecular ions relevant for fusion tokamaks namely ITER (International Thermonuclear Experimental Reactor), ASDEX Upgrade (Axially Symmetric Divertor Experiment), EAST (Experimental Advanced Superconducting Tokamak) & JET (Joint European Torus) and also in low temperature plasmas occurring in astrophysics & industrial processes. I am presently involved in calculation of cross sections for electron induced processes such as elastic scattering, electronic and rotational excitation (for ions) and electron impact dissociation, using the R-matrix method, and also the construction of molecular states, both bound and resonant. The molecules we presently study occur as contaminants in the edge plasma. Therefore, the cross-sections and molecular data are vital for modelling plasma flow in the edge region, predicting impurity radiative losses in the plasma and for maintaining the stability of the plasma-facing components in the edge region. 

I am also interested in the spectroscopic measurements which allow to discern the spectral fingerprints of various elements and ions present in the plasma. This not only facilitates a comprehensive understanding of the temperature, density, and composition of the plasma but also provides crucial data for optimizing and fine-tuning the conditions necessary for sustained nuclear fusion.
