Ph.D. | Homi Bhabha National Institute / Institute for Plasma Research 2018 — 2024

Designed a ring cusp ion source for $\text{Ar}^+$ beams ($1$ to $2\text{ keV}$, $100\text{ mA}$).
Utilized CST Studio for magnetic cusp optimization and OPERA-3D for ion optics design, achieving a low beam divergence of $\sim 6.5^\circ$.
Conducted transient thermo-structural analysis in ANSYS to design a grid mounting system that limited thermal deformation to $< 0.1\text{ mm}$.
Engineered a nine-channel Parallel Wire Array (PWA) and a Faraday Cup array (FCA) for real-time monitoring of ion beam profiles.

M.Tech. Nuclear Engineering | Pandit Deendayal Petroleum University 2015 — 2017

Developed a $10\text{ kW}$ Faraday cup capable of measuring $20$ to $30\text{ mA}$ beam intensities.
Designed cooling systems maintaining copper Faraday Cup at $350.6^\circ\text{C}$ for thermal integrity.
Calculated suppression voltages ($-450\text{V}$ to $-500\text{V}$) via SIMION 8.0 and LORENTZ.
