Tulchhi Ram

Plasma physicist with over 5 years of research experience in experimental plasma physics, specializing in cold plasma production using RF and DC techniques, vacuum systems, and electron cyclotron resonance heating (ECRH). Developed a compact, low-aspect ratio device (STARMA) with toroidal/poloidal field systems and integrated plasma diagnostics. Skilled in plasma characterization using Langmuir probes, optical emission spectroscopy, visible fast camera imaging, and B-dot probes. Experience in operating and maintaining UHV systems, and conducting full-wave and PIC simulations using COMSOL, CST, MEEP, and WarpX. As a visiting researcher at ITER, I contributed to the simulation and analysis of pre-ionization and ECWC-type plasmas. Experienced in working both independently and as part of a team. Highly motivated to work at the intersection of experimental and simulation-based plasma physics, with a focus on cold plasmas and plasma sources, and a growing interest in accelerator physics.
