37. ExB Plasmas Generated by e-beams and non-thermal electrons for processing two-dimensional materials including negative ions and applications

Yevgeny Raitses (Princeton Plasma Physics Laboratory)

9/24/26, 10:10 AM

Invited

There is a growing interest in the use of low temperature magnetized plasmas generated by electron beams and non-thermal electrons for processing of materials at atomic scale with applications to microelectronics and quantum systems.[1-3] For these applications, the plasma (density ~ 109-1010 cm-3 and electron temperature ~ 0.1-0.5 eV) is typically generated by injecting an energetic (102 –...

163. Charged particle transport in electronegative plasmas by particle-in-cell calculations

Emile Carbone (Institut National de la Recherche Scientifique - Centre Énergie Matériaux Télécommunications)

9/24/26, 10:35 AM

Invited

Electron and ion transport in non-equilibrium plasmas is inherently complex, exhibiting intricate behaviour in the phase space and in time. The Particle-In-Cell (PIC) method is widely used, being close to first principles and requiring few input parameters, enabling self-consistent simulations. Macroscopic particle transport is governed through collision phenomena and microscopic dynamics [1]....

47. Implicit PIC Simulations of Negative Hydrogen Plasmas with Intense Negative Ion Production

Dr Denis Eremin (Ruhr University Bochum)

9/24/26, 11:00 AM

Invited

High-density plasma discharges in hydrogen operating at low pressures are of considerable interest for negative ion production used in many applications. Their weak collisionality requires a kinetic, nonlocal description, and a popular approach is to model such discharges numerically using the particle-in-cell (PIC) method combined with Monte Carlo collisions (MCC). However, the most commonly...

46. A Comparison of Implicit and Explicit PIC Schemes in One Dimension

Nicolas Savard

9/24/26, 11:25 AM

Invited

Explicit particle-in-cell (PIC) codes are widely used to study the physics of plasma ion sources. However, in higher-dimensional simulations of high-density, low-temperature plasmas, computational cost becomes a major limitation due to the need to resolve the Debye length and plasma frequency timescales. Fully implicit, energy-and-charge-conserving PIC schemes offer the advantage of relaxing...
