Plasma Physics / Physique des plasmas (DPP)

Invited Speaker / Conférencier(ère) invité(e)

Magnetic reconnection is a fundamental process that leads to rapid energy conversion in astrophysical, space and laboratory plasma systems. In modeling this process, most of the plasma fluid equations have employed an electrical resistivity to generate the magnetic dissipation required for magnetic reconnection to occur in a collisionless plasma. However, there has been no clear evidence that...

Invited Speaker / Conférencier(ère) invité(e)

Our group has recently demonstrated that relativistic electron acceleration can be achieved directly in ambient air by tightly focusing few-cycle infrared pulses with high-numerical-aperture optics, using mJ-class femtosecond laser systems. Owing to minimal B-integral accumulation which prevents intensity clamping, relativistic peak intensities approaching 1e19 W/cm² have been achieved,...

502. High-Energy Electron Acceleration in Nonlinear Laser Wakefield Regimes

Plasma Physics / Physique des plasmas (DPP)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

Laser wakefield acceleration (LWFA) enables ultra-compact, multi-GeV electron sources, offering a promising route toward next-generation accelerators for medical, industrial, and high-energy physics applications. Using multi-dimensional PIC simulations with SMILEI, this work examines nonlinear wakefield evolution in a two-stage LWFA configuration. In the first stage, a relativistically intense...

839. XUV Diagnostic System for Measuring the Focusing of Protons Produced by High Intensity Laser Pulses

Plasma Physics / Physique des plasmas (DPP)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

High intensity (≥1018 W/cm2) short pulse (≤ps) lasers allow the efficient generation of MeV energy protons from thin foils. Since the protons are emitted perpendicular to the rear surface of the foil, hemispherical foils may act to focus the protons [1-3]. This focusing is crucial to achieving sufficient proton flux on target for the proton fast ignition scheme of inertial confinement fusion....

937. Examining the impact of laser spot size and laser energy on nanosecond laser ablation to enhance laser-induced breakdown spectroscopy

Plasma Physics / Physique des plasmas (DPP)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Understanding the complex nonlinear physical processes involved in laser ablation remains a challenge. A fundamental understanding of laser ablation can greatly aid in determining optimal parameters for detection techniques such as laser-induced breakdown spectroscopy (LIBS), a high-sensitivity technique for measuring the elemental composition of a material using an energetic laser to produce...
