Density of the solar flare plasma

Journal of Geophysical Research, 1962
Energetic particles are imbedded in solar material ejected at low energy and commonly called the solar flare plasma. The density of this plasma is highly uncertain. The density of the plasma is estimated from the interaction of the solar cosmic rays with the plasma.

Chirp Mitigation of Plasma-Accelerated Beams by a Modulated Plasma Density [PDF]

Physical Review Letters, 2017
Plasma-based accelerators offer the possibility to drive future compact light sources and high-energy physics applications. Achieving good beam quality, especially a small beam energy spread, is still one of the major challenges. For stable transport, the beam is located in the focusing region of the wakefield which covers only the slope of the ...

Reconfiguration of polar-cap plasma in the magnetic midnight sector [PDF]

, 2006
Radio tomography and the EISCAT and Super-DARN radars have been used to identify long-lived, high-altitude, cold plasma in the antisunward convective flow across the polar cap.

Collimation of fast electrons in critical density plasma channel [PDF]

, 2015
Significantly collimated fast electron beam with a divergence angle 10° (FWHM) is generated through the interaction of ultra-intense laser light with a uniform critical density plasma in experiments and 2D PIC simulations.

Polarized QED cascades

New Journal of Physics, 2021
By taking the spin and polarization of the electrons, positrons and photons into account in the strong-field QED processes of nonlinear Compton emission and pair production, we find that the growth rate of QED cascades in ultra-intense laser fields can ...

Rational Use of Herbal Products in Pediatric Patients Treated With Anticancer Drugs in the European Union

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The use of herbal medical preparation (HMP) is rising among pediatric oncology patients, often to manage treatment‐related symptoms. Their effectiveness remains uncertain, and the risk of herb–drug interactions is underestimated.

Design considerations for the use of laser-plasma accelerators for advanced space radiation studies [PDF]

, 2012
We present design considerations for the use of laser-plasma accelerators for mimicking space radiation and testing space-grade electronics. This novel application takes advantage of the inherent ability of laser-plasma accelerators to produce particle ...

Calibration of Swarm Plasma Densities Overestimation Using Neural Networks

Space Weather
Recent studies have shown that the measurements of Langmuir Probes (LPs) onboard ESA's Swarm mission overestimate ion densities on the nightside by up to 50%. The overestimation is due to the assumption of oxygen‐only plasma for ion density calculations,
