  5. erate e−e+ pairs by highly intense laser pulses and effectively accelerate positrons in plasmas can be, however, harnessed to build a one-stage plasma-based positron accelerator. Recently, an arrangement where the pair production is initiated inside a plasma wakefield wave, which provides the instantaneous acceleration, has been proposed58 ...

    Pair production is one of the fundamental quantum electrodynamics (QED) effects, which is potentially interesting for a variety of applications 1,2,3, such as fundamental nuclear and particle physics, laboratory astrophysics and plasma physics, radiography for material science and medical applications.For example, GeV and even TeV positron beams are required for studying highly energetic ...

    Feb 24, 2023For example, we may learn how to take advantage of plasma pair processes to develop more efficient accelerators and radiation sources," Fiuza said.

  8. A more sophisticated description for e e+ pair production by taking into account the e e+ spin and -photon polarization has been discussed [30,44,45], based on single-particle model analyses or simulations. The photon polarization is shown to signi cantly reduce the pair yield by a factor of over 10% in the collision of ultraintense laser pulse

    When a high-intensity laser pulse (≥10 23 W cm −2) irradiates a solid target, electrons in the strong laser field can be accelerated to extremely high energy, so that a new regime beyond relativistic plasma can be entered , dominated by quantum electrodynamics (QED) effects such as pair production [11-16] and cascade development [17-21].

    Oct 22, 2024The physics of the creation of electron-hole (e − -h +) pairs upon the absorption of radiation quanta (e.g., x rays, γ rays, fast electrons, etc.) with energy ≫ the bandgap ⁠, E g, in semiconductors is still relatively poorly understood.The topic has always been of critical importance in radiation detection as it is the basis of many particle and photon counting spectrometers, but ...

    Jun 1, 2024In such ultra-intense laser fields, the emitted photons are capable of decaying into lepton pairs via Breit-Wheeler (BW) process and copious matter and antimatter can be generated in the form of electron-positron or muon pairs, forming the so-called \(e^+e^-\gamma\) plasma or QED plasma (Masood 2019). Especially, the QED process and plasma ...
