Relativistic positron production with ultra-intense short-pulse lasers
Ultra-intense laser interactions with solid foils are studied as a means to produce relativistic positron plasmas, which has been proposed as a potential laboratory for understanding positron-electron plasma aspects of gamma-ray bursts [1]. Initial experiments with high energy Nd:glass lasers have revealed a strong dependence of the positron yield, and energy distribution, on the thin-foil targ...
متن کاملTechniques for Intense-Proton-Beam Profile Measurements
In a collaborative effort with industry and several national laboratories, the Accelerator Production of Tritium (APT) facility and the Spallation Neutron Source (SNS) linac are presently being designed and developed at Los Alamos National Laboratory (LANL). The APT facility is planned to accelerate a 100 mA H cw beam to 1.7 GeV and the SNS linac is planned to accelerate a 1 to 4 mA-average, H,...
متن کاملSub-TeV proton beam generation by ultra-intense laser irradiation of foil-and-gas target
A two-phase proton acceleration scheme using an ultra-intense laser pulse irradiating a proton foil with a tenuous heavier-ion plasma behind it is presented. The foil electrons are compressed and pushed out as a thin dense layer by the radiation pressure and propagate in the plasma behind at near the light speed. The protons are in turn accelerated by the resulting space-charge field and also e...
متن کاملEnergetic Proton Generation in Ultra-Intense Laser-solid Interactions
An explanation for the energetic ions observed in the PetaWatt experiments is presented. In solid target experiments with focused intensities exceeding 10 W/cm, high-energy electron generation, hard bremsstrahlung, and energetic protons have been observed on the backside of the target. In this report, we attempt to explain the physical process present that will explain the presence of these ene...
متن کاملPion Collection from an Intense Proton Beam in a Plasma
The μμ collider concept requires an intense proton beam smashing into a target to make pions that subsequently decay into muons. As described in the literature, the concept requires a high-field solenoid to enhance the effective final muon yield. Given the difficulty of maintaining the muon beam in the presence of muon decay, it seems interesting to consider concepts that preserve first the int...
