“…Electron beams with energies from tens to hundreds of kiloelectron-volts find wide application in various fields of science and technology (Mesyats, 2005;Li et al, 2006;Verbeeck et al, 2010). One of the most important parameters of electron beams is their energy spectrum.…”

“…Moreover, electrons of energy > eU m , where e is the electron charge and U m is the maximum gap voltage, are detected downstream of the anode foil of vacuum diodes at subnanosecond and nanosecond voltage pulse rise times (Khudyakova et al, 1964). The spectra of electron beams are measured with magnetic spectrometers (Bugaev et al, 1974;Mangles et al, 2004;Li et al, 2006) and time-of-flight spectrometers (Gloeckler & Hsieh, 1979). The spectra of nano-and subnanosecond electron beams are also measured with the use of different methods (Bugaev et al, 1974;Afanasiev et al, 2005;Baksht et al, 2007), including the measurements of beam current attenuation in foils of different thickness (Baksht et al, 2010).…”

Reconstruction of electron beam energy spectra for vacuum and gas diodes

et al. 2015

View full text Add to dashboard Cite

In this paper, the spectra of electron beams produced in vacuum and gas diodes were analyzed to study the capabilities and limitations of their reconstruction from beam attenuation in foils of different thickness. The electron energy distributions were calculated using the Tikhonov regularization for Fredholm integral equations on minimum a priori assumptions. The spectra reconstructed in the study were those of electron beams, including a supershort avalanche electron beam, produced in experiments on a DUET plasma-cathode electron accelerator and SLEP-150M accelerator.

“…This is different from the acceleration regime in previous works. 20,22,29,[42][43][44] The relativistic electrons can stay in phase with the co-moving laser electric field and be continuously accelerated for a long time until the laser pulse is reflected by the backside foil target.…”

Enhanced target normal sheath acceleration of protons from intense laser interaction with a cone-tube target

et al. 2016

View full text Add to dashboard Cite

Laser driven proton acceleration is proposed to be greatly enhanced by using a cone-tube target, which can be easily manufactured by current 3D-print technology. It is observed that energetic electron bunches are generated along the tube and accelerated to a much higher temperature by the combination of ponderomotive force and longitudinal electric field which is induced by the optical confinement of the laser field. As a result, a localized and enhanced sheath field is produced at the rear of the target and the maximum proton energy is about three-fold increased based on the two-dimentional particle-in-cell simulation results. It is demonstrated that by employing this advanced target scheme, the scaling of the proton energy versus the laser intensity is much beyond the normal target normal sheath acceleration (TNSA) case.

“…A strong negative azimuthal magnetic field B x , of the order of a few hundred megagauss, is created and it tends to confine the electrons. Since the hot electrons have speeds close to that of light, balance of the electric (eE y ) and magnetic (ev e B x =c) forces tends to confine and collimate the electrons, so that the latter can propagate stably along the grated surface [16].…”

Near-infrared radiation around 1000 nm generated from the interaction of a high-density MeV electron beam, obtained by impinging an intense ultrashort laser pulse on a solid target, with a metal grating is observed experimentally. Theoretical modeling and particle-in-cell simulation suggest that the radiation is caused by the Smith-Purcell mechanism. The results here indicate that tunable terahertz radiation with tens GV=m field strength can be achieved by using appropriate grating parameters.
