Ionization-induced injection mechanism was introduced in 2010 to reduce the laser intensity threshold for controllable electron trapping wakefield accelerators (LWFA). However, usually it generates beams with continuous energy spectra. Subsequently, a dual-stage target separating and acceleration processes regarded as essential achieve narrow energy-spread by ionization injection. Recently, we numerically proposed self-truncation scenario of process based upon overshooting laser-focusing...
Abstract This research was to reveal the key factors in progression of osteoarthritis (OA) using non-targeted metabolomics and find targeted therapies for patients with OA. Twenty-two knee OA scheduled total arthroplasty were divided into two groups: Kellgren–Lawrence (KL) grade 3 ( n = 16) 4 6), according plain X-rays knee. After operation, cartilages femur samples analyzed metabolomics. When compared patients, levels choline, 2-propylpiperidine, rhamnose, monomethyl glutaric acid higher;...
It is demonstrated experimentally and by numerical simulations that the presence of a long-pulse-laser-created back plasma on target backside can focus relativistic electrons produced short-pulse laser interaction with front solid target. Comparing this to without plasma, number density fast increased one order magnitude, their divergence angle reduced fivefold. The effect attributed absence sheath electric field collimation megagauss self-generated baroclinic magnetic there. Such an...
Attosecond bursts of coherent synchrotronlike radiation are found when driving ultrathin relativistic electron disks in a quasi-one-dimensional regime wakefield acceleration, which the laser waist is larger than wake wavelength. The overcritical density shrink radially due to focusing wakefields, thus providing transverse currents for emission an intense, polarized, half-cycle pulse about 100 attoseconds duration. electromagnetic first focuses peak intensity...
In radiation pressure dominated laser ion acceleration schemes, transverse target deformation and Rayleigh-Taylor (RT)-like instability always develop quickly, break the structure, limit final accelerated energy, lower beam quality. To overcome these issues, we propose a design named dual parabola targets consisting of lateral thick part middle thin part, each with parabolic front surface different focus positions. By using such target, through interactive shaping processes, central will...
Abstract A scheme of generating ultra-intense attosecond pulses in ultra-relativistic laser interaction with under-dense plasmas is proposed. The pulse emission caused by an oscillating transverse current sheet formed electron density spike composed trapped electrons the wakefield and residual momentum left behind when its front strongly modulated. As soon as emerges, it tends to feed back further enhance current. Consequently, enhanced developed into a few cycles later until depleted out...
A method for producing dense attosecond electron sheets (tens nanometers thick corresponding to duration) and single intense light pulse is reported based on relativistic laser wakefields in underdense plasmas. By making use of gas targets this allows high repetition rates required applications.
