    A 25 J-1.053 μm pulse in 0.45 ps (a[sub 0]= 2.2) was injected into a gas jet. This excited a large amplitude self-modulated wakefield. By increasing the pulse length from 0.45 to to 1.2 ps, the wakefield grew close to the wave-breaking limit, which sustained a 350 ± 150 GV/m acceleration...

    The structure of a picosecond (∼ 150 ps) electron beam in the cathode-anode gap of a vacuum diode is determined. The electron beam is modeled in the form of flat quasiparticles with a definite charge density which follow one after another in equal time intervals. It is shown that the...

    The RF photoinjector, when coupled with a magnetic pulse compression system, is now a ubiquitous tool for production of sub-picosecond electron beam pulses which are to be used in advanced accelerator and light source experiments. As the time-scale for both pulse lengths and synchronization to...

    We present the status of the LILAC experiment [1], including results on the propagation of 30-fs duration laser pulses in plasmas of the requisite density, and measurements of the dark current [2]. We also discuss the status of a laser upgrade, an electron beam line and plans for the future.

    We discuss an excitation scheme, where the interaction of two ultrashort laser pulses prepares an ensemble of ionized molecules with an oscillating average bond length. By adjusting the delay-time between the pulses it is possible to vary the oscillation period continuously within the...
