We give direct experimental evidence for the observation of the full transverse self-
modulation of a long, relativistic proton bunch propagating through a dense plasma. The …

We measure the effects of transverse wakefields driven by a relativistic proton bunch in
plasma with densities of 2.1× 10 14 and 7.7× 10 14 electrons/cm 3. We show that these …

Particle-beam-driven plasma wakefield acceleration (PWFA) enables various novel high-
gradient techniques for powering future compact light-source and high-energy physics …

We study experimentally the longitudinal and transverse wakefields driven by a highly
relativistic proton bunch during self-modulation in plasma. We show that the wakefields' …

We show experimentally that an effect of motion of ions, observed in a plasma-based
accelerator, depends inversely on the plasma ion mass. The effect appears within a single …

We present a conceptual design for a hybrid laser-driven plasma wakefield accelerator
(LWFA) to beam-driven plasma wakefield accelerator (PWFA). In this set-up, the output …

Particle physics is addressing some of the grandest questions, armed with big science
machines: high energy particle colliders. These machines have, however, ballooned in size …

A plasma can sustain electric fields orders of magnitude larger than those attainable with the
conventional radio-frequency (RF) technology typically used in particle accelerators, which …

The European XFEL has planned to perform pump-probe experiments by using its x-ray
pulses and THz pulses. A promising concept to provide the THz pulses is to generate them …

We present a new method to determine the electron density of a plasma by measuring the
periodicity of modulations introduced to the longitudinal phase space of a relativistic particle …
