We report on several experimental campaigns on laser-wakefield electron acceleration and radiation generation from laser-driven free electrons. Using a 60 TW-Ti:Sapphire laser, we routinely obtain stable electron beams with energies of up to 0.5 GeV, beam charge of 30-300 pC and bunch durations around 5fs. After passing a miniature undulator, a first all-laser driven X-ray undulator source...

Ionizing radiation in planetary orbits as in Earth’s Van Allen belt or the Jovian magnetospheres is a significant hazard for electronically and optical components aboard spacecraft’s. Hence a not negligible amount of time and expenses is spent for testing all radiation sensitive components before a mission.
This opens a novel field for LPAs which makes use of the inherent ability of LPAs to...

Electron beams from laser-plasma-accelerators often have rather large energy spreads and only limited
reproducilibility, which can be a showstopper for many key applications. Nevertheless, they have parameters which indicate
that they are highly suited as electron bunch drivers in plasma wakefield acceleration afterburner stages. For example, large energy spreads do not at all decrease...

The generation of ultra-short bunches is nowadays a critical requirement for plasma wave accelerators, on which many laboratories world-wide are investigating or close to start with experimental activities. This requirement is true for both, external injection into Laser Wake Field Accelerators, where injected beams need lengths close or shorter than 10 fs, or Plasma Wake Field Accelerations...

Laser Wakefield Acceleration experiments using the HERCULES laser system operating up to 200 TW at the University of Michigan will be described. High energy electron beams (up to 800 MeV) were produced along with energetic positrons, neutrons, gamma rays and spatially coherent x-rays using both gas jets and gas cells as targets. The measurement of scattered Raman radiation as a diagnostic of...

Laser-plasma acceleration has been experimentally studied at PEARL facility. Plasma wakefields excited by low-power laser have been observed in gas-filled capillary tube. Important theoretical results have been obtained and efficient numerical codes have been developed. PEARL-10 is under construction. It will provide power up to 5 PW.
The work is supported by Ministry of Science and...

A plasma wakefield acceleration experiment has been proposed to study the key issues in electron driven wakefield acceleration. A 250 MeV electron beam from the proposed FEL test facility so-called CLARA (Compact Linear Accelerator for Research and Applications) will get energy doubling with a ~ 20 cm plasma cell. In this talk, we will discuss the feasibility of electron beam transport and...

In light of the planned particle driven plasma wakefield acceleration experiment at CERN (AWAKE collaboration), particle beam self-modulation as proposed by Caldwell et al. has gained interest. Calculations and simulations show promising results but there is no direct experimental evidence yet. Therefore an effort was started at the Photo Injector Test Facility at DESY, Zeuthen Site (PITZ), to...

We have successfully demonstrated the driving of plasma wakefield by a square current profile electron bunch for the seeding for self-modulation instability (SMI) with 50pC bunches at the BNL-ATF. The experimental data is in excellent agreement with linear theory and OSIRIS-2D [1] simulation results [2]. Acquiring these results was possible because with low 50pC charge, the SMI does not grow...

A Proton Driven Plasma Wakefield Acceleration Experiment has been proposed as an approach to eventually accelerate an electron beam to the TeV energy range in a single plasma section. To verify this novel technique, a proof-of-principle demonstration experiment, AWAKE, is proposed using 400 GeV proton bunches from the SPS.
Detailed studies on the identification of the best site for the...

The AWAKE project at CERN is a proposed proof-of-principle experiment on the acceleration of electrons in a plasma wave excited by high-energy proton bunch. The 400 GeV proton bunch extracted from the SPS accelerator will pass through 10 m long plasma section. Plasma will be produced from Rb gas via photo-ionization by short laser pulse co-propagating with the proton bunch. In the first half...

The proposed proton-beam driven, plasma wake-field acceleration experiment AWAKE at CERN requires proton bunches with a high peak current and small transverse emittances extracted from the SPS at (300--400)~GeV. We present measurement results of bunch compression on the SPS flat top achieved by bunch rotation in longitudinal phase space for two optics available in the SPS. With the lower...
