Laser-Plasma accelerators (LPAs) promise a compact alternative to modern RF-technology. However, the central energy jitter and energy spread, both on the percent-level, have so far prevented LPAs to drive real-world applications. Here, we experimentally demonstrate active energy compression of a laser-plasma accelerated electron beam. At the LUX experiment at DESY, a dipole chicane stretches...
The Central Laser Facility are constructing the Extreme Photonics Applications Centre (EPAC), aiming to become operational as a user facility in 2027. EPAC will house a 10 Hz, 1 PW laser serving two independent experimental areas. The first area to come online is configured as a long focus beamline, predominantly for developing laser wakefield acceleration in gas targets. I will describe the...
Laser wakefield accelerators (LWFAs) represent a transformative breakthrough in particle acceleration, achieving acceleration gradients 1,000 times higher than conventional radiofrequency-based accelerators. This revolutionary technology promises substantial reductions in the size and cost of accelerator-based systems, potentially paving the way for the next-generation compact light sources...
The MULTISCAN 3D project aims to provide a technical solution to create 3D tomography systems capable of detecting threats invisible with current 2D technology. Laser-plasma acceleration appears to be a promising method, generating ultrashort and highly charged electron beams converted into versatile X-ray sources. Being flexible, laser-plasma accelerator offers multiple sources in a compact...
Bright X-ray beams with narrow bandwidth and tunable energy can lead to various novel applications. Compact all-optical inverse Compton scattering X-ray sources show great potential as alternatives to large-scale synchrotron sources to democratise access to such beams. However, all-optical ICS sources are yet to demonstrate percent-level bandwidths, a key requirement for many applications....
There has been growing interest in using very high energy (100-300 MeV) electrons for radiotherapy, both using conventional and plasma-based sources. While not as precise as ions, ultra-relativistic electrons offer a more favorable dose deposition profile than X-rays, potentially reducing the irradiation of healthy tissue. Laser-plasma sources of ions and electrons could offer cheaper and more...
Laser-based particle sources allow for investigating biological effects of radiation at high instantaneous dose rates. We have run two experiments including the irradiation of monolayer cell cultures at total dose values of 3-12 Gy.
At the Laser Laboratory for Acceleration and Applications (L2A2) an X-ray source driven by a 35 fs pulsed laser with 1 mJ pulse energy at 1 kHz shot rate,...
Laser-Plasma Accelerators (LPAs) can reliably generate Very High Energy Electrons (VHEE, >50โฏMeV), a promising radiotherapy modality due to their favorable depth-dose profiles and potential for ultra-high dose-rates required for FLASH therapy. While most biological studies involving LPAs focus on beam energy and dose target, the temporal structure of radiation delivery, specifically the...
The E-320 experiment at SLAC FACET-II aims to investigate Quantum Electrodynamics (QED) in the strong-field regime.
By colliding 10 GeV, high-quality electron beams with 10 TW NIR laser pulses it is aspired to probe the QED critical (Schwinger) intensity of 10E29 Wcm-2 in the electron rest frame.
In this regime, characterized by X = E/Ecr>1, quantum corrections to classical synchrotron...
Laser-plasma electron acceleration hit a turning point by the recent demonstrations of plasma-wakefield-driven FEL. Yet, there are still the remaining challenges to be resolved before such compact light sources ready for user applications. We present recent progress made by the HZDR-SOLEIL collaboration in seeded FEL using the COXINEL FEL-line powered by the HZDR laser-plasma accelerator. This...
A long ion channel has been proposed as a possible way to reduce the bandwidth of betatron radiation emitted in a plasma due to its wakeless nature; this allows to exclude longitudinal momentum variations from the photon energy dispersion, only retaining the transverse oscillations as plasma induced energy spreads. Although the concept of ion channel laser was proposed back in the nineties, no...
We report on the development, commissioning, and the first light from RadiaBeam Inverse Compton Scattering (ICS) source. This ICS source is driven by the C-band hybrid photoinjector, and 100 MeV high gradient C-band linac. The first light at 200 keV photon energy was detected and characterized. The machine modular design allows for multiple future upgrades, including energy upgrade, as well...
The ion channel laser (ICL) is similar to the free electron laser (FEL) but utilizes the electric field from a blowout regime plasma wake rather than the magnetic field from an undulator to oscillate particles. Compared to the FEL, the ICL can lase with much larger energy spread beams and in much shorter distances, making it an attractive candidate for a future compact plasma accelerator...
At Eindhoven University of Technology, a tabletop x-ray source based on inverse Compton scattering (ICS) has recently been commissioned. In the ICS process monochromatic x-rays are produced by colliding relativistic electron bunches with intense laser pulses. This compact and tunable source holds the promise of a performance in between small-scale x-ray tubes and large-scale synchrotron light...
The BELLA Center at LBNL facilitates four independent laser-plasma accelerator systems and a high-repetition rate fiber laser laboratory, enabling a comprehensive research program spanning critical system development, early applications and collider-relevant studies. Recent advancements in ancillary components, including active stabilization systems and plasma sources, have enabled significant...
A laser-based neutron source was commissioned using the 1kHz repetition rate SYLOS3 laser of ELI-ALPS, delivering 80mJ, sub-10 fs laser pulses on a heavy water sheet. The accelerated deuterons induced a 2H + 2H fusion reaction on a rotating disk of deuterated polyethylene, resulting in neutrons with a mean kinetic energy of 3.5MeV in the forward direction. We maximized the neutron yield per...
Two-beam acceleration (TBA), pioneered at CERN, has witnessed breakthrough achievements over the last five years. Accelerating fields approaching 400 MV/m have been routinely produced experimentally. These achievements are bolstering efforts to explore the use of TBA to drive hard X-ray free-electron lasers based on future light source (FLS) concepts. As a first demonstration, a scaled-down...
All-optical high-energy X-ray (HEX) beam sources based on Inverse Compton Scattering (ICS) are a promising and innovative alternative to conventional sources, enabling the generation of X-ray beams with percent-level bandwidth. These X-rays are generated by colliding a laser pulse with relativistic electron beams from a laser-plasma accelerator. Although a low HEX bandwidth is essential for...
