4.2 Particle Acceleration with Laser and Beams

Oral

The FLASHForward experiment at DESY is a beam line build for beam-driven plasma-wakefield acceleration. The drive beams, supplied by the linac of the free-electron laser FLASH, have energies of up to 1.25GeV, a typical charge of 400 pC, emittance of a few mm mrad and a pulse duration down to 50fs. The extensive experimental programme consists of various experiments among which three are...

4.2 Particle Acceleration with Laser and Beams

Oral

The future (and potential limitations) of compact particle accelerator technology depends on the ability to characterize and manipulate the conditions in plasma discharge devices, such as plasma targets and active plasma lenses (APLs).

For many high energy physics applications and novel radiation sources, high repetition rates are required. For example, the FLASHForward [1] experiment at...

4.2 Particle Acceleration with Laser and Beams

Oral

The Advanced Wakefiled Experiment (AWAKE) at CERN is a proof-of-principle experiment for the concept of a proton-driven plasma-wakefield accelerator. In AWAKE, electrons are externally injected in wakefields driven by the 400$\,$GeV proton beam of the Super Proton Synchrotron (SPS) and accelerated over 10 meters of plasma up to energies in the GeV range.
We have shown that in plasma the...

4.2 Particle Acceleration with Laser and Beams

Oral

The study was evaluated on a hydrogen Z-pinch plasma guiding channel generated by a fast discharge in a capillary with diameter of 3 mm and length of 50 mm. By using the 1D MHD model a radial distribution of the electron density profile was computed which capable for guiding the high intensity TEM$_{00}$ mode CO$_2$ laser pulse with input spot size of 150 $\mu$m and peak intensity of 10$^{18}$...

4.2 Particle Acceleration with Laser and Beams

Oral

Laser proton accelerator has been considered as one promising candidate for the future compact and low-cost radiotherapy system for malignant tumors. A Compact LAser Plasma Accelerator (CLAPA) has been built at Peking University, which can reliably generate and transport MeV energy protons with designed charge, spot and energy spread on to the irradiation platform. The transverse geometric...
