A DIELECTRIC-BASED, GeV/m CROSSED-LASER-BEAM ELECTRON LINEAR ACCELERATOR*
The acceleration gradient of a conventional RF accelerator is limited to about 50 MeV/m. To generate TeV electrons for next generation high energy physics, an RF accelerator would require a distance exceeding 20 km. In this paper, we propose a dielectric-based, multistaged, laser-driven electron linear accelerator operating in a vacuum that is capable of providing 1 TeV electrons in 1 km. Our s...
متن کاملProposed structure for a crossed-laser beam, GeV per meter gradient, vacuum electron linear accelerator
We propose a dielectric-based, multistaged, laser-driven electron linear accelerator structure operating in a vacuum that is capable of accelerating electrons to 1 TeV in 1 km. Our study shows that a GeV/m gradient is achievable using two 100 fs focused crossed-laser beams, repeated every 300 mm, operated at a peak power of 0.2 GW and an energy density of less than 2 J/cm on the accelerator str...
متن کاملGeV electron beams from a centimeter-scale channel guided laser wakefield accelerator
Laser wakefield accelerators can produce electric fields of order 10–100 GV/m, suitable for acceleration of electrons to relativistic energies. The wakefields are excited by a relativistically intense laser pulse propagating through a plasma and have a phase velocity determined by the group velocity of the light pulse. Two important effects that can limit the acceleration distance and hence the...
متن کاملA Monte Carlo study on Photoneutron Spectrum around Elekta SL75/25 18 MV linear accelerator
Medical linear accelerators are one of the most widespread methods for cancer treatment. Despite their advantages, unwanted photoneutrons are produced by high energy linacs. This photoneutrons are as undesired doses to patients and a significant problem for radiation protection of the staffs and patients. Photoneutrons radiological risk must be evaluated because of their high LET and range.in o...
