10 Feb 2017 | | Abstract: | Comparing with conventional accelerator, laser plasma accelerator can
generate high energy ions in a greatly reduced scale due to its TV/m
acceleration gradient. A compact laser plasma accelerator (CLAPA) has been
built at Institute of Heavy Ion physics in Peking University, based on which
application researches like biological irradiation, astrophysics simulation
etc. will be carried on. A beamline system with multi group of quadrupoles and
analyzing magnet for laser accelerated ions is proposed here. Since laser
accelerated ion beams have broad energy spectrum and large angular divergence,
the parameters (beam waist position in Y direction, beam line layout, drift
distance, magnet angles etc.) of the beamline system is carefully designed and
optimised to obtain a radially symmetric proton distribution at the irradiation
platform. Requirement of energy selection and differences in focusing or
defocusing in application system have great influence on evolution of proton
distribution. With optimal parameters, radially symmetric proton distribution
can be realized and protons with different energies have similar transverse
areas at experiment target. | | Source: | arXiv, 1702.3091 | | Services: | Forum | Review | PDF | Favorites | |
