High-gradient low-β accelerating structure using the first negative spatial harmonic of the fundamental mode

Physical Review Accelerators and Beams, 2017
The development of high-gradient accelerating structures for low-β particles is the key for compact hadron linear accelerators. A particular example of such a machine is a hadron therapy linac, which is a promising alternative to cyclic machines ...

Transfer line scattering model of therapeutic hadron beams and applications to nozzle and gantry optimization

Physical Review Special Topics. Accelerators and Beams, 2013
The field of hadron therapy is growing rapidly with several facilities currently being planned, under construction or in commissioning worldwide. In the “active scanning” irradiation technique, the target is irradiated using a narrow pencil beam that is ...

Solution Radioactivated by Hadron Radiation Can Increase Sister Chromatid Exchanges.

PLoS ONE, 2015
When energetic particles irradiate matter, it becomes activated by nuclear reactions. Radioactivation induced cellular effects are not clearly understood, but it could be a part of bystander effects.

Towards Laser Driven Hadron Cancer Radiotherapy: A Review of Progress

Applied Sciences, 2014
It has been known for about sixty years that proton and heavy ion therapy is a very powerful radiation procedure for treating tumors. It has an innate ability to irradiate tumors with greater doses and spatial selectivity compared with electron and ...

Preliminary results of the Gas Electron Multiplier (GEM) as real-time beam monitor in hadron therapy

, 2017
The use of proton and carbon ion beams in cancer therapy (also known as hadron therapy) is progressively growing worldwide due to their improved dose distributions, sparing of healthy tissues and (for carbon ions) increased radiobiological effectiveness ...

Production of fast ion and nuclei bunches of solid densities from nanolayers by ultrarelativistic laser pulses

Physical Review Special Topics. Accelerators and Beams, 2011
A method for generation of quasimonoenergetic, low emittance fast ion/nuclei bunches of solid densities from nanotargets by two counterpropagating laser pulses of ultrarelativistic intensities is proposed, based on the threshold phenomenon of particles ...
