750 MHz radio frequency quadrupole with trapezoidal vanes for carbon ion therapy

Physical Review Accelerators and Beams, 2020
High-frequency linear accelerators are very suitable for carbon ion therapy, thanks to the reduced operational costs and the high beam quality with respect to synchrotrons, which are presently the only available technology for this application.

Quasi-monoenergetic carbon ions generation from a double-layer target driven by extreme laser pulses

New Journal of Physics, 2023
High quality energetic carbon ions produced via laser-plasma have many applications in tumor therapy, fast ignition and warm dense matter generation. However, the beam achieved in current experiments is still limited by either a large energy spread or a ...

Carbon-ion Radiotherapy for Colorectal Cancer

Journal of the Anus, Rectum and Colon, 2021
Heavy-ion radiotherapy (RT) is a kind of particle RT, and carbon-ion beam constitutes the primary delivery method of heavy-ion RT. Unlike the conventional photon modalities, particle RT, in particular carbon-ion radiotherapy (CIRT), offers unique ...
