摘要

<正>Heavy ions have a favorable depth-dose profile (Bragg curve) and the narrow Bragg peak can be precisely adjusted to the desired depth by changing the beam energy. The ions as heavy as or heavier than carbon can additionally offer an enhanced biological efficiency in the region around Bragg peak because of the very dense ionization towards the end of the particle tracks. Several heavy ions therapy facilities have been
