"Deep-seated tumors can be efficiently treated with heavy charged particles. The characteristic\r\ndepth dose profile inside the tissue (Bragg peak) allows to deliver\r\na high dose inside the tumor, while sparing the neighboring healthy tissue.\r\nAs compared to protons, heavy ions like carbon or oxygen produce a higher\r\namount of ionization events along their track (and in particular at the end\r\nof the ion beam path), resulting in an irreparable damage to the DNA of the\r\ntumor cells. The density of such ionization events is described in terms of\r\nLinear Energy Transfer (LET), an important physical quantity, but difficult\r\nto be measured directly. The aim of this work is to determine LET of hadrontherapy\r\nbeams by using Liquid Ionization Chambers (LIC). The ionization\r\nsignal in LICs is affected by recombination effects that depend on the LET\r\nof the incident radiation. Differences in recombination effects in LICs and\r\nair-filled ionization chambers can be exploited to obtain the recombination\r\nindex, which can be related to the LET, calculated by Monte Carlo methods.\r\nWe thus developed a method to construct a calibration curve, which relates\r\nthe recombination index with the LET at each depth in water. The result of\r\nthis work can be used for online monitoring of the ion beam quality."^^ . "2013" . . . . . . . "Sara"^^ . "Tegami"^^ . "Sara Tegami"^^ . . . . . .
