摘要

DAMON（直接测量目标碎裂）项目旨在探索使用纳米成像跟踪器（NIT）首次直接测量质子束在癌症治疗中造成的目标碎裂。NITs 是一种细粒度的核乳剂薄膜，具有纳米级的空间分辨率。DAMON 的试验性测试将基于 NIT 的探测器暴露于 211 MeV 质子，为首次研究直接运动学中的靶碎裂铺平了道路。本文报告了有关碎片数量及其轨迹长度的初步结果。

From dark matter searches to proton therapy: Measuring target fragmentation with nanometric nuclear emulsions

The DAMON (Direct meAsureMent of target fragmentatiON) project aims to explore the use of Nano Imaging Trackers (NITs) for the first direct measurement of target fragmentation caused by proton beams in cancer treatment. NITs are fine-grained nuclear emulsion films that offer a spatial resolution at the nanometric scale. DAMON’s pilot test exposed a NIT-based detector to 211 MeV protons, paving the way for the first study of target fragmentation in direct kinematics. In this paper the preliminary results regarding the multiplicity of the fragments and their track lengths are reported.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
