摘要

我们首次报道了一种可调激光驱动电子源的系统特性，这种电子源能够在 10-20 ps 的持续时间内提供 Gy 级剂量，从而达到前所未有的 1010-1012 Gy/s 剂量率。该源的详细特性表明，与蒙特卡洛模拟一致，在厘米级区域内的剂量传输具有高度的空间均匀性。本文报告的结果证实，这种激光驱动源可用于系统研究生物细胞对皮秒级超高剂量率辐射的反应。

Laser-driven electron source suitable for single-shot Gy-scale irradiation of biological cells at dose rates exceeding 1010 Gy/s

We report on the first systematic characterization of a tuneable laser-driven electron source capable of delivering Gy-scale doses in a duration of 10–20 ps in a single irradiation, thus reaching unprecedented dose rates in the range of

10^{10} – 10^{12}

Gy/s. Detailed characterization of the source indicates, in agreement with Monte Carlo simulations, dose delivery over cm-scale areas with a high degree of spatial uniformity. The results reported here confirm that a laser-driven source of this kind can be used for systematic studies of the response of biological cells to picosecond-scale radiation at ultrahigh dose rates.
