Laser-driven electron source suitable for single-shot Gy-scale irradiation of biological cells at dose-rates exceeding Gy/s
We report on the first systematic characterisation of a tuneable laser-driven
electron source capable of delivering Gy-scale doses in a duration of 10 - 20
ps, thus reaching unprecedented dose rates in the range of
Gy/s. Detailed characterisation of the source indicates, in agreement with
Monte-Carlo simulations, single-shot delivery of multi-Gy doses per pulse 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
ultra-high dose rates.Comment: submitted for publicatio
