MicroBooNE

MicroBooNE实验是一种新型中微子探测器，将于2015年在费米实验室（芝加哥附近）运行。它由一个大体积（大约双层公共汽车的大小）组成，充满了-189摄氏度的液态氩。一束强烈的中微子从费米实验室的加速器复合体射向470米外的探测器。中微子是“幽灵粒子”，几乎不与物质相互作用，大多数只会通过MicroBooNE探测器和地壳。然而，光束足够强烈，大约三年内，探测器中将有几十万个相互作用。MicroBooNE液氩技术能够以亚毫米的精度对相互作用进行三维拍摄。该提案的重点是开发先进的重建软件，将记录的MicroBooNE数据转换为中微子相互作用中产生的粒子的三维图像。

The MicroBooNE experiment is a new type of neutrino detector that will operate at Fermilab (near Chicago) from 2015. It consists of a large volume (about the size of a double-decker bus) filled with liquid argon at -189 degrees Celsius. An intense beam of neutrinos is fired 470 m towards the detector from the Fermilab accelerator complex. Neutrinos are "ghost particles" that barely interact with matter and most will simply pass through the MicroBooNE detector and Earth's crust. However, the beam is sufficiently intense that a few 100,000 will interact in the detector in approximately three years. The MicroBooNE liquid argon technology enables the interactions to be photographed in three dimensions with sub-mm precision. This proposal focusses on the development of advanced reconstruction software to turn the recorded MicroBooNE data into three-dimensional images of the particles produced in the neutrino interactions.
