AI中文摘要：
人工产生的μ子束，具有可调参数，在成像那些对其他任何扫描技术都不透明的物体方面极具价值。目前，较低能量的μ子束在加速器设施中产生，而较高能量的μ子束仅在近期才通过激光尾场加速电子与固体靶相互作用而被观测到。本工作重点在于利用μ子成像探测器测量通过Bethe-Heitler过程产生的μ子束的轮廓，并在延伸至距μ子源42米的实验装置中进行μ子成像。通过将数据与蒙特卡洛模拟进行比较，我们确认所测得的束流轮廓和物体成像与能量为几个GeV的人工产生的μ子一致。据我们所知，这代表了首次演示由人工激光驱动μ子束主导的成像。
英文摘要：
Artificially generated muon beams, with tunable parameters, are highly valuable in imaging objects that are opaque to any other scanning technique. Lower-energy muon beams are currently produced at accelerator facilities, while higher energies have only recently been observed as a result of the interaction of laser-wakefield-accelerated electrons and solid targets. This work focuses on using muography imaging detectors to measure the profile of a muon beam generated via the Bethe-Heitler process and to perform muon imaging in an experimental setup extending up to 42 meters from the muon source. By comparing the data with Monte Carlo simulations, we confirm that the measured beam profile and object imaging are consistent with artificially produced muons of energy of a few GeV. To our knowledge, this represents the first demonstration of imaging dominated by an artificial, laser-driven muon beam.
