During this year, I used the scintillator-based transverse proton beam profiler (PBP) diagnostic developed over the previous years on ultra-high intensity laser-driven ion acceleration experiments using the J-KAREN-P facility. The PBP was a key diagnostic of the laser ion source, measuring, for the first time, laser-accelerated protons >10 MeV at high repetition rate. We used this to perform detailed parameter scans, allowing optimisation of proton beam flux, currently being prepared for publication.A peer-reviewed paper describing the PBP was published in Review of Scientific Instruments in July 2017, using data from the previous FY. Data and analysis from the PBP was presented at various international conferences, including OPIC 2018 in Yokohama and EAAC 2018 in Italy.

在今年，我使用了使用J-Karen-P设施的超高强度激光驱动的离子加速度实验，使用了前几年开发的基于闪烁剂的横向质子束探测器（PBP）诊断。 PBP是激光离子源的关键诊断，首次以高重复速率测量激光加速质子> 10 MeV。 我们用它进行了详细的参数扫描，允许优化质子束通量，目前正在准备出版。由同行评审的论文描述了PBP，该论文使用上一fy的数据发表在2017年7月的Scientific Instruments评论中。 PBP的数据和分析在各种国际会议上介绍，包括横滨的OPIC 2018和意大利的EAAC 2018。
