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.

在这一年中，我使用了基于闪烁器的横向质子束剖面仪（PBP）诊断，在超高强度激光驱动的离子加速实验使用J-KAREN-P设施在过去几年中开发的。 PBP是激光离子源的关键诊断，首次以高重复率测量了>10 MeV的激光加速质子。 我们使用它来执行详细的参数扫描，从而优化质子束流，目前正在准备发表。描述PBP的同行评审论文于2017年7月发表在《科学仪器评论》上，使用了上一财年的数据。 PBP的数据和分析在各种国际会议上发表，包括横滨OPIC 2018和意大利EAAC 2018。
