To address the issue of long processing time in traditional offline position reconstruction methods, this paper proposes an FPGA-based online position reconstruction method, grounded in the micro time projection chamber principle. This method encapsulates key technical aspects: self-adaptive serial link technique built upon the dynamical adjustment of delay chain length, fast sorting and coordinate matching technique based on the mapping between signal timestamps and random access memory (RAM) addresses, and precise start point merging technique utilizing a circular combined RAM. The performance test of the self-adaptive serial link shows the bit error rate of the link is better than 10^-12 at a confidence level of 99%, ensuring reliable data transmission. The combined experiment of the readout electronics and the Micromegas detector shows a spatial resolution of approximately 1.4 mm, surpassing the current method's resolution level of 5 mm. The beam experiment confirms that the readout electronics system can obtain the flux spatial distribution of neutron beam online, thus validating the feasibility of the position reconstruction method. The online position reconstruction method avoids traditional methods such as bubble sorting and traversal searching, simplifying the design of logic firmware and reducing the time complexity from O(n^2) to O(n). This study contributes to the advancement in measuring neutron beam flux for BNCT. position reconstruction FPGA readout electronics neutron flux spatial distribution 来自： Jiang Wei 分类： 核科学技术 >> 核探测技术与核电子学 说明： 目前论文已投稿《Nuclear Science and Techniques》，并完成小修。 投稿状态： 正在评审中 引用： ChinaXiv:202311.00061 (或此版本 ChinaXiv:202311.00061V1 ) DOI:10.12074/202311.00061V1 CSTR:32003.36.ChinaXiv.202311.00061.V1 推荐引用方式： Wei Jiang ,Ping Cao ,Yi-Ming Wu, Xian-Ke Liu, Zhu-Jun Fang,Zhi-Yong Zhang,Bin Shi,Jun Chen.(2023).An FPGA-based position reconstruction method for neutron beam flux spatial distribution measurement in BNCT.中国科学院科技论文预发布平台.doi:10.12074/202311.00061V1 版本历史 [V3] 2024-02-07 12:33:39 ChinaXiv:202311.00061v3 查看此版本 下载全文 [V1] 2023-11-08 11:19:44 ChinaXiv:202311.00061V1 下载全文
