论文摘要
出色的粒子识别（PID）对于公平的熊猫实验至关重要。枪管DIRC将以至少3 s.d.分离kaons和pions。对于最大3.5 GEV/C和22至140度之间的极性角度。在成功验证了CERN PS/T9光束线中最终设计后，启动了两个最具时间和成本密集的物品的招标过程，即散热器栏和MCP-PMT。始于2018年。2019年9月，尼康被选中尼康（Nikon）以构建融合的硅棒，并成功地完成了Feb的112杆均可及其质量。在GSI上进行了评估。 2020年12月，预计将授予Photonis的MCP-PMTS制造合同，并预计将于2021年7月授予首次MCP-PMT。我们介绍了Panda Barrel Dirc的设计以及组件系列生产的状态以及质量评估的结果。
Excellent particle identification (PID) will be essential for the PANDA experiment at FAIR. The Barrel DIRC will separate kaons and pions with at least 3 s.d. for momenta up to 3.5 GeV/c and polar angles between 22 and 140 deg. After successful validation of the final design in the CERN PS/T9 beam line, the tendering process for the two most time- and cost-intensive items, radiator bars and MCP-PMTs, started in 2018. In Sep. 2019 Nikon was selected to build the fused silica bars and successfully completed the series production of 112 bars in Feb. 2021. Measurements of the mechanical quality of the bars were performed by Nikon and the optical quality was evaluated at GSI. In Dec. 2020, the contract for the fabrication of the MCP-PMTs was awarded to PHOTONIS and the delivery of the first-of-series MCP-PMTs is expected in July 2021. We present the design of the PANDA Barrel DIRC as well as the status of the component series production and the result of the quality assurance measurements.
