位于达姆施塔特的FAIR升级为GSI的PANDA实验旨在以前所未有的精度研究现代强子物理。对带电粒子和中性粒子的良好识别是实现PANDA物理目标的必要条件。两个DIRC探测器预计带电粒子识别，一个在桶配置的中心区域，第二个在一个磁盘配置的前端盖。前向盘DIRC的设计围绕着无源色散校正元件的新颖应用，与聚焦光学器件相结合，以实现Chernekov角的出色分辨率。系统的综合原型开发将显示系统的可行性。原型成功的关键是充分理解探测器内切伦科夫光子的产生、传输和探测。测量了光子产额及其与探测器极角的关系。观测到的光子产额也是随后研究色散校正元件、聚焦和整体探测器性能的基础。
The PANDA experiment at the FAIR upgrade to GSI, Darmstadt, aims to study modern hadronic physics with unprecedented precision. Excellent particle identification of both charged and neutral particles is necessary to achieve the physics aims of PANDA. Two DIRC detectors are foreseen for charged particle identification, one in a barrel configuration for the central region, and the second in a disc configuration for the forward endcap. The design of the forward disc DIRC centres around the novel application of passive chromatic dispersion correction elements, allied with focussing optics, to achieve excellent resolution of Chernekov angle. A system of comprehensive prototype development will show the feasibility of the system. Key to the success of the prototype is fully understanding the production, transport and detection of the Cherenkov photons within the detector. Photon yield and its dependence on the polar angle of the detector have been measured. Observed photon yield is also the basis for subsequent studies into the benefit of chromatic dispersion correction elements, focussing and overall detector performance.
