在未来的反质子和离子研究设施（FAIR）中进行的潘达实验旨在研究与1- 15 GeV/c范围内的反质子的强相互作用。对于带电粒子的识别，特别是K介子，人们预见到两个DIRC探测器。这些将位于PÁNDA的目标光谱仪部分。带有条形散热器的桶形DIRC将覆盖中心区域，圆盘DIRC将位于前端盖部分。对于后者，两个读出的概念进行了研究：测量光子的传播时间在多波段光盘DIRC，或测量角度的聚焦光导色散校正光盘DIRC。
The P¯ANDA experiment at the future Facility for Anti-proton and Ion Research (FAIR) aims at studying the strong interaction with antiprotons in the 1–15GeV/c range. For the charged particle identification, in particular of kaons, one foresees two DIRC detectors. These will be located in the target spectrometer section of P¯ANDA. A barrel shape DIRC with bar radiators will cover the central region, and a disc DIRC will be located in the forward endcap part. For the latter, two readout concepts are investigated: measuring the photon time-of-propagation in a multi-wavelength band disc DIRC, or measuring angles in a focussing lightguide dispersion-correcting disc DIRC.
