在1-15GeV/c的能量范围内，具有前所未有强度的冷却反质子束将在广交会上用于P‘ANDA实验，以在迷人的夸克部分进行高精度的实验。筒状区域的带电粒子识别需要一个工作在强磁场中的薄探测器。使用DIRC原理的切伦科夫探测器可以满足这两个要求。将光子到达的时间与其空间图像相结合，不仅可以确定粒子的速度，还可以确定光子的波长。因此，可以在检测阈值的下限和上限进行色散校正。必须特别注意将光子探测器连接到筒状散热器棒上。
Cooled antiproton beams of unprecedented intensities in the energy range of 1–15GeV/c will be used at the P¯ANDA experiment at FAIR to perform high precision experiments in the charmed quark sector. The charged particle identification in the barrel region needs a thin detector operating in a strong magnetic field. Both requirements can be met by a Cherenkov detector using the DIRC principle. Combining the time of arrival of the photons with their spatial image determines not only the particles velocity, but also the wavelength of the photons. Therefore, dispersion correction at the lower and upper detection thresholds is possible. Special care has to be taken to couple the photon detector to the barrel radiator bars.
