P-bar ANDA（达姆施塔特反质子化）实验的强大粒子识别探测系统包含三个切伦科夫探测器。在前向方向上，规划了常规的RICH检测器。在目标光谱仪的高螺线管场中，使用DIRC原理的薄切伦科夫探测器是强制性的，并且设想为桶和垂直盘的形式。光子的到达时间与其空间图像的组合不仅决定了粒子的速度，而且还决定了光子的波长。因此，可以对下检测阈值和上检测阈值进行色散校正。调查有关的发展三维桶DIRC进行了讨论，以及两个不同的研究实现了一个新的光盘DIRC的前角。一种是基于传播时间（ToP）的方法，另一种是基于聚焦光导的读出。
The powerful particle identification detection system of the P-bar ANDA (antiProton ANihilations at DArmstadt) experiment contains three Cherenkov detectors. In the forward direction a conventional RICH detector is planned. In the high solenoid field of the target spectrometer thin Cherenkov detectors using the DIRC principle are mandatory and are envisaged in the form of a barrel and a vertical disc. The combination of the time of arrival of the photons with their spatial image determines not only the particle velocity, but also the wavelength of the photons. Therefore dispersion corrections on the lower and upper detection threshold is possible. Investigations concerning the development of a 3D-Barrel-DIRC are discussed as well as two different studies realizing a new Disc-DIRC for the forward angles. One is based on the Time of Propagation (ToP) method the other on the readout with focusing light guides.
