已经建造和测试了作为ALICE探测器一部分的PHOS电磁分光计的大型原型。该原型有256个探测器通道，在-25摄氏度下工作。每个探测器通道是一个钨酸铅晶体耦合到雪崩光电二极管与低噪声放大器。该原型包括一个16 × 16的晶体矩阵，光电探测器，模拟和数字电子，热稳定冷却系统，发光二极管监测系统和带电粒子探测器作为否决计数器。使用电子和强子束的欧洲核子研究中心PS和SPS加速器的测量结果进行了讨论，原型的性能进行了评估。(c)2005 Elsevier B. V.保留所有权利。
A large-scale prototype of the PHOS electromagnetic spectrometer, which is part of the ALICE detector, has been built and tested. This prototype has 256 detector channels and is operated at -25 degrees C. Each detector channel is a lead-tungstate crystal coupled to an Avalanche Photo-Diode with a low-noise preamplifier. The prototype includes a 16 x 16 crystal matrix, photo-detectors, analog and digital electronics, a thermo-stabilized cooling system, a light-emitting diode monitoring system, and a charged-particle detector acting as veto counter. Results of measurements using electron and hadron beams of the CERN PS and SPS accelerators are discussed, and the performance of the prototype is evaluated. (c) 2005 Elsevier B.V.
