利物浦大学、巴塞罗那国家微电子中心（CNM）和瓦伦西亚原子研究所（IFIC）合作开发了一种用于光束测试的望远镜。该系统旨在在光束测试环境中使用不同类型的微带或像素硅探测器进行模拟电荷收集和空间分辨率测量。望远镜有四个XY测量以及触发平面（XYT板），它可以容纳多达12个设备在测试（DUT板）。DUT板使用两个甲虫专用集成电路用于读出冷冻硅探测器。电路板可以在自触发模式下运行。该板的特点是一个温度传感器，它可以安装在一个旋转舞台上。peltier元件用于冷却DUT。每个XYT板测量轨道空间点使用两个硅带探测器连接到两个甲虫asic。它也可以在光束测试中触发粒子轨迹。该板包括一个CPLD，可将触发信号同步到公共时钟频率，延迟并实现与其他XYT板的巧合。阿里巴巴母板用于读取和控制每个XYT/DUT板的公共触发信号和公共时钟信号。阿里巴巴董事会有一个TDC，可以记录每个触发的时间戳。每块阿里巴巴板收集的数据通过本地数据/地址总线按照定制的数字协议发送到一张主卡。主控板分配触发、时钟和复位信号。它还合并了多达16块阿里巴巴板的数据流。该板还有一个测试通道，用于在标准模式下测试XYT或DUT板。该板由Xilinx开发板和自定义补丁板实现。主控板与DAQ软件通过100M以太网连接。利用DAQ软件获得的数据，还开发了基于轨迹的准直软件。
A telescope for a beam test have been developed as a result of a collaboration among the University of Liverpool, Centro Nacional de Microelectronica (CNM) of Barcelona and Instituto de Fisica Corpuscular (IFIC) of Valencia. This system is intended to carry out both analogue charge collection and spatial resolution measurements with different types of microstrip or pixel silicon detectors in a beam test environment. The telescope has four XY measurement as well as trigger planes (XYT board) and it can accommodate up to twelve devices under test (DUT board). The DUT board uses two Beetle ASICs for the readout of chilled silicon detectors. The board could operate in a self-triggering mode. The board features a temperature sensor and it can be mounted on a rotary stage. A peltier element is used for cooling the DUT. Each XYT board measures the track space points using two silicon strip detectors connected to two Beetle ASICs. It can also trigger on the particle tracks in the beam test. The board includes a CPLD which allows for the synchronization of the trigger signal to a common clock frequency, delaying and implementing coincidence with other XYT boards. An Alibava mother board is used to read out and to control each XYT/DUT board from a common trigger signal and a common clock signal. The Alibava board has a TDC on board to have a time stamp of each trigger. The data collected by each Alibava board is sent to a master card by means of a local data/address bus following a custom digital protocol. The master board distributes the trigger, clock and reset signals. It also merges the data streams from up to sixteen Alibava boards. The board has also a test channel for testing in a standard mode a XYT or DUT board. This board is implemented with a Xilinx development board and a custom patch board. The master board is connected with the DAQ software via 100M Ethernet. Track based alignment software has also been developed for the data obtained with the DAQ software.
