LHCb外跟踪器前端读出电子器件的生产和测试

Production and Testing of the LHCb Outer Tracker Front End Readout Electronics

Eduard Simioni

摘要:

LHCb外跟踪器是一种具有模块化设计的吸管漂移探测器,共有53760个读出通道分布在12个6x 5 m2的双层敏感区域。主要的电子读出要求是在4%的占有率和1 MHz读出时精确(0.5 ns)的漂移时间测量。一个前端盒总共可读取128个通道。大约一半的FE-Box已经建成。在生产过程中,对单个FE盒组件进行了质量保证。组装好的FE-Box最后使用特殊的FE-Tester进行调试。FE-Tester是一种可编程脉冲发生器,时间分辨率为150 ps,能够模拟模拟真实探测器的所有读出功能。因此,已经发现并解决了问题,从而产生了良好的总体性能。

英文摘要:

The LHCb Outer Tracker is a straw drift detector with a modular design and a total of 53760 readout channels distributed over a sensitive area of 12 double layers of 6x5 m2 each. The main electronics readout requirement is the precise (0.5 ns) drift time measurement at an occupancy of 4% and 1 MHz readout. A total of 128 channels are read out by one Front-End box. About half of the FE-Boxes have been built. Quality Assurance during the production has been performed on single FE-Box components. The assembled FE-Box is finally commissioned using a special FE-Tester. The FE-Tester is a programmable pulser with a time resolution of 150 ps capable to simulate all the functionality of the readout mimicking the real detector. Consequently, problems have been found and solved resulting in good overall performance.
