标题： The OBDT-theta board: time digitization for the theta view of Drift Tubes chambers

摘要： 我们介绍了沿束流方向平行于超级层θ的漂移管（OBDT）的机载电子设备的设计和性能，这是新电路板，用于替换CMS DTμ子探测器电子设备的一部分。 OBDT-theta负责θ视图中漂移管室信号的时间数字化，从而实现对桶状μ子的进一步跟踪和触发。 它还负责θ视图中漂移管室内部电子设备的部分慢控制。 OBDT-theta电路板的原型正在CERN的不同实验室以及安装在CMS实验中的演示腔室中进行验证。 这允许在真实条件下评估电路板的全部功能，结果非常令人满意。 显示英文摘要

摘要： We present the design and performance of the On-Board electronics for the Drift Tubes (OBDT) for the superlayer theta along the direction parallel to the beam-line, the new board built to substitute part of the CMS DT Muon on-detector electronics. The OBDT-theta is responsible for the time digitization of the DT chamber signals for the theta view, allowing further tracking and triggering of the barrel muons. It is also in charge of part of the slow-control of the DT chamber inner electronics in the theta view. Prototypes of the OBDT-theta board are under validation in different laboratories in CERN, as well as in demonstrator chambers installed in the CMS experiment. This allows evaluation of the full functionality of the boards in real conditions, showing very satisfactory results.
