标题： The HYDRA pion-tracker for hypernuclei studies at R3B

摘要： HYpernuclei-Decay at R3B Apparatus (HYDRA)跟踪器是一种新型的时间投影室，结合了塑料闪烁体墙用于时间测量和触发目的。 该探测器是一个低辐射长度的跟踪器，专门用于测量在GSI-FAIR的R3B实验中，由几GeV/核子的离子-离子碰撞产生的轻超核弱衰变中的π介子，这些实验是在大型接受度二极磁铁GLAD的磁场中进行的。 在本文中，我们描述了该探测器的设计，并提供了其首次特性化结果。 显示英文摘要

摘要： The HYpernuclei-Decay at R3B Apparatus (HYDRA) tracker is a novel time projection chamber combined with a plastic scintillator wall for timing and trigger purposes. This detector is a low radiation length tracker dedicated to measuring pions from the weak decay of light hypernuclei produced from ion-ion collisions at few GeV/nucleon in the magnetic field of the large-acceptance dipole magnet GLAD at the Reactions with Relativistic Radioactive Beams (R3B) experiment at GSI-FAIR. In this paper, we describe the design of the detector and provide the results of its first characterizations.
