Abstract

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 at the Reactions with Relativistic Radioactive Beams (R³B) facility of GSI-FAIR. 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 R³B. In this paper, we describe the design of the detector and provide the results of its first characterizations.
