HYDRA (HYpernuclei Decay at R3B Apparatus), a physics program within the R3B collaboration at GSI/FAIR, is dedicated to studying the production of light and medium mass hypernuclei in ion-ion collisions by measuring their pionic decay. With HYDRA day-one experiment in 2024 the mass radius of the hypertriton, the lightest hypernucleus will be extracted for the first time. The main tracking detector, a time projection chamber (TPC) is being developed and will be operated inside an inhomogeneous magnetic field of the GLAD large-acceptance dipole magnet at the R3B setup.
As the first step, a prototype GEM-Micromegas hybrid TPC has been built to implement all the technologies proposed for the full TPC. It covers an active area of 256 x 88 mm2 , with a 300 mm drift distance. A two-layer wired field cage holds up the electric field. Along with it, a laser system is employed to generate reference tracks with which the homogeneity of the drift field can be quantified and calibrated.
Currently the prototype is being tested at TU Darmstadt. Simulations and first test results will be presented in the poster.
