HYDRA: HYpernuclei Decay at R3B Apparatus — •Simone Velardita, Liancheng Ji, Alexandre Obertelli, and Yelei Sun for the R3B collaboration — Technische Universität Darmstadt
HYDRA is a physics program within the R3B collaboration at the decay spectroscopy of hypernuclei produced from heavy-ion collisions at GSI/FAIR. The program aims at measuring with high resolution the in-flight pionic decay of light and medium mass hypernuclei. The pion tracker is conceived as a time projection chamber inside the GLAD magnet of the R3B setup.
As a first step, a prototype TPC was built to implement all the technologies proposed for the full TPC. The prototype covers an active area of 256 x 88 mm2 decomposed into 5632 pads. In the drift region in which the drift length is 300 mm, a homogeneous electric field is held up by a two-layer wire field cage. A compact metal-core Micromegas pad plane is used to amplify and collect drift electrons. The prototype was tested at TU Darmstadt. The first results will be presented in the poster.
The full experimental setup has been simulated within the R3BROOT framework. Simulations were used to optimise the geometry and to define conditions for a forthcoming experiment at GSI/FAIR. Results will be detailed. The first experiment to be proposed with the HYDRA prototype, aiming at the mass radius of hypernuclei such as the hypertriton, expected to be halo, from interaction cross section measurement will be detailed in the poster.
