The TRB3 features four FPGA-based TDCs with < 20 ps RMS time precision between two channels and 256+4+4 in total. One central FPGA provides flexible trigger functionality GbE connectivity including powerful slow control. We present recent users' applications of this platform following the COME&KISS principle: successful test beamtimes at CERN (CBM), Jülich Mainz an discriminator board (PaDiWa), a charge-to-width FEE high dynamic range, read-out n-XYTER ASIC software for data unpacking TDC...
The global polarization of {\Lambda} hyperons along the total orbital angular momentum a relativistic heavy-ion collision is presented based on high statistics data samples collected in Au+Au collisions at \sqrt{s_{NN}} = 2.4 GeV and Ag+Ag 2.55 with High-Acceptance Di-Electron Spectrometer (HADES) GSI, Darmstadt.

We present the first observation of K^{-} and ϕ absorption within nuclear matter by means π^{-}-induced reactions on C W targets at an incident beam momentum 1.7 GeV/c studied with HADES SIS18/GSI. The double ratio (K^{-}/K^{+})_{W}/(K^{-}/K^{+})_{C} is found to be 0.319±0.009(stat)_{-0.012}^{+0.014}(syst) indicating a larger in heavier as compared lighter ones. measured ϕ/K^{-} ratios π^{-}+C π^{-}+W acceptance are equal 0.55±0.04(stat)_{-0.07}^{+0.06}(syst)...
A feasibility study has been performed in order to investigate the performance of HADES detector measure electromagnetic decays hyperon resonances $\Sigma(1385)^0$, $\Lambda(1405)$ and $\Lambda{\Lambda}(1520)$ as well production double strange baryon systems $\Xi^-$ $\Lambda\Lambda$ p+p reactions at a beam kinetic energy 4.5 GeV. The existing will be upgraded by new Forward Detector, which extends acceptance into range polar angles that plays crucial role for these investigations. analysis...
High precision time measurements are a crucial element in particle identification experiments, which likewise require pulse width information for Time-over-Threshold (ToT) and charge (correlated with width). In almost all of the FPGA-based TDC applications, implemented using two channels leading trailing edge individually. This method however, requires twice number resources. this paper we present latest improvements high (8 ps RMS) developed before [1], as well novel way measuring ToT...
Pion-induced reactions provide unique opportunities for an unambiguous description of baryonic resonances and their coupling channels by means a partial-wave analysis. Using the secondary pion beam at SIS18, two-pion production in second resonance region has been investigated to unravel role $N(1520){\frac{3}{2}}^{\ensuremath{-}}$resonance intermediate $\ensuremath{\rho}$-meson production. Results on exclusive with one (${\ensuremath{\pi}}^{\ensuremath{-}}p$) two pions...

Motivated by the requirements of next generation experiments in terms very good time and position resolution high counting rate multiplicity environment, a new architecture differential, strip structure, symmetric, multi gap timing RPC was developed. The results on efficiency, resolution, performance environment using low resistivity glass electrodes are reported.
The HADES collaboration uses the e + − production as a probe of resonance matter produced in collisions at incident energies 1-3.5 GeV/nucleon GSI. Elementary reactions provide useful references for these studies and give information on Dalitz decays (R→Ne ). Such processes are sensitive to structure time-like electromagnetic baryon transitions kinematic range where (off-shell) vector mesons play crucial role. Results obtained proton-proton commissioning pion-beam experiment reported...
Abstract Low Gain Avalanche Detector (LGAD) technology has been used to design and construct prototypes of time-zero detector for experiments utilizing proton pion beams with High Acceptance Di-Electron Spectrometer (HADES) at GSI Darmstadt, Germany.
