A feasibility study has been performed in order to investigate the performance of the HADES detector to measure the electromagnetic decays of the hyperon resonances $$\Sigma (1385)^{0}$$ Σ ( 1385 ) 0 , $$\Lambda (1405)$$ Λ ( 1405 ) and $$\Lambda (1520)$$ Λ ( 1520 ) as well as the production of double strange baryon systems $$\Xi ^{-}$$ Ξ - and $$\Lambda $$ Λ $$\Lambda $$ Λ in p + p reactions at a beam kinetic energy of $$4.5\,{\mathrm{GeV}}$$ 4.5 GeV . The existing HADES detector will be upgraded by a new Forward Detector, which extends the detector acceptance into a range of polar angles that plays a crucial role for these investigations. The analysis of each channel is preceded by a consideration of the production cross-sections. Afterwards the expected signal count rates using a target consisting of either liquid hydrogen or polyethylene are summarized.

“…In FAIRRoot, a ROOT based code, the user can create simulated data and perform analysis within the same framework. Moreover, Geant3 and Geant4 [3] transport engines are supported; however, the user code that creates simulated data does not depend on a particular Monte Carlo engine. The framework delivers base classes which enable the users to construct their detectors and analysis tasks in a simple way.…”

In order to deepen the understanding of the properties of cosmic rays arriving to the Earth, a new generation high granularity and high time resolution cosmic ray tracking detector, TRAGALD-ABAS, based on timing RPC cells, has been recently installed at the Faculty of Physics of the Univ. of Santiago de Compostela, in Spain. At the same time a broad multidisciplinary collaboration, with researchers of several European countries, has been organized for both the maintenance and the improvement of the facility and for the analysis of the data. The detector is taking data with three active planes since March. 2015 at an approximate rate of 80 Hz. In this article, some of the performances and technical aspects of the detector areas are commented and some preliminary results related with several of the accessible research are discussed.

Performances of 4-gap timing RPCs for relativistic ions in the rangeZ= 1–6

et al. 2009

We present the performance of Multi-gap timing RPCs under irradiation by fully stripped relativistic ions (γβ =2.7, Z=1-6). A time resolution of 80 ps at high efficiency has been obtained by just using standard 'off the shelf' 4-gap timing RPCs from the new HADES ToF wall. The resolution worsened to 100 ps for ∼ 1 kHz/cm 2 proton flux and for ∼ 100 Hz/cm 2 Carbon flux. The chambers were operated at a standard field of E = 100 kV/cm and showed a high stability during the experiment, supporting the fact that RPCs are a convenient choice when accommodating a very broad range of ionizing particles is needed. The data provides insight in the region of very highly ionizing particles (up to ×36 mips) and can be used to constrain the existing avalanche and Space-Charge models far from the usual 'mip valley'. The implications of these results for the general case of detection based on secondary processes (n, γ) resulting in highly ionizing particles with characteristic energy distributions will be discussed, together with the nature of the time-charge correlation curve.
