ALICE (A Large Ion Collider Experiment) is one of the four major experiments at the LHC (Large Hadron Collider), CERN. It is dedicated to the study of ultra-relativistic heavy-ion collisions. It has been designed to measure, in the most complete way possible, the particles produced in the collisions, so that the evolution of the system in space and time can be reconstructed and studied. The ALICE Time-Projection Chamber (TPC) is the main device, in the ALICE "central barrel", for tracking of charged particles and particle identification. The ALICE TPC is the largest detector of this type in the world and was designed to cope with the highest conceivable charged particle multiplicities. The collisions, which are detected with the TPC, occur approximately 200 times per second and in each collision about 4000 - 12000 charged particles are created

HADES at GSI (Darmstadt)

DarmHADES (High Acceptance DiElectron Spectrometer) is a versatile detector for a precise spectroscopy of e+e- pairs (dielectrons) and charged hadrons produced in proton, pion and heavy ion induced reactions in a 1-3.5 GeV kinetic beam energy region. The detector has been set-up at GSI by an international collaboration of 17 institutions from 9 European countries. The main experimental goal is to investigate properties of dense nuclear matter created in the course of heavy ion collisions and ultimately learn about in-medium hadron properties (like masses, decay widths). The matter created in such collisions differs from the one studied at SPS, RHIC or LHC because it consists mainly of baryons (nucleons and its excited states- baryon resonances) and little mesons and can be compressed up to 3 times nuclear matter density for about 10-12 fm/c. Dielectron pairs originating from in-medium hadron decays and rare strange hadrons (kaons, hyperons) are the main probes measured in the experiment. Since conclusions on in-medium effects rely strongly on the understanding of hadron properties in vacuum and their production mechanism in nucleon-nucleon collisions a complementary program focusing on e+e-, kaon and hyperon (Σ, Λ) production in elementary collisions is also in progress.

AMADEUS at DAΦNE (Frascati)

The AMADEUS collaboration  makes use of the data collected with by the KLOE collaboration  to investigate the behaviour of strange matter in the nuclear enviroment by studying the absorption of slow Kaons in light nuclei. The DAΦNE e+ e - collider delivers low energy back-to-back kaons with momentum range of 90-130 MeV/c stemming from the decay of φ mesons produced at rest, The KLOE spectrometer, located at one of the DAΦNE interaction points, consists of the world biggest Drift Chamber, surrounded by an Electromagnetic Calorimeter (EMC) providing a solid angle coverage of 98%
