HADES is taking data again, after the stop for accelerator improvements
"The accelerator infrastructure at GSI was shutdown for upgrading during last five years and resumed in middle of 2018. The also renovated HADES spectrometer is now back in operation."
The LIP-HADES group was originally created for the design and construction of a Time of Flight (TOF) detector based on Resistive Plate Chambers (RPCs), RPC-TOF-Wall (RPC-TOF-W), for the HADES spectrometer, operated at GSI, Darmstad, Germany. In recent years, the group was complemented with the incorporation of people from the LIP-COMPASS group who assumed tasks on the physics analysis. Currently the group has assumed new commitments with the construction of a new TOF detector for the HADES forward region, the RPC-TOF-FD, and reinforced our position in the collaboration by collaborating with the Multi Drift Chamber (MDC) group.
The accelerator infrastructure at GSI was shutdown for upgrading during last five years and resumed in middle of 2018. The also renovated HADES spectrometer (new electromagnetic calorimeter (ECAL) and RICH detector, with the consequent full remounting of the RPC-TOF-wall) is now back in operation. The realized upgrades will put into operation the future SIS100 synchrotron at the new FAIR facility, providing higher beam energies and intensities. HADES will be one of the first experiments to be operational at FAIR with the mission of providing high-quality dilepton data at baryon densities and temperatures not accessible by other detectors, neither in the past nor in the foreseeable future.
