Czech scintillation detectors based on PbWO4 crystals are already in Darmstadt

Unique scintillation PbWO₄ detectors for the Electromagnetic Calorimeter (ECAL), intended for the scientific pillar PANDA, were delivered this year by the Czech team of the FAIR-CZ-OPII project to the international FAIR laboratory in Darmstadt.

Colleagues from the Faculty of Mathematics and Physics of Charles University in Prague, in cooperation with the NPI´s Microtron Laboratory team, delivered a pilot series of unique detectors based on PbWO₄ crystals, manufactured at CRYTUR Turnov company, to Germany as part of the development of gamma radiation detectors for ECAL in the PANDA experiment. In the period 2022-2023, they delivered the last 52 pieces, a total of 323 pieces of crystals were delivered.

The supply of PbWO₄ crystals is an in-kind contribution of the Czech Republic as an associate member of FAIR to the PANDA pillar.
