The PANDA forward endcap calorimeter arrived in Bonn to be used as forward calorimeter of the new INSIGHT-experiment at ELSA

After many years of R&D and in close collaboration with groups from other universities, the Bonn group has started to build-up the forward endcap calorimeter (FWEC) of the PANDA-experiment at the research center Jülich in 2023. After at first very successful test beam time at the COSY accellerator with a partly equipped detector system - 20% of the almost 3856 PbWO₄-crystals were installed - at its design temperature of -25°C, the detector system was transported to Bonn. At the FTD, the forward endcap will be equipped with all its crystals, closing also its inner hole before it will then be installed at ELSA to be used as forward calorimeter in the new INSIGHT-experiment.

On August 20th, 2024 the detector arrived at the FTD, using heavy load transportation since the detector already now weigths about 4 tons. After it was slowly and carefully moved into the assembly hall, the detector is now ready for further installation of the remaining detector modules.
