The purpose of the HCAL is to stop and measure the energy of hadrons and prevent them from travelling further through the detector. Like the «ECAL», it is a sampling calorimeter made of layers of iron and plastic scintillator.
Software trigger. Software that decides if data from the detectore gets written to storage or thrown away. Trigger Studies for FCC are in its early stages and no implementations exist yet
HEP-wide benchmark for measuring CPU performance based on the SPEC2006 benchmark.
The HSF facilitates coordination and common efforts in HEP software and computing internationally.
