H

HCAL: Hadronic Calorimeter

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.

HEPPY

Software framework for analyses in High Energy Physics, implemented in python.

HLT: High Level Trigger

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

HOM: Higher Order Modes

HS06

HEP-wide benchmark for measuring CPU performance based on the SPEC2006 benchmark.

HSF: HEP Software Foundation

The HSF facilitates coordination and common efforts in HEP software and computing internationally.
