Forward calorimeter of ZEUS detector HCAL calibration using halo muons Forward calorimeter of ZEUS detector μ+ 30GeV 920GeV Total energy distribution of halomuons in FCAL and RCAL (solid line), in comparison with halomuon energy distribution in FCAL (dash line) Muons μ+ moving in straight trajectory from rear to front part of ZEUS calorimeter. Accelerated protons interacted with rest gas to produce π+ that decayed into μ+
