CALICE Digital Hadron Calorimeter: Calibration and Response to Hadrons
Abstract
The large CALICE Digital Hadron Calorimeter prototype (DHCAL) was built in 2009 - 2010. The DHCAL uses Resistive Plate Chambers (RPCs) as active media and is read out with 1 x 1 cm2 pads and digital (1 - bit) resolution. With a world record of about 0.5M readout channels, the DHCAL offers the possibility to study hadronic interactions with unprecedented spatial resolution. This talk reports on the results from the analysis of pion events of momenta between 2 to 60 GeV/c collected in the Fermilab test beam with an emphasis on the intricate calibration procedures.
