Correlation between the total observed ionization energy and the electromagnetic component of the shower, as measured by the Cherenkov component. The calibration factor K is determined by the requirement that K×ECherenkov = Eionization for electrons.
The CCAL02 detector
Is an implementation of a daul read-out, total absorption crystal calorimeter made of BGO crystals. CCAL02 is based on the SID02 geometry but the space currently occupied by ECAL/HCAL Barrel/Endcap is replaced by the Crystal calorimeter. All other detectors (tracking etc.) as they are. ECAL deep enough to contain most EM showers.
