Di-jet Calorimeter

  • Posted on: 7 April 2015
The DCal will extend significantly the jet quenching measurements enabled by the EMCal in ALICE, by providing large acceptance for back-to-back correlation measurements of jets and hadrons.

The new calorimeter, called the “DCal”, is a large lead-scintillator detector with photo-diode readout placed in the opposite azimuth to the existing electromagnetic calorimeter (EMCal). This is the optimal configuration for the measurements of back-to-back jets, which originate in the interactions of ultra-high-energy quarks and gluons. The addition of the DCal in ALICE makes hadron-jet and jet-jet correlation measurements possible with high statistics over a very broad kinematic range, expanding ALICE's physics capabilities significantly.
