Introduction
The ALICE detector shown here at right
consists
The ALICE - USA Collaboration proposes to add a large area
EMCal to the experiment to extend the measured
momentum range for photons and electrons and to provide a measurement of jet energy and jet fragmentation
functions. Once a large area EMCal is added, ALICE will resemble a combination of the
PHENIX and STAR experiments,
with all of the combined capabilities of these two experiemnts, able to adddress the full range of observables
in ultra relativisitic heavy ion collisions.
proposing to join the ALICE experiment at the CERN LHC.
of two seperate spectrometers: the main, central rapidity
spectrometer to measure hadrons, electrons and photons, and a forward rapidity spectrometer to measure muons.
The central part comprises a large solenoidal magnet (from the L3 experiment) with ITS (Inner Tracker System),
TPC, TOF, RICH and TRD (Transision Radiation Detector) to measure hadrons and eletrons, and the PHOS (PHOtons
Spectrometer) (PHOS) to measure photons and electrons.
