Description
A forward electromagnetic calorimeter (FoCal) based on SiW technology is
being considered as a possible upgrade to the ALICE detector. The main
driving force behind this detector is the ability to measure direct
photons in a so far unreachable part of phase space. It should thus
provide unique information relevant for the study of the small-x
structure of nucleons and nuclei and possible effects of gluon
saturation, among many other interesting physics topics. To achieve
this, the device should in particular feature an extremely high lateral
granularity allowing gamma/pi0 discrimination out to very high momenta.
The main option considered for the high granularity layers are CMOS
pixel sensors. We will discuss the motivation and design principles of
the proposed calorimeter and will then focus on the experience gained
with a full CMOS-pixel calorimeter prototype. We will also discuss the
status of photon identification algorithms to be used with such a
detector.
