The pseudorapidity region $2.5<|\eta|<4.0$ in ATLAS is a particularly complex
transition zone between the endcap and forward calorimeters. A set-up consisting of
$1/4$ resp. $1/8$ of the full azimuthal acceptance of the ATLAS liquid argon endcap
and forward calorimeters has been exposed to beams of electrons, pions and muons in
the energy range $E \le 200~\GeV$ at the CERN SPS. Data have been taken in the
and forward calorimeter regions as well as in the transition region. This beam test
set-up corresponds very closely to the geometry and support structures in ATLAS. A
detailed study of the performance in the endcap and forward calorimeter regions is
described. The data are compared with MC simulations based on GEANT 4 models.
