The ATLAS Positron Experiment (APEX) is designed to investigate narrow structures observed in the energy spectra of positions and positron-electron coincidences produced in collisions of high Z ions with high Z targets at Coulomb barrier energies. The apparatus consists of a large diameter uniform-field solenoid mounted transverse to the beam direction. Scattered heavy ions are detected in a gas-counter array. Electrons and positrons transversing the solenoid are detected in highly segmented silicon arrays surrounded by position sensitive NaI detectors for positron identification. The concept of APEX and the current status of the apparatus will be discussed.
