A new phoswich counter capable of detecting low-flux hard X-ray/gamma-ray from localized sources is presented. The counter is based on a small inorganic scintillator with a fast decay time (the detection part) glued to the interior bottom surface of a well-shaped block of another inorganic scintillator with a slow decay time (the shielding part). The well-shaped shielding part acts as an active collimator as well as an active shield. A pulse-shape discriminator is used to select hard X-rays/gamma rays that have deposited energy only in the detection part. A detector system consisting of 64 phoswich counters based on a Gd2SiO5 scintillator for the detection part and a CsI(Tl) scintillator for the shielding part was flown onboard a balloon. It is concluded that the well-type concept is very effective in reducing the external and internal backgrounds.
