New phoswich counters were developed that will be capable of detecting low flux hard x rays/gamma rays from astronomical objects. The new phoswich counter consists of a small inorganic scintillator with a fast decay time (the detection part) glued to the interior bottom surface of a rectangular well-shaped block of another inorganic scintillator with a slow decay time (the shielding part). Here, the well-shaped shielding part acts as an active collimator as well as an active shield. A detector system was built which consists of 64 such phoswich counters: newly developed scintillator (GSO) is used for the detection part and CsI(Tl) is used for the shielding part. The total geometrical area of the 64 detection parts is about 740 sq cm and its 3 sigma sensitivity is expected to reach below 10-5/sq cm/s/keV up to 700 keV. With several improvements such detectors will be able to detect hard x rays/gamma rays at a flux level around 10-6/sq cm/s/keV up to 2 MeV.
