Cooperation across Europe for Cd(Zn)Te based Security Instruments, COCAE (FP7 Security)
Jan 15, 2009
The COCAE project develops an instrument for localization and identification of radioactive sources. For the localization task it will exploit the Compton scattered photons within its detecting layers. It is based on pixilated Cd(Zn)Te matrices in a stacked configuration. It has ten parallel planar layers placed 2cm apart the one from the other and made of pixilated 2mm thick Cd(Zn)Te crystals occupying an area of 4cmx4cm. Each detector’s layer consists of a two dimensional array of pixels (100x100) of 400μm pitch, bump-bonded on a two dimensional array of silicon readout CMOS circuits. Al2O3 supporting printed circuit boards house the hybrid detectors along with additional processing circuitry
