A design of a detecting module based on a silicon front side illuminated single-sided photosensor array with scintillators has been developed. The array is made on wafers with a diameter of 100 mm from high-resistance Ntype silicon with a specific resistance of 5…10 kOhm·cm, lifetime of minority charge carriers τ>1000 μs and orientation . The elimination of shielding of the photosensitive surface of the array by electrical connection elements is ensured by the use of aluminum-polyimide microcables provided that they are placed on the front side of the array in the gaps between the scintillators. The installation of front-end electronics on the board on the reverse side of the array within the array area allows to create a detecting module of compact size with minimal loss of effective recording area. A module with 64 dete ction cells located in a pitch of 4.1 mm does not exceed an area of 3535 mm.
