Test of 24 strip line radiation detector based on semi-insulating GaAs using X-ray source

Line detector with 32-strips based on semi-insulating GaAs is fabricated. Analog and digital read-out electronic chain with 24 read-out channels with the strip line detector is connected. The progressive SMD technology with automatic assembling of electronic devices for readout front-end electronic is used. Testing of counting ability of each strip with micro collimated X-ray source up to 60 kV is carried out. The cross talk between neighbouring strips is analyzed.
