A 400mm long linear X-ray sensitive image sensor

A solid-state X-ray sensitive diode array with on-chip serial readout circuitry will be reported. The sensor consists of 128 diodes on a pitch of 400μm. Die size is 50×4mm. Device operates at a 1MHz pixel rate and achieves a sensitivity of 2.3nA/mm 2 for a tungsten tube at 100KeV and 9mA cathode current.
