Abstract

A large-area pixellated photon counting imaging system, primarily for synchrotron radiation research, is under development. An area of 300 mm]300 mm will be covered by tiling many modules. A module will comprise a 64]448
array of 150 lm]150 lm silicon pixels covering an area of 9.6 nm]67.2 mm. This will be #ip chip bonded to 7 ALADIN readout chips, that each contain a 64]64 array of 144 mm]150 lm pixels. Each readout pixel comprises a pre-ampli"er,
shaper, discriminator, 15-bit counter and 5-bit register that enables threshold adjust, pixel masking and calibrate control. Each pixel is designed to operate at &1 MHz providing a count rate capability of &109 cm~2 s~1. The system will
operate in the energy range from 4 to 25 keV and at a frame rate of up to 1 kHz. The current status of the project is reported, along with the detector guard structure chosen to minimise the dead region around the active volume of the
silicon detectors.
