Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

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.
