A universal model for detector simulations for space applications
RoleStart dateEnd dateFunding source
Co-investigator01 Feb 202131 Jan 2025ESA (European Space Agency)

ESA, in partnership with ESO, is developing a general detector simulation framework called Pyxel, to be able to share a single well-understood framework among many projects and missions. Due to the advanced research into detector physics and simulation being done at the CEI, ESA has agreed to co-fund a PhD studentship to do more research of the physics and fundamental understanding of the detectors for a variety of applications and using this new knowledge to develop exciting new capabilities for Pyxel linking it with the CEI involvement in space missions such as Euclid, SMILE, JUICE, and Gaia.

ESA p-channel contract change notification
RoleStart dateEnd dateFunding source
Co-investigator05 Sep 201601 Sep 2017ESA (European Space Agency)

The CEI have been working under contract to ESA (CLS-404-14) on an investigation in the performance characterisation and radiation testing of p-channel CCDs. This work is now nearing completion and ESA have indicated that they would like to fund an additional study under a contract change notification (CCN). This additional study will focus on the evolution of defects within a back illuminated p-channel and n-channel CCD204 after the devices have been irradiated, side-by-side, and for a period of time after, whilst cold annealing takes place.
