NSTP3-R1/e2v Characterisation of TDI CMOS

RoleStart dateEnd dateFunding source
Co-investigator01/Jan/201731/Dec/2017UKSA UK Space Agency
The CEI have been invited by e2v to collaborate on a bid into the UKSA NSTP3-R1 call, with e2v as the lead organisation. The CEI element of this bid is to perform electro-optic characterisation of a new Time Delay Integration (TDI) CMOS image sensor developed by e2v before and after gamma irradiation of the sensor.

Mitigation strategies against radiation-induced instrument background for space astronomy missions

RoleStart dateEnd dateFunding source
Co-investigator01/Oct/201631/Mar/2020STFC (Science & Technology Facilities Council)
Instrument background affects all space astronomy missions. High energy particles and gammas can be detected by the cameras on board and some may be indistinguishable from the photons that the mission aims to measure. The particles that hit the detector, and many more that don't, will pass through the material surrounding the detectors and can generate secondaries that themselves may be detected, from X-rays to soft electrons. It is the detection of these primary and secondary events that we refer to as instrument background, or the "quiescent non-X-ray background". The overall sensitivity of the cameras can take a huge hit from the presence of instrument background, with XMM-Newton being a prime example. The instrument background observed in orbit was many times higher than that which had been predicted pre-launch. Studies in the CEI back in 2006, started under the STFC CASE studentship of David Hall, led to the understanding and first explanation of this mysterious increase in background. Our simulations showed that soft electrons that were knocked from atoms in the innermost few microns of the shielding could be detected and appeared as X-ray-like events. Based on the previous research mentioned above, the Open University is leading the development of instrument background mitigation for the Athena Wide Field Imager (WFI) through study of graded-Z shielding. Simulations using Geant4 will be developed alongside experimental verification of the models. These simulations and the experimental campaign will investigate the use of graded-Z shielding to reduce the background progressively with layers of lower and lower Z moving in towards the detector. The aim in this studentship will be to contribute towards the simulation and experimental testing of the graded-Z shielding through phase A/B1 of the Athena studies; perfectly timed to coincide with the studentship of 2016-2019 such that the student will be able to feed into the mission development at this most appropriate stage. However, despite the benefits that are expected from a new and novel graded shielding approach, some particles and photons will still make it through to the detector. As the total sensitivity of the camera system will depend on a multitude of different factors, including both the background and the quantum efficiency (QE) of the device, novel methods to improve the sensitivity at the expense of the detector QE have been discussed. The student will look into the use of layers directly deposited onto the detector to absorb the knock-on electrons, reducing the background, but consequently reducing the QE, with the aim of improving the overall sensitivity of the detector system. These developments will not only benefit the DEPFET detectors of the Athena mission, but they will have universal applications across all detectors used in space applications. Whilst the DEPFET sensors for Athena are not developed by e2v technologies, the company has a great interest in the environment in which their detectors will be placed for many other missions such as Euclid and Plato. The understanding of the environment developed for Athena will be directly relatable to these other missions and other detector technologies. Even more so, the use of thin layers deposited on the detectors to improve overall sensitivity is of particular interest to e2v, and as such they would provide detectors in kind for testing of the shielding and new layers proposed, applying the layers to the devices in house where possible and aiding in the measurement of the QE of the layers.

ESA p-channel contract change notification

Lead05/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.

CMOS Image Sensors for Precision Astronomy

This project is an Industrial CASE PhD studentship managed by the OU and funded by STFC and XCAM Ltd. The STFC funded element of the studentship comes from DPSs STFC quota, this AMS project only relates to the CASE top-up funding from XCAM Ltd. The University of Iowa, with support from the Open University, are developing an X-ray detection instrument (OGRE) to fly on-board a NASA sounding rocket in ~2018. XCAM Ltd have been contracted by The University of Iowa to design, develop and supply a prototype and flight camera system for this rocket based mission, on specification provided by the University of Iowa and the Open University. This is the OGRE Programme. This studentship will support the OGRE Programme through the optimisation of the prototype OGRE camera system, supporting the commissioning of the system and analysing the performance of the system during the flight.

Lead01/Apr/201531/Mar/2020UKSA UK Space Agency
This phase of the grant is to cover the "build phase" (B2/C/D) of ESA's JUICE mission. The CEI will procure, qualify and test the flight model detectors and supply them to DLR for integration into the flight camera. During this project the CEI will provide design inputs to the JANUS camera consortium, support formal ESA meetings, reviews, and telecons with documentation, study the trade-offs in the use of the sensors, particularly recommending operating temperature and temperature stability, and the strategy for removing prompt electron events from the images. We are also completing the modelling of the effects of electron radiation on mission science and image quality, and will perform qualification radiation damage assessment on the technology with protons, electrons, gammas and heavy ions. The CEI will also perform acceptance radiation damage assessment on devices from the flight wafer.

CMOS Image Sensors with High Quantum Efficiency

RoleStart dateEnd dateFunding source
Co-investigator18/Feb/201530/Sep/2016UKSA UK Space Agency
One of the main image sensors for space applications today is the CCD due to its high image quality, low noise and large sensitive area. Through back illumination of fully depleted devices the CCD demonstrates quantum efficiency (QE) above 90% over much of the visible range. Over recent years, new CMOS image technology has been under development and now can achieve similar low noise and large area, however, deep depletion has remained elusive due to the more complex CMOS structure, combined with typically low operating voltages. This project aims to develop the next generation of CMOS image sensors suitable for Earth observation, ground and space-based astronomy, and other science applications requiring high QE in the red and near-infrared parts of the spectrum. The main innovation is the achievement of high QE by full depletion of the thick sensitive semiconductor layer using reverse substrate bias. In this way sensitive detector thickness of 100 µm or more can be realised, instead of the current 5-10 µm thick devices. The development will concentrate on building silicon CMOS image sensors using pinned photodiode photosensitive elements, capable of achieving science-grade imaging performance. The technological advances from this work will allow many space-based imaging instruments to transition from CCD to CMOS devices and benefit from better radiation hardness, higher readout speeds, increased level of integration and lower power dissipation. At the Centre for Electronic Imaging (CEI), based at the Open University, we have performed preliminary modelling and have filed a patent application to enable the construction of fully depleted CMOS image sensors using reverse substrate bias. Under this programme we would aim to design, manufacture and test prototype CMOS image sensors based on our patent application.
