TreeView Phase 2

Role	Start date	End date	Funding source
Co-investigator	01 Oct 2021	31 Mar 2022	UKSA UK Space Agency
TreeView is an Earth Observation mission that will achieve precision forestry from space in the support of Nature-Based Solutions to tackle climate change. The expansion of tree cover is a critical component of the path to net zero but reaching this target will require extensive management of this resource. Through leveraging next-generation optical sensor technology and innovations across the payload and spacecraft development, TreeView will provide multispectral data at a ground sampling resolution on the scale of individual trees, providing measurement and monitoring capabilities at an unprecedented level. The proposed project builds on the successfully concluded feasibility study and will progress the hardware and software elements of TreeView to a Preliminary Design Review (PDR). The activities will focus on the development of the instrument from an initial concept to a finished design. The satellite bus is being developed and qualified through a European Space Agency funded project and has already passed its PDR. A mission specific “delta” PDR will be held in future phases of the TreeView programme once the payload PDR’s have also been passed to confirm the complete satellite is at sufficient design maturity. The data processing pipeline embodied largely in the Ground Segment, and outputting data products for dissemination, raw data for archiving and utilising ground validation will be reviewed in a Ground Segment PDR. Subject to further funding, the outcome of this project and a successful PDR will enable the TreeView team to commence procurement to develop the Engineering Model of the instrument and payload for the TreeView mission. In parallel spacecraft procurement and development of the Ground Segment through a model of commercially purchased services, national facilities, and support from the science team could commence. TreeView is on track to develop and launch the satellite and return data by the end of the Financial Year 2024-25.

TreeView: developing new capacity for the remote sensing of UK trees and forests

Role	Start date	End date	Funding source
Co-investigator	01 Nov 2020	31 Mar 2021	UKSA UK Space Agency
Tree and forest climate interactions are fundamental to a sustainable future and societal wellbeing. Trees are at the heart of the current political discourse, and the UK government is preparing to launch a strategy to accelerate tree planting and improve the management of existing trees and woodlands. The world is becoming increasingly urbanised, and urban trees are well recognised for their environmental, health and wellbeing benefits. Trees across the rural and urban landscape are going to play a central role as we move towards a net-zero emissions economy. The ability to measure, monitor and map the health and status of the UK’s trees is therefore essential to the UK’s future treescape and urban green infrastructure. Currently, tree identification can be achieved with high spatial resolution panchromatic imagery, but we need to go beyond this. We need to be able to not only map species within mixed assemblages, but also characterise the health and size of the trees. Furthermore, we need to be able to measure the particular configurations of urban environments and the small-scale but widespread plantings that are likely to feature prominently in planting programmes. Importantly, we need to be able to monitor changes over time – to quantify carbon sequestration; assess vulnerability and detect the onset of climatic stress or disease outbreak to facilitate early intervention; and to measure the success and monitor compliance of tree planting programmes. This requires going to the spatial scale of tree crowns but capturing the spectral information that will provide the information for classification and characterisation. Advances in both sensors and process understanding is closing the gap between canopy reflectance properties and its functional meaning, opening the possibility of detailed studies at the scale of individual trees and their responses to global change from space. Species identification and mapping has been demonstrated from airborne hyperspectral sensors, enabling species mapping across forests and urban areas. In this project we will push the limits of leading CMOS TDI sensors and optimise system configuration to develop a new platform for the classification, characterisation and monitoring of trees across urban and rural landscapes. Band selection will provide information on both plant health and will feed into classification algorithms developed from extensive ground truthing data. In this pathfinder phase of the project, our objectives are to (could include): 1. Refine band selection based on key vegetation characterisation indices and sensor constraints (from starting point of bands a,b,..f) 2. Develop classification algorithms from airborne hyperspectral data and extensive ground-truthing data sets. 3. Collect new airborne data specifically for one target market: railways 4. Produce the system requirements document for TreeView 5. Produce the mission requirements document for TreeView 6. Perform market analysis of end users across local and national government, commercial and research sectors

Role	Start date	End date	Funding source
Co-investigator	01 Apr 2019	31 Mar 2022	UKSA UK Space Agency
The Open University is part of the instrument consortium developing the Soft X-ray Imager for the SMILE spacecraft. In this role, researchers at The Open University have informed the development of the bespoke detectors in order to optimise them for soft X-ray performance, performed initial development of facilities and equipment to characterise the devices and performed simulations of the environment that the SXI instrument will experience in order to inform the instrument design. This funding will allow this research to continue by: - evolving the radiation environment simulations as the instrument, spacecraft and mission design matures, particularly exploring observation strategies to minimise the damage to the CCD focal plane; - characterising and optimising the performance of the newly manufactured flight-like detectors, particularly following expected end-of-life radiation levels; - performing calibration activities on the flight detectors, using synchrotron X-ray and lab-based measurements; - developing and verifying the on-board algorithm for identification of soft X-ray events within the image data returned from the detectors.

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

Role	Start date	End date	Funding source
Co-investigator	01 Feb 2017	31 Jan 2021	STFC 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.

Cryogenic irradiations: a realistic study of the impact of radiation on detectors in space

Role	Start date	End date	Funding source
Lead	01 Oct 2016	30 Sep 2020	STFC Science & Technology Facilities Council
Charge-Coupled Devices (CCDs) have long been the detectors of choice for space astronomy missions. When placed in orbit, the devices can experience a harsh radiation environment. The radiation incident on the detector will act to damage the silicon lattice, creating defects that lead to the formation of "traps". These traps capture signal that is being read out of the device, leading to smearing and signal loss. Before any mission is launched, it is vital that the impact of radiation is studied in detail such that appropriate shielding is used along with the development of novel readout techniques and correction algorithms to mitigate the damage that remains. Currently, standard practice dictates that radiation testing of devices is carried out at room temperature, despite the fact that the detectors will be kept cold during operation in orbit. The traps that are created after irradiation will migrate through the device until they reach a stable state, but the stability of any particular defect structure is strongly dependent on temperature; the traps present at room temperature may be dramatically different to those present when a device is irradiated cold and kept cold. Literature on the so called "cryogenic irradiation" is sparse, but there are reports of a factor of 2-3 difference between the impact of radiation at room temperature compared to the more realistic cryogenic irradiation. ESA's Euclid mission, aiming to map dark matter and energy, is dependent on a complete and thorough understanding of the impact of radiation on the detectors to allow for correction against radiation to reduce the smearing by up to 300 times. Hubble is able to correct by approximately a factor of 30, one order of magnitude less than that required for Euclid's high precision measurements. Cryogenic irradiations present many challenges as the devices must be kept cold (and therefore under vacuum) at all times, whilst irradiating and for a period of weeks or months after the irradiation. Equipment and techniques have been developed within the CEI over the past 12 months that have allowed our first cryogenic irradiations to take place. Early results demonstrate that there is a dramatic difference between the cryogenic results and those performed at room temperature, including the presence of very different trap species. This studentship proposal will involve a succession of cryogenic irradiations of n-channel CCDs, using newly developed apparatus, to feed directly into the CEI's current Euclid research. Not only will this feed into Euclid, but the fundamental understanding developed will feed into other future missions such as Plato, JUICE and WFIRST to name but a few, and also allowing comparisons to be made to current research into the cryogenic irradiation of p-channel CCDs. Devices will be provided in-kind by the industrial partner, e2v technologies, alongside in-kind time offered from e2v employees. The timescale for this studentship (2016-2019) will allow the student to feed into the Euclid programme at this most appropriate time.

CMOS Image Sensors with High Quantum Efficiency

Role	Start date	End date	Funding source
Co-investigator	18 Feb 2015	30 Sep 2016	UKSA 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.
