Photon-Enhanced Thermionic Emission

The photon enhanced thermionic emitter is a new solar energy harvester suitable for operations at high temperatures. We propose the use of a bio-inspired light-trapping structure to enhance the solar flux collection

Helicon Plasma Thruster For Space Missions

The use of helicon sources as thrusters for space propulsion has been envisaged as a robust, scalable, reliable and long-life device. The Helicon Plasma Thruster (HPT) is presented as a potentially durable, throttlable and high thrust-to-power ratio device, with intermediate specific impulse and competitive thrust efficiency.

FLEX/S3 Tandem Mission Performance Analysis and Requirements Consolidation Study

While most Earth Observation missions based on passive optical methods are intended to measure the light “reflected” by the surface, FLEX uses a completely innovative approach based on the measurement of the light “emitted” as fluorescence by terrestrial vegetation. Such fluorescence emission by vegetation has never been measured from space, which makes FLEX a true Explorer mission providing a type of information never available before.

FLEX/SENTINEL-3 TANDEM MISSION PHOTOSYNTHESIS STUDY

Chlorophyll fluorescence (CF) is a natural spectral emission resulting from the interaction of plant chlorophyll pigment with visible light (typically 400‐700 nm). In photosynthesizing tissues, red and far‐red light can be emitted from any chlorophyll‐containing plant tissues which are exposed to light: primarily foliage, but also green stems, green exposed roots, floral structures, many fruits, and green seeds.
