€4 million funding awarded to medical accelerators network

Publication date:


Cancer is a major health problem and it is the main cause of death between the ages of 45–65. Although significant progress has been made in the use of particle beams for cancer treatment, extensive research is still needed to maximise healthcare benefits. Improving ion beam therapy for enhanced cancer treatment is the goal of a new European research and training network that will focus on the Optimisation of Medical Accelerators (OMA).

An ambitious European mission is being planned to answer fundamental questions about how planetary systems form and evolve. ARIEL will investigate the atmospheres of several hundreds planets orbiting distant stars. It is one of three candidate missions selected last month by the European Space Agency (ESA) for its next medium class science mission, due for launch in 2026.  The ARIEL mission concept has been developed by a consortium of more than 50 institutes from 12 countries, including UK, France, Italy, Germany, the Netherlands, Poland, Spain, Belgium, Austria, Denmark, Ireland, Portugal.  The mission will be presented today at the Pathways 2015 conference in Bern, Switzerland, by ARIEL’s Principal Investigator, Prof Giovanna Tinetti of UCL. 

Revealed: positronium’s behaviour in particle billiards

First measurements of the differential positronium-formation cross-sections

Publication date:

Positrons are the antimatter version of electrons and so their fate in a matter world is ultimately to annihilate. However, prior to this, a positron may combine with an electron to form a matter-antimatter hybrid called positronium. This is akin to a hydrogen atom with the proton replaced by a positron. Fundamental to our understanding of the physical universe, positron and positronium are these days also acknowledged as being fantastically useful in practical applications such as probing material properties and medical diagnostics. However, there is still much that we do not know for sure about the details of the interactions of these particles with ordinary matter. For example if, in a collision with an atom or molecule, a positron captures an electron, in which directions is the positronium likely to travel and with what probability?

ESA shortlists three space missions with major UCL contributions

Publication date:

Mission themes

The European Space Agency has announced the shortlisted proposals for its next mid-sized science mission.

All three proposed spacecraft have significant contributions from UCL, which means the university will be guaranteed a role regardless of which is chosen. The candidates are in the areas of exoplanet science, plasma physics and X-ray observations of high-energy phenomena, with teams including academics at UCL Mullard Space Science Laboratory and UCL Physics & Astronomy.

New calculations to improve carbon dioxide monitoring from space

Publication date:

CO2 Satellite

How light of different colours is absorbed by carbon dioxide (CO2) can now be accurately predicted using new calculations developed by a UCL-led team of scientists. This will help climate scientists studying Earth’s greenhouse gas emissions to better interpret data collected from satellites and ground stations measuring CO2.
