When the Higgs boson was found in 2012, Paul Lecoq was just one of the physicists who produced it feasible. Now, as principal investigator in the EU-funded TICAL project, he has been implementing his knowledge in creating particle detectors to complications relating to health-related imaging.
From the extremely commencing, I had the intuition that the technologies I was proposing to enhance the overall performance of our particle physics detectors would have a sturdy influence in health-related physics, he suggests.
Until just lately, Lecoq labored at CERN, the European Laboratory for Particle Physics, as complex coordinator for just one of the detectors for the Large Hadron Collider. Regarded as a calorimeter, the detector makes use of dense crystalline blocks, termed scintillators, to capture particles as they move by. The vitality of the particle seems as flash of light-weight which is picked up by sensitive photodetectors.
In exercise, a substantial-vitality particle will create a shower of other particles in the scintillator but the response of the scintillator is just far too sluggish to record the complexity of the shower.
Nanocrystals
With funding for the TICAL project from the European Research Council, Lecoq set out to devise a new form of scintillator that could much more exactly record the posture and timing of functions in the shower. What I want is a reconstruction of the spatial improvement of the shower and also the time I want to know the dynamics of it.
His remedy was to use nanocrystals tiny crystals of scintillator materials that are modest more than enough for quantum results to dominate and for a captured particle to emit a a great deal sharper flash of light-weight. By sandwiching slender levels of nanocrystals involving sheets of conventional scintillator, Lecoqs meta-scintillator enables the particle shower to be tracked much more accurately.
Meta-scintillators could tremendously enhance the particle detectors at CERN but that is not the total story.
For lots of years, Lecoq focused on PET (Positron Emission Tomography) scanners, the imaging devices used to probe the interior of the human overall body, particularly for cancer analysis. They depend on detecting gamma rays utilizing a great deal the identical concepts as CERNs particle detectors.
I used to say that the a hundred-tonne calorimeter, the construction of which I was accountable for at the Large Hadron Collider, is nothing at all but a gigantic PET scanner, he jokes.
10 picosecond obstacle
At current, the most effective PET scanners can time the arrival of a gamma ray to greater than five hundred picoseconds. With the TICAL meta-scintillators ultimately able of a precision of ten picoseconds fifty periods greater Lecoq envisages long term PET scanners capable to create a great deal sharper visuals. They would also demand a great deal fewer radioactive materials and possibly have broader apps in medication.
Lecoq is currently searching for sponsors for a Ten picosecond challenge to design and style and build gamma-ray detectors for PET apps able of this increased time resolution.
TICAL concluded at the stop of 2018 but Lecoq, retired from CERN, is now co-CEO of Multiwave Metacrystal, a firm established to commercialise the get the job done of the project. It is setting up a laboratory in collaboration with the Polytechnic College of Valencia to develop meta-scintillators. Originally, they would be for PET scanners although they also have potential for other industrial and protection apps.
Lecoq sees the project as a typical example of how European funding can allow for a wholly ridiculous idea to mature to the stage in which it can be commercialised for the superior of society. For me, the ERC grant was fantastic. The European Commission has truly performed the role it ought to play.
