March 20, 2020 | Phoebe: a complete dose-simulation code

phoebe cea list 250A powerful and modular new computing code was developed to simulate the dose of radiation received by patients during radiation therapy and medical imaging procedures.

Researchers at List, a CEA Tech institute, developed a particle transport code that uses the Monte Carlo method. The goal is to simulate the dose of radiation received by patients during radiation therapy and medical imaging. To ensure optimal control of the simulation code in both technical terms (physical models and geometries) and in legal terms (licensing), the researchers developed a new code called Phoebe (PHOton and Electron Beams).

They used the validated physical models from Penelope, the Monte Carlo code most often used in radiation therapy, as the starting point for the new code, which was written in a programming language that is more portable and modular. For instance, because of the programming language chosen, Phoebe can be used on all operating systems, from PCs to smartphones. And, because Phoebe is modular, new features can be integrated later on. In fact, Phoebe was recently given a model to simulate physical phenomena at a cellular scale used to determine how a patient will respond to radiation-therapy-enhancing nanoparticle injections. List engineers are currently developing new models to factor in the entire dose received by the patient during a radiation treatment, including in areas far away from the tumor.

Phoebe came through laboratory validation testing with flying colors and the technology is mature enough at this stage for the models to be made available to a broad community of users via an open source platform.

March 19, 2020 | Keep connected!

message covid 2020 CEA List 2020 250In accordance with government containment guidelines, dedicated to controlling the spread of COVID-19 and ensuring everyone's safety, the CEA has suspended its on-site activities until further notice.

During this exceptional period, the CEA List teams remain mobilized to continue working on our R&D projects for our industrial and research partnerships. As of Monday, March 16, we have put in place the digital resources necessary to ensure our collective missions and commitments.

Keep connected and good luck to everyone.

 

 

13 février 2020 | Labellisation Carnot : le CEA List de nouveau labellisé !

Logo CARNOT CEA LIST 2020À la suite de l'appel à labellisation lancé en juin 2019, le ministère de l'Enseignement supérieur, de la Recherche et de l'Innovation a annoncé, le 7 février 2020, les noms des 39 instituts de recherche labellisés « Institut Carnot ». Parmi eux, Le List, institut de CEA Tech, a obtenu le renouvellement de sa labellisation.

Le List : un institut labellisé Carnot depuis 2006

Le List est labellisé Carnot depuis 2006 pour la qualité et le professionnalisme de ses activités de recherche partenariale avec les acteurs économiques.

Ce type de dispositif permet de lancer des projets de recherche exploratoire dans de nouveaux domaines en rupture et ainsi d’évaluer de nouvelles idées en amont. Il permet de mettre en œuvre des stratégies de collaboration, sous forme de chaires, bourses ou projets et de réaliser des démonstrateurs technologiques.

Le List est donc labellisé de nouveau sous le nom de Carnot CEA List.

February 13, 2020 | Additive manufacturing: Parts can now be inspected as they take shape

FA 250​Increasingly, additive manufacturing techniques are the choice for producing parts with very complex shapes. A new quality control process was recently developed to ensure that these parts are free from defects while they are being manufactured.

Directed Energy Deposition (DED) is an additive manufacturing process in which layers of material are deposited to produce metal, polymer, or ceramic parts. A laser or electron beam is used to melt each layer of the material—in powder or wire form—as it is deposited. Parts with very complex shapes that would be impossible to manufacture using conventional techniques can be obtained with DED. In fact, DED is rapidly gaining traction in the automotive, aeronautics, medical, and other industries that demand defect-free parts. List, a CEA Tech institute, recently developed an interferometry-based method for detecting even the tiniest microporosities and cracks during the DED process.

A pulsed laser generates elastic waves, both at the surface of and deep within the object being manufactured. Another laser detects these waves, with abnormal propagation indicating defects. The researchers successfully synchronized the probe-robot's trajectory with that of the DED robot: So successfully that the system can detect defects measuring just a hundred microns.

This high-performance technology was unveiled at the Formnext trade show in Germany in November 2019, garnering interest from a number of potential industrial users. Additive manufacturing equipment maker Beam, LIST's partner on the project, is currently planning to integrate the technology into its machines.

February 6, 2020 | Kalray sets sights on Chinese market

kalray processeur coolidge 250Kalray, which completed its IPO last year, recently signed a distribution contract that will bring its intensive computing solutions for artificial intelligence to the rapidly-growing Chinese market.

Artificial intelligence is no longer just something out of a sci-fi novel—it is making our electronic gadgets, digital assistants, and even our cars more and more "human". The number of potential uses for AI is growing, and demand for increasingly powerful processors is higher than ever. Founded in 2008 as a spinoff of CEA Tech institute Leti, Kalray has developed a manycore processor with up to 80 cores specifically for the autonomous vehicle and data center markets.

Today Kalray is present in several European countries as well as in the United States. The company is now setting its sights on China, with its recent announcement of a distribution partnership with Intron Technology, a provider of high-growth technologies to markets that include China. The partnership will give Kalray a prime opportunity to bring its smart processor and local tech support to manufacturers in China.

Kalray's architecture is capable of processing large volumes of data and trillions of instructions in parallel and in real time. The company has just released the third generation of its processor, which was designed for the execution of advanced applications for artificial intelligence.
