CONTEXT


The Centre of Particle Physics of Marseille is a Joint Research Unit (UMR 7346). The laboratory is part of the French National Institute for Nuclear and Particle Physics (IN2P3), under the joint supervision of CNRS and Aix-Marseille University.

The CPPM is involved in the implementation of detectors for CERN's major experiments. In particular, it is involved in the design of the integrated circuits required for the construction, assembly and development of these detectors.

The CPPM regularly works on industrial collaboration projects related to its core business. For example, the CPPM and a local company have launched a collaboration to design and produce an integrated circuit dedicated to the detection of ionizing radiation. The analog front-end of the circuit will bias the detectors, amplify and shape the signals. In this project, the noise factor of the analog stages is the critical point for the design, since it directly impacts the performances of the ASIC + detectors assembly. Optimizing the signal-to-noise ratio (SNR) is therefore a major challenge to be overcome during the study, especially as it will have to be done in conjunction with optimizing power consumption.

The laboratory has a permanent staff of around 40 researchers/teaching-researchers and 80 engineers/technicians/administrators, plus some 40 PhD students and foreign visitors. The position is located in the electronics department, which employs around twenty people.

Missions


The SVOM project is a Franco-Chinese space mission dedicated to the study of transient phenomena in the Universe, particularly gamma-ray bursts, which are highly energetic explosions detectable even in the very distant Universe. The launch took place in June 2024, and the operational phase is ex-pected to begin in late January 2025. The specifics of such a mission are: (i) the transient nature of the sources studied: it is not known in advance in which direction in the sky a gamma-ray burst will occur, and once the gamma-ray burst is detected, real-time action is required to study it because its duration is brief (a few tens of seconds for the main emission, a few hours or days for the afterglow emission); (ii) the combination of wide-field instruments (for detection) and narrow-field instruments (for follow-up) at multiple wavelengths (gamma, X, visible, near-infrared) to successively monitor all phases of the emission of the phenomenon; (iii) the rapid availability (or even near real-time availability for certain key data) of a portion of the data to the international community to encourage follow-up of transient events detected by other instruments outside of the SVOM collaboration. In particular, the satellite is supported by a network of ground-based optical telescopes located around the world, including the COLIBRI telescope. This telescope, installed at San Pedro Mártir in Mexico, is primarily dedicated to the optical and infrared follow-up of alerts from the SVOM satellite.

The CPPM is one of the French laboratories participating in the SVOM project, contributing to scien-tific tasks (gamma-ray burst study program and multi-messenger follow-up) and technical ones (devel-opment of the image analysis pipelines for the COLIBRI telescope, its interfaces with other analysis centers, and the telescope's monitoring center).

Links describing the SVOM space project and COLIBRI:

https://www.svom.eu

https://www.colibri-obs.org


Activities


The main missions of the recruited engineer are:

· Development and maintenance of the automatic image processing pipelines for the three cam-eras of the COLIBRI telescope, one of which will be equipped with a near-infrared sensor.

· Development and maintenance of the Instrument Center (GIC), which is a web application de-signed to monitor the various subsystems of COLIBRI and track their long-term performance.

· Participation in the telescope operations (COLIBRI telescope operation shifts, COLIBRI In-strument Scientist shift for the SVOM collaboration).

· Participation in scientific activities related to the objectives of CPPM: study of gamma-ray bursts, multi-messenger follow-up for major neutrino and gravitational wave alerts.


Skills


The candidate should hold an engineering degree (Master's/Bac+5) or have a PhD at the start of the contract. Experience in a fundamental research laboratory would be highly appreciated. A strong background in astroparticle physics, astrophysics, and astronomy would be a significant advantage.

For technical contributions, the candidate should have strong skills in Python and Bash programming, knowledge of software development in open environments (Git, Docker containerization, unit tests, software quality), and web programming skills (JavaScript, HTML, Node.js).

Proficiency in written and spoken technical English (being able to write technical reports in English, present results orally, and participate in meetings and video-conferences in English) is essential (B2 level or equivalent).

The recruited individual must have excellent teamwork skills. Experience in working within interna-tional teams and large collaborations is highly recommended. In this regard, the recruited person will be required to participate in collaboration meetings in France and possibly in China and Mexico.

Internship supervisor:
Yannick Boursier - +33 (0)491827641 - boursier@cppm.in2p3.fr
Description:

Mission :


The research work forms part of the Prompt-Gamma Time Imaging (PGTI) project, funded by the ERC, which aims to provide an instrumental and methodological proof of concept for real-time monitoring, using real data, of the emission distribution of Gamma Prompts (GPs) in the context of hadrontherapy. A detection system placed around the patient - consisting of a beam monitor and gamma detectors - with a temporal resolution of 100 ps provides time-of-flight measurements of the particles involved in the treatment. The first objective of the proposed mission is to use this data to be able to detect as early as possible any significant divergence between the actual treatment and the treatment plan (simulated upstream), and to stop the treatment if necessary. The final objective is to be able to estimate the dose deposition profile from the time-of-flight measurements with sufficient accuracy to adjust the treatment in real time in relation to the treatment plan.


Activities :


The researcher recruited will join the imXgam team at the Centre de Physique des Particules de Marseille, which is responsible for developing the data processing methodology for the PGTI project.


He/she will develop a research activity at the interface between information sciences and medical physics in order to explore applications of artificial intelligence for time-of-flight data in hadrontherapy. He/she will pursue the following main objectives: i) perfect our approach to 3D reconstruction of GP vertices based on an optimisation problem that incorporates the physics of hadrontherapy (e.g. in particular by analysing simulated and real data available in order to incorporate suitable regularisations). The results obtained at this stage will be used in particular to optimise the design of the instrument for maximum spatial resolution; ii) evaluate the contribution of machine learning and deep learning methods to jointly estimate the 3D distribution of GP vertices and the anatomical changes (i.e. in electron density) between the time of the treatment plan and the time of the actual treatment. This essential quantity is often estimated beforehand with significant uncertainties that need to be compensated for. Various strategies will be studied and the most relevant (transfer learning, use of Generative Adversarial Networks) will be evaluated on real data with feedback from doctors and radiophysicists.


Context :


The researcher will be part of the PGTI project funded by an ERC Starting Grant led by Sara Marcatili (LPSC) as part of a tripartite collaboration between the Laboratoire de Physique Subatomique & Cosmologie (LPSC) in Grenoble, the Centre de Physique des Particules de Marseille (CPPM) and the Centre Antoine Lacassagne (CAL) in Nice.

He/she will benefit from the rich and stimulating multidisciplinary working environment of the imXgam team, the CPPM and the Luminy Campus, including access to the know-how and computing resources of the IN2P3 Computing Centre.
