Le projet SVOM-GFT est un projet franco-chinois dédié à la détection et à l'étude des sursauts gamma dont le lancement est prévu fin 2021. L'équipe du CPPM est impliquée dans la construction et l'exploitation du télescope robotique Colibri qui sera installé à San Pedro Martir au Mexique et qui fournit un suivi optique et infrarouge des alertes du satellite SVOM. Le CPPM est en particulier responsable de la caractérisation scientifique du détecteur Alfa, détecteur infrarouge à pixels hybrides, développé par Sofradir, comprenant 2kx2k pixels, qui sera installé dans la caméra infrarouge Cagire sur Colibri. Dans le cadre du projet Cagire, l'ingénieur-e devra 1) prendre en charge le banc de test existant en salle propre ISO7 au CPPM ainsi que la chaîne d'acquisition du détecteur Alfa ; 2) modifier et valider le cryostat de caractérisation en collaboration avec les autres membres de l'équipe ; 3) mettre en place la chaine de validation sur un détecteur de tests ; 4) mettre en œuvre la caractérisation du détecteur final suivant le plan de tests préalablement défini.

La mission LISA est un projet satellite majeur de l'ESA dont l'objectif est de détecter des ondes gravitationnelles par mesure interférométrique grâce à une constellation de trois satellites en orbite autour du soleil. Le consortium des laboratoires français s'est engagé à intégrer et tester les instruments à bord de LISA et le CPPM en particulier est responsable de la caractérisation des photodiodes infrarouges à quadrants indispensables à la mesure interférométrique. Dans le cadre du projet LISA, l'ingenieur-e devra 1) contribuer à la mise en place de nouveaux moyens de test hors salle propre puis en salle propre ; 2) valider ces moyens de tests ; 3) réaliser des tests de caractérisation sur de nouveaux types de détecteurs infrarouges (e.g. photodiodes à quadrants pour le projet LISA).

L'ingénieur-e sera également amené-e à rédiger des rapports en anglais.

L'ingénieur-e devra avoir une formation technique solide en instrumentation, avec de l'expérience en détecteurs. En particulier une expérience sur les détecteurs pour l'astronomie (détecteurs à pixels hybrides, photo-détecteurs et/ou instrumentation infrarouge) sera appréciée. Une connaissance de l'environnement spatial sera un atout supplémentaire.

La durée du contrat est de 15 mois, à pourvoir dès que possible, et pourra être prolongée.

Offre ingénieur d'étude

Applications are invited for a post-doctoral position in the ATLAS group at the Center for Particle Physics of Marseille (CPPM), France. The successful candidate is expected to work on the Phase II upgrade of the ATLAS Liquid Argon (LAr) calorimeter.

CPPM is involved in several major projects in experimental particle physics, astroparticle, cosmology and interdisciplinary applications. The ATLAS group at CPPM gathers about forty-five people, including seventeen staff physicists and eleven PhD students. The group played a major role in the design, construction and operation of the electromagnetic calorimeters, the pixel detector and the trigger system, and pursues a strong R/D effort for planned future upgrades of the detector, notably for the LAr calorimeter, as well as a key contribution to physics analysis in ATLAS.

The successful candidate is expected to take a leading role in the phase II LAr upgrade project and more particularly in the development of data processing algorithms allowing to efficiently compute the energies deposited in the LAr calorimeters in the high pileup conditions expected at the HL-LHC. These algorithms will be based on Artificial Intelligence (AI) techniques such as recurrent neural networks and will be adapted to fit on hardware processing units based on high-end FPGAs. The successful candidate will be responsible of designing the AI algorithms and assessing their performance. She/he will work closely with the engineers designing the electronic cards at CPPM in order to adapt the AI algorithm to the specifics of FPGAs. Candidates with a strong interest for hardware will be encouraged to take part in the design of the firmware to program the FPGAs. The candidate has the possibility to also contribute to physics analysis prospects for the HL-HLC especially the performance of the calorimeter triggers.

The position is funded by the AMIDEX foundation in collaboration with the Technische Universität Dresden. It is for a fixed term of two years, and is based in Marseille, with frequent tavels to CERN. The starting date for the position is autumn 2019 (latest beginning of 2020). Candidates should have a PhD in experimental particle physics by the date of appointment. Good communication skills are expected.

Candidates are invited to send their complete application package (CV, cover letter and statement of research interests, list of publications) to Dr. Georges Aad, aad@cern.ch, and to arrange for three letters of recommendation to be sent to the same address. The review of applications will start in July 2019 and will continue until the position is filled.

Further inquiries about the CPPM ATLAS group and the position should be addressed to Dr. Georges Aad (aad@cern.ch).

The Belle II group at CPPM is inviting applications for two post-doctoral positions to work on searches for tau lepton flavour violating decays.

The successful candidates will be based at CPPM, Marseille, France (https://cppm.in2p3.fr), with travel to KEK, Japan.

The interest of decays involving tau leptons has been dramatically reinforced by the recent anomalies reported in tests of lepton flavour universality violation and rare B decays, suggesting a special role of the third family. In particular, in the presence of physics beyond the SM, the rates of lepton flavour violating tau decays and rare B decays into tau leptons could be just below the current experimental limits. The Belle II experiment, just starting data taking, is an ideal facility to search for these decays.

The CPPM, which has a long standing experience in particle physics accelerator experiments, is joining Belle II in 2019 with an ERC consolidator grant obtained by Justine Serrano. The post doctoral researchers will have a key role in the group, starting the data analysis activity and supervising Ph.D. students. Travel to KEK for Belle II collaboration weeks and shift are foreseen.

Review of applications will start immediately and will continue until the positions are filled.

Contract Period : 12 months renewable twice Expected date of employment : 1 October 2019 Remuneration : Between 2606 and 3615 € monthly gross, according to work experience.

Requirements
- Ph.D. in Experimental Particle Physics
- Excellent analysis and software skills, teamwork abilities and english knowledge
- Experience in Belle II data analysis is appreciated but not mandatory

Interested physicists are invited to submit their application, including a cover motivation, curriculum vitae, list of publications and copies of university degrees. They should also arrange for three letters of recommendation to be sent by referees. Applications from women are highly encouraged.

The applications should be sent to Justine Serrano: serrano@cppm.in2p3.fr
