Applied Physicist for Pixel-Detector Hybridisation and Testing (EP-DT-TP-2024-46-GRAP)

  • Full-time

Job Description

Your responsibilities

The CERN EP strategic R&D program on technologies for future experiments pursues an extensive development program for advanced silicon detectors. The hybridisation of sensors and readout ASICs and the integration of detectors into functional modules, addressed in Work Package 1.3 (Modules), are among the major challenges for achieving reliable high-performance large-area tracking and timing detector systems with minimal material content at an affordable cost.

The selected Quest candidate will contribute to the R&D in this domain by developing and testing scalable hybridisation and module-building concepts based on newly developed in-house plating and interconnect processes. The candidate will work in close collaboration with the EP R&D WP 1.3 team and its external collaborators.

The foreseen activities include:

  • Contribution to the development and validation of in-house hybridisation processes based on advanced interconnect technologies such as conductive adhesives.
  • Production of functional hybrid assemblies of ASICs and sensors in collaboration with the participating projects.
  • Contribution to the preparation and maintenance of testing infrastructure for laboratory and test-beam measurements.
  • Performance testing of prototypes in laboratory measurements and with particle beams.
  • Reliability tests (thermal cycling, irradiations) on mechanical and functional samples, development of suitable QA and QC procedures for yield measurement and failure classification, performance measurements before and after thermal cycling and irradiations.
  • Contribution to the development and operation of a multi-chip module demonstrator system.
  • Analysis of test data, documentation and publication of results.

Your profile

Skills and/or knowledge

  • The foreseen activities require previous experience with silicon-detector technology.
  • Fluent in English.

Eligibility criteria:

  • You are a national of a CERN Member or Associate Member State.
  • You have a professional background in Physics (or a related field) and have either:
    • a Master's degree with 2 to 6 years of post-graduation professional experience;
    • or a PhD with no more than 3 years of post-graduation professional experience.
  • You have never had a CERN fellow or graduate contract before.

What we offer

  • A monthly stipend ranging between 6194 and 6808 Swiss Francs per month (net of tax).
  • Coverage by CERN's comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
  • Depending on your individual circumstances: installation grant; family, child and infant allowances; payment of travel expenses at the beginning and end of contract.
  • 30 days of paid leave per year.
  • On-the-job and formal training at CERN as well as in-house language courses for English and/or French.

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on
