Job Description
As part of the CERN EP strategic R&D program, Work Package 1.4 focuses on advancing the fundamental understanding and optimization of solid-state particle detectors for future particle colliders.
The activities within WP 1.4 aim to optimize, model, and enhance the radiation tolerance of sensors for high-radiation environments and fast-timing applications.
In addition, the work involves developing state-of-the-art characterization and testing infrastructure for semiconductor sensors in High-Energy Physics (HEP) applications.
Key Responsibilities:
* Characterizing sensors using laser-based Transient Current Techniques (TCT and TPA-TCT), beta source measurements, and analyzing radiation-induced defects through Thermally Stimulated Currents (TSC) and Deep Level Transient Spectroscopy (DLTS).
* Collaborating closely with the WP 1.4 team, external collaborators, and industrial partners.
* Contributing to the supervision and mentoring of students and providing support to users of the SSD laboratory.
Key Projects:
* Characterization of LGADs produced in the framework of DRD3 projects
* Development and implementation of upgrades to an existing Two-Photon TCT setup
* Commissioning of a high-temperature DLTS/TSC setup for 4H-SiC sensors
* Characterization of Si and SiC devices produced for defect-spectroscopic analyses
* Exploration of novel sensor designs for fast timing/harsh-radiation environments
Your Profile
Skills
* Expertise in solid-state detectors (silicon and/or silicon carbide)
* Expertise in handling and building laboratory bench tests
* Knowledge in radiation damage to solid-state detectors and damage modelling
* Proficiency in signal readout and analysis
* Ability to work independently, take initiative and engage in hands-on activities to contribute effectively to our projects
Desirable Skills:
* Knowledge on beam optics for laser bench tests
* Knowledge in LabVIEW and/or control software tools
* Fluent in English, the ability to work in French would be an advantage.
Eligibility Criteria:
* You are a national of a CERN Member or Associate Member State.
* You have a professional background in Applied Physics (or a related field) and have either:
o a Master's degree with 2 to 6 years of post-graduation professional experience;
o 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.
About the Position
This position involves working in Radiation Areas, and may require work during nights, Sundays and official holidays, when required by the needs of the Organization.
