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

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.
