Applied Physicist for Silicon Detector R&D (EP-LBD-2023-110-GRAP)

  • Full-time

Job Description

Your responsibilities

The candidate will oversee the procurement of small pitch, thin column 3D silicon pixel sensors and follow up the production with the company. They will characterise the timing performance and radiation hardness of a range of samples. The characterisation will be carried out with a dedicated electronic board, both in testbeam and the lab, and studies will be done bonded to Timepix4 ASICs. The candidate will contribute to the Timepix4 telescope test-beam campaign and participate in the project to design a future radiation hard sensor with internal gain.

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
