Job Description

Your responsibilities

The candidate will investigate the performance of silicon pixel sensors produced for future applications, focusing on spatial and temporal resolution and radiation hardness. The characterisation will be carried out in the lab and in testbeam. Bonding tests will be carried out with Timepix4 ASICS and future prototype ASICs. The candidate will work with ASIC designers at CERN and will develop a readout board capable of characterising the ASIC performance at high rates.

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
