Electronics Technician

As an Electronics Control Technician, you will support the installation, upgrade, and maintenance of the vacuum control systems that protect and monitor CERN’s accelerators. You will work both autonomously and within a multidisciplinary team of technicians and engineers, following established procedures and quality assurance standards. The role involves frequent interaction with contractors and CERN groups involved in signal cabling, IT networks, and electrical power infrastructure.
You will contribute directly to the large-scale upgrade of the vacuum control systems for the High-Luminosity LHC (HL-LHC), carrying out hands-on technical activities in workshops, surface buildings, and accelerator tunnels.
The TE-VSC-ICM section is responsible for all vacuum control systems, vacuum interlocks, and monitoring tools across CERN’s accelerators and detectors. During Long Shutdown 3 (LS3), starting mid-2026 and lasting around three years, these systems for the LHC will undergo major modernisation. This is work you will actively support.

**Your responsibilities**

- Perform reception tests of control equipment and cables in laboratory settings.
- Install and uninstall control equipment and cables in racks and accelerator tunnels.
- Disassemble and reassemble vacuum control systems at LHC Point 1 and Point 5 to accommodate the new HL-LHC layout, including experiments.
- Install radiation-tolerant electronics in all LHC arcs.
- Install new controllers at all LHC points.
- Test and commission control equipment.
- Calibrate controllers and electronics.
- Perform insulation tests on cables.
- Validate measurement chains, interlocks, and alarm systems.
- Produce and update technical documentation.
