Power System Physicist/Engineer for the CMS HGCAL

As Power System Physicist/Engineer for the CMS High-Granularity Calorimeter (HGCAL), you will play a key role in the development, integration, testing and commissioning of the power systems for one of the most innovative particle detectors ever conceived. You will contribute to procurement, testing, integration, and performance assessment of power systems in a multinational team.

Responsibilities

• Follow the procurement of the power supplies (Low Voltage and Bias Voltage, totalling several MCHF), including carrying out acceptance and stress tests on the delivered units.
• Support the commissioning of these power systems during the mass assembly and testing phases of HGCAL.
• Work with physicists and engineers to evaluate the performance of HGCAL in relation to its power systems and to develop and implement mitigation strategies where possible and necessary, first on the surface and subsequently when HGCAL is installed in CMS, 100 metres underground.
• Work with the HGCAL and central CMS Technical Coordination teams to oversee the installation and testing of the power systems underground in the “Service” and “Experimental” caverns.
• Oversee cable installation, in-situ connectorisation where needed, testing and commissioning, and the integration of the power system into the HGCAL and CMS safety and monitoring systems.

Requirements

• Master's Degree or PhD or equivalent relevant experience in the field of Applied Physics, Electrical Engineering or a related field.
• Strong track record in testing, operating and debugging power systems for complex devices, such as particle detectors used in high-energy physics experiments.
• Experience with silicon- and/or scintillator-based particle detectors would be an advantage.
• Experience with large-scale procurement of electronic systems, such as power supplies.
• Ability to work successfully and efficiently within multinational, multicultural teams of engineers, scientists and technicians would be an advantage.
• A valid driving licence.
• Willingness to work in Radiation Areas.
• Ability to perform interventions in underground installations.
• Availability to work during nights, Sundays and official holidays, when required by the needs of the Organization.
