Collimator Systems Engineer (SY-STI-TCD-2025-70-GRAP)

Your responsibilities

As a Collimator Systems Engineer, you will join the Targets, Collimators and Dumps (TCD) Section of the Sources, Targets, and Interactions (STI) Group within the Accelerator Systems (SY) Department. In this role, you will contribute your expertise to the team by overseeing the production of collimators and masks within WP5 of the High-Luminosity LHC Project.

The role involves supporting critical aspects such as procurement, quality assessments, assembly and testing procedures and management of collimators and masks essential for LS3.

This role offers a unique opportunity to contribute to a crucial phase of the HL-LHC Project within WP5. To prosper and grow in this position, you should possess a blend of technical proficiency, project management skills and a proactive approach to problem-solving.

Responsibilities include:

• Overseeing and managing the collimators reception tests, quality checks and assembly activities, ensuring adherence to project timelines and quality standards.
• Providing hands-on support during test campaigns, ensuring a smooth execution and accurate data collection. - Following up with several collimator production activities in industry (in Italy and other Member State countries), including production problems solving. This may involve duty trips.
• Supervising and managing surface activities related to collimators at CERN, ensuring operational efficiency and compliance with safety protocols.
• Documenting installation procedures of collimators in the machine, coordinating with other CERN teams.
• Taking charge of managing technical documentation associated with the production and operation of the collimators, ensuring accuracy, accessibility and compliance with CERN's standards.
• If project schedule allows, participating in the installation of collimators and masks in the machine.
• If required, coordinating contracts with industry partners, overseeing shipment logistics, maintaining inventory records and conducting quality assessments of received components.

The responsibilities outlined above may vary slightly depending on the priorities of the project and how the schedule progresses.

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 http://home.cern.
