Offer Description

Company Description

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 .

Job Description

Introduction

Are you interested in the challenges of designing, operating, maintaining, and developing complex gas distribution and recuperation systems for particle physics detectors of CERN's Large Hadron Collider? Do you want to participate in the development of the next generation gas plants to cope with the most demanding requirements of future experiments at CERN? If you are passionate about groundbreaking research and thrive in a dynamic, collaborative environment, we would love to hear from you!

You will join:

• The Experimental Physics (EP) Department, which carries out basic research in the field of experimental particle physics in a stimulating scientific atmosphere, standing as an important reference for the physics community. It also contributes to the education and training of young scientists.
• The Detector Technologies (DT) Group, participating in the development, construction, operation, and maintenance of particle detectors and their technical infrastructure for the LHC experiments and several other experiments at CERN.
• The Fluidic Systems Section, which is in charge of the design, construction, operation, and maintenance of fluidic systems (gas and cooling) for detectors in CERN experiments. It has also a mandate to perform selective R&D in areas relevant to novel detector thermal management, gas recuperation plants, and for the upgrade of the existing systems in view of higher detector performances and sustainable operation.

As an Applied Physicist in the Fluidic Systems Section, you will:

• Participate in the design and construction of new gas distribution and recuperation systems for particle physics detectors, evaluating the needed performances with respect to the detector operation.
• Participate in the maintenance and operation of about 30 existing gas systems at CERN.
• Contribute to the R&D program of the gas team, focused on the search and validation of new gas mixtures, the development of new gas systems to enhance the detector performances and reduce the Global Warming Potential (GWP).
• Assume a leading role in the design of Process Control functional analysis, proposing innovative solutions and operating methods in agreement with the experiments.
• Take responsibility for the configuration, programming, and use of Supervisory Control and Data Acquisition (SCADA) systems (Win CC-OA), PLC (Schneider and Siemens), and fieldbus (Profibus and CANbus).

Qualifications

Master's degree or equivalent relevant experience in the field of Physics or a related field.

Experience:

• Solid knowledge about particle physics detectors, their operation and maintenance.
• Experience in the design, operation, and performance evaluation of gas distribution and recuperation systems for particle physics detectors.
• Proven understanding of effects related to gas mixture composition for particle detectors.
• Design, commissioning, and operation of PLC based control systems for complex processes with experience of both PLC and SCADA systems, including related documentation for user requirements, functional analysis, quality assurance etc.
• Experience in scientific publication and presentation.
• Knowledge and application of gas based particle detection technologies.
• Design, construction, operation, and maintenance of detector gas distribution systems.
• Functional analysis of control systems.
• Configuration and implementation of industrial data-acquisition, monitoring, and control systems: (PLC, SCADA).
• Achieving Results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.
• Learning and Sharing Knowledge: sharing knowledge and expertise freely and willingly with others; coaching others to ensure knowledge transfer.
• Demonstrating Accountability: working conscientiously and reliably; delivering on promises.
• Solving Problems: finding the information needed to solve problems; making objective judgments based on all the facts available.
• Working in Teams: supporting and acting in accordance with team decisions; accepting joint responsibility for team successes and shortcomings.

Spoken and written English or French: ability to understand and speak the other language in professional contexts. Ability to draw-up technical specifications and/or scientific reports and to make oral presentations in at least one of the two languages.

Languages:

• ENGLISH: Good
• FRENCH: Good
