Detector cooling specialist

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 http://home.cern.
Job Description
Introduction

Are you a technical engineer with experience in cooling systems for particle physics detectors? Then seize this opportunity and join CERN's Experimental Physics (EP) Department, where you will take a leading role in the commissioning and operation of the complex cooling systems used in the LHCb experiment.

Functions

The LHCb detector, which has recently undergone a major upgrade, comprises several subsystems with challenging requirements in terms of thermal management. The cooling technologies that are used include evaporative CO2 cooling (with an evaporation temperature of -35° C) as well as a monophase liquid cooling system at -50° C.

As a key member of the LHCb Technical Coordination team (EP-LBO-DO section) you will collaborate closely with detector experts and interface between the relevant CERN cooling groups and LHCb collaborators to:

-support the commissioning and the day-to-day operation of the detector cooling systems in the underground experiment and the associated service infrastructure,
-coordinate maintenance activities, corrective interventions, and consolidation work,
-participate in the LHCb infrastructure and safety stand-by duty service,
-contribute to R&D on cooling technologies for future improvements of the LHCb experiment, taking into account integration, infrastructure, safety and environmental aspects,
-prepare technical specifications and reports,
-design, build and operate surface test facilities.

Qualifications
Bachelor's degree or equivalent relevant experience in the field of mechanical engineering or a related field.

Experience:

-In mathematical modelling of boiling fluids and thermal calculations.
-In the commissioning and operation of detectors and their service systems including the relevant safety aspects.
-In quality assurance processes.

Experience in the following areas would be considered an asset:

-Design and operation of CO2 cooling systems.
-Experience with control and instrumentation.
-Production of electrical and mechanical schematics.
-Production of written reports.

Technical competencies:

-Design, construction, operation and maintenance of detector cooling systems
-Simulation, design and development of infrastructure for detectors or experimental facilities
-Knowledge and application of thermal and/or fluid measurement techniques

Behavioural competencies:

-Working in teams: understanding when teamwork is required to achieve the best results; including others accordingly and sharing information; building and maintaining constructive and effective work relationships,
-Achieving results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind,
-Demonstrating flexibility: adapting quickly and resourcefully to shifting priorities and requirements,
-Communicating effectively: ensuring that information, procedures and decisions are appropriately documented,
-Learning and sharing knowledge: taking steps to expand knowledge in other areas of expertise beyond own field.

Language skills:

Spoken and written English or French: ability to draw up technical texts in one of the two languages, as well as ability to understand and speak the other language in professional contexts.
