Introduction

The Engineering Department (EN) pushes forward the limits of technology to provide innovative research tools to the physics and engineering worldwide community. Within Sources, Targets and Interactions Group (STI) of the EN department, you will join the Beam Machine Interactions (BMI) Section, which is responsible for the development and  maintenance of the FLUKA Monte Carlo code and for providing formal training and support to its users, including in particular in the accelerator community and to the experiments worldwide. The section also performs beam-machine interaction studies for all CERN accelerators, and FLUKA calculations for different applications, including conceptual 
design of beam intercepting devices, new target areas, medical applications, etc…  

Are you excited to join the world leading particle physics research laboratory? Then join CERN and take part! 

Functions

As Physicist/Engineer in the Beam Machine Interactions Section, you will initially: 

• Contribute to improve and refine the atomic and nuclear physics models used in FLUKA and required for the applications to CERN Accelerator problems; 
• As part of the FLUKA team, assist the other members in the application of the code for the purposes of CERN accelerators, especially the Large Hadron Collider (LHC), the injector chain, their future upgrade projects, and the other future CERN projects (FCC, muon collider, etc..);
• Help to maintain and regularly distribute worldwide the FLUKA code; 
• Contribute to the development of a new code structure and interfaces with other Monte Carlo codes. 

In the longer term the successful candidate is expected to: 

• Contribute to the organization and management of the code development at CERN as well as internationally; 
• Assure the functionality of the FLUKA code with respect to CERN’s needs. 

Master's degree or equivalent relevant experience in the field of physics or nuclear engineering or a related field. 

Experience:

The experience required for this post is: 

• Proven experience within particle and nuclear physics;
• Experience in the simulation of radiation matter interaction, in particular by the development and application of Monte Carlo techniques;
• Experience in computer programming and simulation tool implementation, with any of Fortran, C, C++ and Python.

Would be considered a plus: 

• Expertise in the use of the FLUKA code or other multipurpose Monte Carlo code;
• Knowledge of experimental high-energy particle physics, and of the principles of accelerator physics;
• Specific experience in simulation studies addressing research or medical accelerator problems.

Technical competencies:

• Knowledge and application of nuclear reactions and structure: including nuclear reaction modelling
• Knowledge and application of electromagnetic radiation propagation and interaction with matter
• Knowledge and application of computational and mathematical physics
• Simulation of radiation environments
• Knowledge and application of motions and interactions of neutrons with materials (neutronics)

Behavioural competencies:

• Working in Teams: building and maintaining constructive and effective work relationships Contributing to promoting a positive atmosphere in the team through an optimistic and constructive attitude; addressing issues Sharing and letting others participate in own work/project; encouraging team development
• Demonstrating Flexibility: actively participating in the implementation of new processes and technologies Demonstrating willingness to alter views when presented with new information Being able to demonstrate flexibility whilst abiding by all applicable rules
• Achieving Results: defining clear objectives, milestones and deliverables before initiating work/ project Objectively assessing and monitoring own work; regularly reporting on progress and advising of any changes in schedule or priorities
• Solving Problems: assimilating large quantities of information, identifying key issues and formulating conclusions clearly and concisely. Being open to original ideas and creative options by which to address issues; continually driving change by seeking new ways to improve outcomes
• Learning and Sharing Knowledge: creating or participating in forums to exchange experience, comparing techniques and learn from others Proposing ways to improve or streamline existing procedures, processes and methodologies.

Language skills:

Spoken and written English or French: ability to draw-up technical specifications and/or scientific reports and to make oral presentations in at least one of the two languages and an undertaking to acquire the other rapidly.

Eligibility and closing date:

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success. We welcome applications from all Member States and Associate Member States.

This vacancy will be filled as soon as possible, and applications should normally reach us no later than 31.10.2020.
