Introduction

As an applied physicist specialised in particle detectors, you will join the Experimental Physics (EP) department, specifically the CERN Detector Group of the ATLAS experiment, a general purpose detector exploiting the unique physics potential of the LHC’s new energy domain.
The Calorimeter section of the Detector Group has a leading role in the operation of the Liquid Argon (LAr) Calorimeter, the commissioning of its Phase-1 upgrade as well as new construction efforts for HL-LHC. CERN, Take part!

Specifically, the responsibilities within the LAr calorimeter project of ATLAS, mainly are:

• The installation and commissioning of the LAr Calorimeter with its legacy precision electronics as well as the new Phase-1 upgrade electronics.
• The operation of the LAr calorimeter, specially its electronics and associated software and firmware, with new components leading into the Hardware First Level Trigger for ATLAS during Run-3.
• The on-site preparations for the Phase-2 Upgrade of the LAr electronics at CERN as host lab and in the ATLAS cavern.

Functions

You will:

• Take a leading role in the commissioning and operation of the LAr calorimeter. This includes the supervision of a CERN based team of technicians, students and scientists covering all aspects of the LAr calorimeter operation.
• Coordinate the efforts at CERN for all tests, including reception of deliverables and system tests, needed for the construction of the new LAr electronics for HL-LHC assisting the LAr community at large.
• Contribute to the simulation, design and development efforts in the context of CERN's R&D activities related to Calorimeters for future detectors.

In due time you will be one of the leading physicists within the team for the installation, commissioning and operation of the upgraded LAr Calorimeter.

PhD or equivalent relevant experience in the field of in physics with specialisation in particle detectors or a related field.

Experience:

• Proven post-doctoral experience in the development and operation of particle physics detectors in general and calorimeters in particular.
• Demonstrated experience with carrying out particle detector data analysis especially in terms of detector operation and performance.
• Hands on experience with hardware and software for detectors, detector control and readout.
• Proven experience in coordinating multi-disciplinary teams of physicists, engineers and technicians.
• Demonstrated experience in developing data acquisition, data handling and analysis for detector and electronics tests.

Technical competencies:

• Knowledge and application of calorimetry methods and techniques
• Assembly and integration of detectors
• Simulation, design and development of (parts of) detectors
• Analysis and optimization of detector performance
• Development of data acquisition, data handling and analysis for detector operation and readout

Behavioural competencies:

• Working in teams: cooperating constructively with others in the pursuit of team goals; balancing personal goals with team goals; working well in groups and readily fitting into a team; participating fully and taking an active role in team activities.
• Achieving results: dividing extensive work / projects into manageable sub-tasks with clearly defined milestones; defining clear objectives, milestones and deliverables before initiating work/ project.
• Managing self: demonstrating a receptive approach to feedback; being open to criticism and reconsidering position accordingly; remaining objective, focussed and productive in a stressful environment; focusing on solutions rather than problems.
• Communicating effectively: delivering presentations in a structured and clear way; adjusting style and content to the audience; responding calmly and confidently to questions; leveraging support networks across the Organization.
• Solving problems: assimilating large quantities of information, identifying key issues and formulating conclusions clearly and concisely; recognizing what is essential; discriminating between important and peripheral information and being able to see the whole picture.

Language skills:

• English: spoken and written. Ability to draw-up technical specifications and/or scientific reports and to make oral presentations.
• French: willingness to learn the language 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 23.09.2021 at 12:00 pm CET (midday)
