Target and Ion Source Physicist (SY-STI-RBS-2024-97-LD)

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.

Introduction

Are you a qualified and highly motivated physicist with experience in the design and operation of targets and ion sources for Radioactive Ion Beams production? Join a diverse team of technicians, engineers and scientists and play a leading role in the production and development of target and ion source units delivering radioactive ion beams for the ISOLDE facility.

ISOLDE is a leading Radioactive Ion Beams facility with the capability of making 1000 isotopes of 75 elements available to an international community of about 1000 users. MEDICIS is a facility successfully exploiting isotope mass separation techniques to deliver non-conventional radionuclides to partner institutes performing research in the rising field of targeted therapies in nuclear medicine.

You will join the Accelerator Systems Department (SY), which is responsible for the beam-related technical systems of the CERN accelerators. The SY teams design, build and operate equipment systems in all CERN accelerators, and are engaged in ambitious forward-looking R&D programmes.

The Sources, Targets and Interactions Group (STI) in the Systems Department (SY) has a broad expertise on the interaction of beams with matter and applies its know-how to a large spectrum of activities including particle production, beam intercepting devices, studies on beam-matter interaction and nuclear engineering.

You will join the Radioactive Beam Sources Section (RBS), responsible for the coordination of the ISOLDE and MEDICIS facilities as well as for the fabrication of several systems including the Target and Ion Source Units, dedicated to the production of radioactive ion beams.

Functions

As Target and Ion Source Physicist, you will take up the role of lead scientist for the manufacturing and development of targets and ion sources assemblies dedicated to Radioactive Ion Beams production:

You will:

• Organize the planning and resources to produce about 40 target units per year, according to the ISOLDE and MEDICIS physic’s schedule;
• Characterize and document the performance and radionuclides production rate of all target units;
• Review experiment proposals and provide input and feedback to the relevant technical and scientific committees with regards to ion beam production and techniques;
• Lead the target development program for the enhancement of ion beam production and quality and initiate innovative ideas for the production of new ion beams;
• Supervise students and associates for R&D studies and support to operation;
• Collaborate on R&D activities within CERN (including project management and supervisory activities) and to international collaborations;
• Contribute to the ISOLDE improvement program and develop targets compatible with higher beam power.

Experience:

Required experience in:

• The field of targets and ion sources development for the production of Radioactive Ion Beams (RIBs);
• Material development programs such as release properties of isotopes and compounds under extreme conditions;
• Isotope mass separation (ISOL) technique and operation of related facilities or in mass spectroscopy, ion beam acceleration and transport, beam manipulation as well as Radioactive Ion Beams detection or characterization.

Technical competencies:

• Knowledge and application of beam production techniques;
• Simulation, design and development of beam sources;
• Knowledge of radiation effects and ageing of materials;
• Analysis and optimization of accelerator performance;
• Development, review of plans for physics and related technologies R&D programmes.

Behavioural competencies:

• Demonstrating accountability: working conscientiously and reliably; delivering on promises; using openness and honesty to interact constructively with others; using power or position in the interest of all.
• Communicating effectively: expressing opinions, ideas and suggestions with conviction and in a logical/structured manner; keeping to the point; giving praise and providing honest and constructive feedback.
• Achieving results: delivering high quality work on time and fulfilling expectations; objectively assessing and monitoring own work; regularly reporting on progress and advising of any changes in schedule or priorities; having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.
• Building relationships: showing appreciation for the ideas and contributions of others and encourages others to express their views, even if controversial; demonstrating an appropriate sense of humour; relating well to all people regardless of category/level within the Organization.
• Working in teams: building and maintaining constructive and effective work relationships; working well in groups and readily fitting into a team; participating fully and taking an active role in team activities;sharing and letting others participate in own work/project; encouraging team development.

Language skills:

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.

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 23:59 CEST 7th July 2024.
