Job Description
Job Posting Organization:
The job posting organization is CERN, the European Organization for Nuclear Research, which was established in 195
  • CERN is one of the world's largest and most respected centers for scientific research, particularly in the field of particle physics. It employs over 2,500 staff members and has a diverse workforce that includes physicists, engineers, technicians, and administrative personnel from around the globe. CERN operates in multiple countries, with its main facility located in Geneva, Switzerland, and collaborations extending to numerous institutions worldwide. The organization is dedicated to pushing the boundaries of knowledge and technology, fostering an environment of innovation and collaboration among its members. CERN's mission is to uncover the fundamental constituents of matter and the forces that govern their interactions, contributing significantly to our understanding of the universe.

Job Overview:
The position of Early Career Stage Researcher is part of the Marie Sklodowska-Curie Actions, which aim to train young researchers and build the careers of future leaders in research and industry. The selected candidate will engage in advanced development work related to ion beam technologies and the production and characterization of radioactive anions at CERN's ISOLDE facility. This role offers a unique opportunity to work on cutting-edge research projects that bridge fundamental science and practical applications. The researcher will also spend time at the University of Gothenburg, where they will receive training in laser and ion beam technologies, participate in research on photodetachment of negative ions, and take relevant courses. The position is designed for recent graduates or those with equivalent qualifications who are eager to contribute to significant scientific advancements.

Duties and Responsibilities:
The duties and responsibilities of the Early Career Stage Researcher include:
  • Conducting research on ion beam developments and techniques for producing and characterizing radioactive anions at CERN's ISOLDE facility.
  • Developing methods to efficiently produce negative ions from radioactive species in the offline laboratory.
  • Participating in online experiments to characterize these negative ions.
  • Collaborating with the Laser spectroscopy research group at the University of Gothenburg, led by Professor Dag Hanstorp.
  • Taking courses and receiving training in laser and ion beam technologies.
  • Engaging in research activities related to photodetachment of negative ions.
  • Contributing to the overall objectives of the PANIONS Doctoral Network and participating in training activities, conferences, and collaborative projects.
  • Submitting two identical applications to CERN and the University of Gothenburg, including required documentation such as a personal letter, CV, and references.
  • Participating in interviews and contributing to the network's research culture.

Required Qualifications:
To qualify for this position, candidates must meet the following requirements:
  • Possession of a university degree (MSc) or equivalent qualification that allows for enrollment in a doctorate program. Candidates currently studying for their MSc may apply if they will complete their degree before June 202
  • Candidates must be in the first four years of their full-time research career after obtaining their degree and must not hold a PhD.
  • Candidates must not have held a contract with CERN at more than 50% presence for more than 12 months in the last three years at the time of recruitment.
  • Knowledge in one or more relevant fields such as ion beam physics, ion sources, atomic and molecular physics, nuclear physics, laser technology, electronics, programming, and data collection.
  • Strong motivation and the ability to work independently as well as collaboratively within a large research project.
  • Candidates of any nationality are encouraged to apply.
  • Proficiency in English is mandatory.

Educational Background:
Candidates must possess a university degree (MSc) or a corresponding qualification that allows them to embark on a doctorate. Those who are currently studying for their MSc may apply if they will finish their degree before June 202
  • However, the PANIONS contract cannot commence until the MSc is completed. This educational background is essential for the candidate to engage in the advanced research and training activities associated with the position.

Experience:
The position requires candidates to be in the early stages of their research career, specifically within the first four years after obtaining their degree. Candidates must not hold a PhD and should have relevant experience or knowledge in fields related to ion beam physics, atomic and molecular physics, or other related disciplines. This early-career focus is designed to cultivate new talent in the field of research and provide them with the necessary skills and experience to advance their careers.

Languages:
Proficiency in English is mandatory for this position, as it is the primary language of communication within the research environment. While English is the required language, knowledge of additional languages may be considered beneficial but is not explicitly stated as a requirement.

Additional Notes:
The position offers an employment contract for 36 months under the conditions of the Marie Sklodowska-Curie Actions, followed by a new contract from the University of Gothenburg for an additional 12 months to complete the PhD according to university standards. The position includes a monthly stipend of 5266 Swiss Francs net, 30 days of paid leave per year, and coverage by CERN's comprehensive health insurance scheme for the researcher and their family. Additional benefits include family allowances, a relocation package, and opportunities for on-the-job and formal training, including language classes.
