The Department of Physics and Astronomy, Aarhus University, Denmark ( has two immediate openings for postdoctoral fellows on the ALPHA antihydrogen experiment at CERN, Geneva (

Starting Date and Period
The position is for 2 years and is available from 1 April or as soon as possible.

Job description and your profile
ALPHA conducts precision measurements on atoms of antihydrogen in order to test fundamental symmetries. We seek highly motivated candidates to contribute to our program of spectroscopic studies of trapped antihydrogen atoms. Preference will be given to candidates with experience in precision laser spectroscopy, ion trapping and non-neutral plasmas, atom trapping, or closely related disciplines. Experience with stabilized lasers, frequency metrology, superconducting magnets, cryogenic handling, ultra-high vacuum systems, and position sensitive particle detection will also be valued. The fellows will be employed by Aarhus University but permanently stationed at CERN in Geneva. The initial appointment will be for two years. ALPHA postdocs are expected to contribute to all aspects of the experiment, including experimental shift work, which takes place 24 hours per day during the operating period of the Antiproton Decelerator. The successful candidates will work under the direct supervision of the ALPHA Spokesperson, Professor Jeffrey Hangst. These positions are funded by a grant from the Carlsberg Foundation.

Who we are
The ALPHA Collaboration at CERN is the only group in the world able to study the properties of atoms of antihydrogen, the antimatter equivalent of hydrogen.

Place of Work
The place of work is CERN, CH-1211 Geneva 23, Switzerland and the area of employment is Aarhus University with related departments, stationed at CERN.

Contact Information
Further information can be obtained from Professor Jeffrey Hangst, Department of Physics and Astronomy, Aarhus University, Ny Munkegade 120, DK-8000 Aarhus C / CERN, CH-1211 Geneva 23, Switzerland

Application procedure
Shortlisting is used. This means that after the deadline for applications – and with the assistance from the assessment committee chairman, and the appointment committee if necessary, – the head of department selects the candidates to be evaluated. All applicants will be notified whether or not their applications have been sent to an expert assessment committee for evaluation. The selected applicants will be informed about the composition of the committee, and each applicant is given the opportunity to comment on the part of the assessment that concerns him/her self. Once the recruitment process is completed a final letter of rejection is sent to the deselected applicants, including the main considerations emphasized during the selection process.

Formalities and salary range
Natural Sciences refers to the Ministerial Order on the Appointment of Academic Staff at Danish Universities under the Danish Ministry of Science, Technology and Innovation. (

The application must be in English and include a curriculum vitae, degree certificate, a complete list of publications, a statement of future research plans and information about research activities, teaching portfolio and verified information on previous teaching experience (if any). Guidelines for applicants can be found here.

Appointment shall be in accordance with the collective labour agreement between the Danish Ministry of Finance and the Danish Confederation of Professional Associations. Further information on qualification requirements and job content may be found in the Memorandum on Job Structure for Academic Staff at Danish Universities. (…)

Salary depends on seniority as agreed between the Danish Ministry of Finance and the Confederation of Professional Associations.

All interested candidates are encouraged to apply, regardless of their personal background. Research activities will be evaluated in relation to actual research time. Thus, we encourage applicants to specify periods of leave without research activities, in order to be able to subtract these periods from the span of the scientific career during the evaluation of scientific productivity.

Aarhus University offers a broad variety of services for international researchers and accompanying families, including relocation service and career counselling to expat partners. Read more here. ( Please find more information about entering and working in Denmark here. (
