Om jobbet

Lund University was founded in 1666 and is repeatedly ranked among the world’s top 100 universities. The University has 40 000 students and 7 600 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

MAX IV is a Swedish national large-scale research laboratory hosted by Lund University. It provides scientists from Sweden as well as internationally, with state-of-the-art instrumentation for research in areas such as engineering, physics, structural biology, chemistry and nanotechnology. Fully developed it will receive more than 2 000 scientists annually, conducting ground-breaking experiments in materials and life sciences using the brilliant X-ray light. As a national laboratory, MAX IV is operated in agreement with governmental regulations, and in compliance with major funders such as the Swedish Research Council (VR) and the Wallenberg Foundation. 250 people are currently employed at MAX IV Laboratory, and 16 beamlines are funded. The facility is in a ramp-up phase with 3 beamlines now receiving users and 13 more scheduled to be commissioned and built to receive users within the next few years. The facility is dimensioned for 25-28 beamlines.

The Low-Density Matter (LDM) team at MAX IV is engaged in activities related to gas-phase and liquid phase research.

We are now looking for an enthusiastic and skilled postdoctoral researcher with expertise in LDM physics to participate in various projects managed by the LDM team at MAX IV.

In addition to participating in different aspects of design, building and commissioning of various pieces of equipment, the candidate is also expected to participate in user support when the LDM instrumentation is in use at one of MAX IV’s LDM-relevant beamlines.

Description of the LDM-team

MAX IV currently has 5 LDM-relevant beamlines: FlexPES, FinEstBeAMS, FemtoMAX, VERITAS and RIXS @ SPECIES. Each of these beamlines will either be regularly engaged in Low Density Matter activities, or, it will be capable of accommodating mobile LDM equipment, or, it has the possibility of allowing some form of LDM measurements at one of its own end stations.

A mobile modular end station for LDM research is currently under development at MAX IV. The ICE end station will provide the MAX IV Low Density Matter community with instrumentation to enable high-resolution multi-coincidence and momentum imaging spectroscopies.

The current scope of the ICE project (which was decided upon in close-collaboration with our user community), foresees the availability of two types of multi-coincidence spectrometers – a reaction microscope spectrometer (REMI) and a Magnetic Bottle Electron Spectrometer (MBES).

Commissioning of the REMI with soft x-ray radiation is planned for the autumn of 2019. The MBES is currently in the design stage. Further projects involving potential new end stations for Low Density Matter research are also being pursued.

Job description

The work tasks of the postdoc in the LDM-team include, but are not limited to, the following:

- Participate in the commissioning, maintenance and operation of various pieces of LDM equipment. This equipment includes the ICE end station and some sample delivery systems (molecular jet/cluster source and liquid jet sources)
- Provide user support on LDM equipment
- Participate in the design or build-up of more LDM relevant equipment when the need arises

The candidate will have the possibility to apply for beamtimes at MAX IV to conduct his or her own research using the LDM equipment at MAX IV or to apply for beamtimes at other facilities. Therefore, it is expected that the candidate will have a strong vision with regards to various research projects that they would like to pursue whilst employed in this position.


- The candidate must hold a PhD in physics, solid state chemistry or another relevant field (please see “Important information” below)
- Documented experience in the use of ultra-high vacuum equipment
- Documented experience in at least one relevant multi-coincident technique
- Experience in working at a large-scale scientific facility (example synchrotron, FEL, etc) as either a user or as a member of staff
- Experience in using/maintaining a relevant sample delivery system (example molecular beam sources, cluster sources or liquid jet source)
- Experience in the handling of gases
- The ability to work in a team and good communication skills are extremely important for this position
- The successful candidate is expected to have the ability to work independently in the lab, as well as part of a team. This position is foreseen to involve collaboration with the LDM staff at the various beamlines

The candidate must also have a good command of the English language in order to effectively communicate with users and staff at the laboratory.

Additionally, meriting qualifications

- Experience in other spectroscopic techniques (ex. Photoelectron spectroscopy)
- Experience in mechanical engineering and competence in using SolidWorks
- Experience in advanced data analysis and programming (especially python-based)
- Experience in the use of ion optics simulation programs such as SIMION
- Experience in using laser systems and pump-probe techniques

Important information: This is a post-doctoral position for two years. Appointment to a post-doctoral position requires that the doctoral degree or equivalent is completed no more than three years before the last date for applications. Under special circumstances, the doctoral degree may have been completed earlier.

We are planning to start the first round of interviews in the second half of January 2020.

On call services may apply in the future.

Lund University welcomes applicants with diverse backgrounds and experiences. We regard gender equality and diversity as a strength and an asset. We kindly decline all sales and marketing contacts.
