Jobs and Positions

Open positions

We are always interested in receiving CV's of enthousiastic young scientists with expertise in our research field, for all levels, from Masters, PhD or PostDoc.

New PhD and Postdoc positions available for research program to solve the Proton Radius Puzzle
We newly acquired funding from FOM/NWO for an integral research program that aims to solve the Proton Radius Puzzle and potentially find clues for new physics. The idea is to perform highly advanced laser precision spectroscopy in four systems: H2, HD+, He+ and He. For this we have several PhD and postdoc positions available from 1 January 2017. You can find the general information about the program here.
For more specific information about the 4 projects involved, you can use the following links:
Project A1 and A2: precision spectroscopy on He+ ions and H2 molecules

PhD and Postdoc positions available due to the ERC Advanced Grant of Kjeld Eikema
Kjeld Eikema was awarded an ERC Advanced Grant for “The Proton Size Puzzle: Testing QED at Extreme Wavelengths”.
There are several PhD (4 year) and Postdoc (2-3 year) positions available. We are looking for enthusiastic and ambitious people; please look here for more information.

PostDoc position: Photoabsorption and dissociation of CH and carbon-based radicals
At LaserLaB VU University Amsterdam we have an opening for a PostDoc working on the spectroscopy of carbon-based molecules in connection to the chemistry of the interstellar medium. Cavity ring-down laser spectroscopy will be used as the method of choice to carry out the investigation, but laser-induced fluorescence and multi-photon ionization may be used as well. Carbon-based radicals will be produced in plasma jet expansions. The project is connected to the long-standing problem of the Diffuse Interstellar Bands. The work is part of a larger consortium of the Dutch Astrochemistry Network with several groups (including 12 young scientists) working in collaboration. Experience with Pusled dye lasers or other laser systems is required.

The Advanced Research Center for Nanolithography (ARCNL) focuses on the fundamental physics involved in current and future key technologies in nanolithography, primarily for the semiconductor industry. ARCNL’s program is intimately connected with the interests of ASML. A significant part of the initial program is devoted to the physics that is central in the generation of high intensities of extreme ultraviolet light and its use in nanolithography. In the course of time, ARCNL’s program will evolve to keep the center at the frontier of research in the area of nanolithography.
