PhD position in the Time-of-Flight Electron Energy Loss Spectroscopy project

Four-year PhD position in the Time-of-Flight Electron Energy Loss Spectroscopy project: advanced EELS for unravelling the enigmas of strongly correlated electron systems.
Faculteit Technische Natuurkunde



Recent developments in RF-cavity-based Ultrafast Electron Microscopy (UEM) at TU/e  CQT group [1,2] have led to a new form of Electron Energy Loss Spectroscopy (EELS), based on a Time-of-Flight  (ToF) scheme combined with longitudinal phase space manipulation of ultrashort electron bunches [3,4]. Ultimately, the new ToF EELS method promises a unique few-10 meV energy resolution at 30 keV, combined with few ps temporal resolution. This would enable the detection of low-lying, short-lived, phonon-like excitations in strongly correlated electron systems. The CQT group has teamed up with condensed matter physicist Dr. C. Flipse of the TU/e group Molecular Material and Nanosystems (M2N) to apply this new technique for fascinating solid state systems such as Hi-Tc superconductors and strange metals. The PhD position is part of the NWO-PR project Advanced EELS for unravelling the enigmas of strongly correlated electron systems.

Project description

The PhD position will be part of a project team, consisting of beam physicists, condensed matter physicists and technicians. The PhD student we are looking for will design, build and test the ToF EELS setup together with a postdoc experienced in beam physics. In the third year of the project the student will perform the first time-resolved EELS demonstration experiment in collaboration with a postdoc experienced in condensed matter physics. We are looking for an experimental physicist or physics engineer, preferably with experience in beam physics and a strong interest in advanced materials science.


The work will be mostly performed in the Coherence and Quantum Technology group of the Department of Applied Physics on the campus of Eindhoven University of Technology. The research in the CQT group is centered on coherence in ensembles of atoms, ions, electrons and photons. We combine expertise from plasma physics, AMO physics and particle beam physics to investigate new areas and applications of these techniques, either to future technologies or to other areas in physics.

We are looking for talented and motivated candidates with a Master degree in experimental Physics or a related field. A background in beam physics is highly desirable. Candidates must also have good communication skills, including fluency in written and spoken English. You must be able to tackle different aspects of a complex problem with a great deal of independence but also to collaborate in good team spirit with other members of the team. Important selection criteria are high grades and an advanced scientific background including a Master thesis project at the level of major research universities.


We offer a challenging research project in an ambitious research group through a fixed-term appointment for a period of 4 years. The research is intended to lead to the attainment of a PhD degree. As an employee of the university you will receive a competitive salary as well as excellent employment conditions. The salary starts at € 2222,- per month (gross) in the first year, increasing up to € 2840,- per month (gross) in the last year. Moreover, an 8% holiday allowance and 8.3% end-of-year allowance is provided annually. Assistance for finding accommodation is available. The university offers an attractive package of fringe benefits such as excellent technical infrastructure, child care, savings schemes, and excellent sports facilities. TU/e also provides opportunities for personal development by offering every PhD student a series of courses in the PROOF program as an addition to your scientific education.
