Postdoctoral Scientist (f/m) for Superconducting RF Cavity Development

Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) operates two large facilities for materials research: the neutron source BER II and the synchrotron source BESSY II, which provide deep insights into the structure of materials and the processes within complex systems. Each year around 3,000 scientists are using the HZB infrastructures. One important focus of HZB research is thin film photovoltaics and solar fuels. HZB is a member of the Helmholtz Association.

Postdoctoral Scientist (f/m)
for Superconducting RF Cavity Development

The Helmholtz-Zentrum Berlin für Materialien und Energie GmbH (HZB) operates one of the world's most advanced Synchrotron Light Sources (BESSY II) in the VUV to soft x-ray range. With its accelerator staff of about 100 employees, HZB strives to continuously improve its existing accelerators, and to develop novel concepts for future applications.

With these goals in mind, HZB has secured funding for the BERLinPro project, a 100 mA, low emittance Energy Recovery Linac (ERL) designed to develop the technology and expertise required for future high-current CW ERLs. The project is embedded in a framework of international collaborations. Beyond this, HZB is heavily involved in the Helmholtz Association's "Accelerator Research and Development" SRF Program (ARD) to develop CW SRF systems for next-generation accelerators. In this context the SRF Institute of Science and Technology is seeking an excellent candidate for the following position:

Post-doctoral Position in Superconducting RF Cavity Development

The ideal candidate will have experience working with SRF cavities, a strong background in experimental physics, engineering, or similar field. As part of the BERLinPro team the candidate will be responsible for multiple aspects of SRF cryomodule development which may include higher order mode absorber design and development, SRF cavity testing, as well SRF infrastructure development for basic R&D. The latter may include installation and commissioning of vertical testing dewars as well as implementation of appropriate cavity testing diagnostics such as cavity thermometry measurements, second sound quench detection, and internal optical inspection of SRF cavities. The candidate may also participate in CW SRF R&D such as Q0 improvement techniques or studies of thin-film coatings for use in next generation SRF cavities. This position requires a self-starter who can work independently.

Requirements:

PhD in Physics or closely related field in the last 5 years
Experience with SRF cavities and auxiliary components
Experience with LabVIEW is desirable
Fluency in English, both written and spoken

Andrew Burrill, Tel.: 030/8062-17917

The Employment contract is limited to 3 years.
The salary is based on the German Tarifvertrag für den öffentlichen Dienst (TVöD).
Application deadline: March 14th, 2014

As HZB endeavors to increase the number of women working in the scientific field, women are especially encouraged to apply. Applicants with disabilities will be given preference to others of equal qualification.

Applicants should send their application quoting Reference No. G 2014/2 to
the Helmholtz-Zentrum Berlin für Materialien und Energie GmbH, Abteilung Personal und
Soziales, Hahn-Meitner-Platz 1, 14109 Berlin (email: bewerbung@helmholtz-berlin.de).
