德国柏林亥姆霍兹材料与能源中心招聘超导空腔共振器开发博士后

Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) operates two large research infrastructures, the neutron source BER II and the photon source BESSY II. These facilities serve an international user community from many scientific disciplines, hosting more than 3000 external users per year. HZB staff performs accelerator research, develops science-driven designs of new instruments and develops novel methods using synchrotron radiation in the VUV and soft-X-ray regime primarily for materials and energy research. Materials and energy research at HZB focuses on photovoltaics and solar fuel generation, as well as on fundamental aspects of energy storage and energy efficiency.

The Scientific Division Large Scale Facilities is seeking for the Institute SRF – Science and Technology a

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 SRF cavity testing and implementation of diagnostics to aid in the characterization of SRF cavities in both the vertical and horizontal RF tests. This may include cavity thermometry, second sound quench detection, field emission mapping as well as the development of a novel internal internal inspection system. The candidate may also participate in CW SRF R&D such as Q0 improvement program 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

The Employment contract is limited to 3 years.

The salary is based on the German Tarifvertrag für den öffentlichen Dienst (TVöD).
