Vacancies and Topics
The Institute of Applied Physics (IAP) of the Goethe University Frankfurt invites applications for two positions of Postdoctoral researchers (m/f/d)
The positions are open from now and will be limited for three years. The salary grade is based on the job characteristics of the collective agreement (TV-G-U) applicable to Goethe University.
IAP is involved at the accelerator facility GSI-Darmstadt from the beginning, as well as in the current project FAIR. Within the announced positions the ion linear accelerator Unilac should be optimized for its future task as FAIR high current ion injector. This goal can only be reached after several limitations will have overcome – from the ion source down to synchrotron injection.
The first position will focus activities on beam simulations, beam measurements, development and integration of diagnostic tools, layout of new elements along the beam transport systems. The second position will perform measurements and investigation on existing RF cavities to improve their performance. Additionally, the longitudinal beam dynamics and optional improvements by added buncher cavities should be studied.
You have a university degree as a master in physics or electrotechnics and a doctoral degree in the field of accelerators, preferably in linear accelerators, cavity development, beam dynamics or beam diagnostics. Please send your application before 18.06.2021 by email (attaching in a single pdf document) and including a letter outlining your suitability for the post, a detailed CV and a copy of your PhD-thesis to Prof. Dr. U. Ratzinger, email@example.com
The Institute of Applied Physics of the Goethe University Frankfurt invites applications for the position of a Post-doctoral researcher (m/f/d)
The position is open from now and will be limited to a period of 3 years. The salary grade is based on the job characteristics of the collective agreement (TV-G-U) applicable to Goethe University.
The research fields are accelerator physics and utilization of Machine Learning and Artificial Intelligence concepts.
FAIR (Facility for Antiproton and Ion Research) is a flagship project for hadron, nuclear, and heavy-ion research in Europe for the next decades, and the Helmholtz Research Academy Hesse for FAIR (HFHF) is on the front-line to support the scientific and technological excellence. This project aims to study the challenges of high intensity and high brightness facilities as a full complex system by applying novel emerging fields such as machine learning (ML) / artificial intelligence (AI). These techniques will be explored to their full potential for overcoming the bottleneck of existing facilities and future intensity frontiers.
FAIR phase 0 requires complex beam manipulations in the GSI storage rings, which unavoidably sees beam control affected by beam physics effects generated by extreme beams. Hence, it is mandatory to develop an efficient interface to the FAIR control which is similar to the CERN LHC control (LSA and FESA). This task is envisioned considering all the beam manipulations and storage ring facilities as a full complex system, namely the linear and nonlinear beam dynamics of injection/deceleration/storage/extraction is investigated including all details of magnets and beam cooling systems. The optimization is planned to be approached by making use of advanced algorithms using AI techniques.
