PhD Position in Accelerator Physics – Slow Extraction Beam Quality Improvement
GSI Helmholtzzentrum for Heavy Ion Research (www.gsi.de) in Darmstadt, Germany is one of the leading particle accelerator laboratories in fundamental sciences. In the upcoming years, the new FAIR (Facility for Antiproton and Ion Research), a world-leading ion accelerator will be built within an international cooperation.
The department of ‘Beam Instrumentation and Diagnostics’ is responsible for the development, installation and operation of instruments required for the control of the existing facility and the future FAIR accelerators.
GSI in collaboration with Goethe University Frankfurt is offering a PhD position in the field of Applied Physics.
Most experiments at GSI and, in future at FAIR will be served by a slowly extracted beam from the synchrotron with a typical duration of several seconds. This process is very sensitive to fluctuations of the extraction parameters and should be explored and improved.
As a first step of these investigations, the beam fluctuations have to be measured by a fast particle detector based on scintillators and diamond-based sensors. Starting from recently available technologies, these sensors and a performant data acquisition has to be developed and commissioned. Following that, relevant experiments have to be designed and executed at the GSI synchrotron and measurement results have to be analysed. The interpretation of the results should be accompanied by detailed simulations using modern beam dynamics codes taking full non-linear dynamics of the slow extraction into account.
The goal for these investigations is the modelling of the slow extraction process and its improvement according to the requirements of the users. The results will leads to a high scientific recognition not only related to the GSI and FAIR facility, but also from an international community working at comparable improvements.
The candidate will work in the field of high-end technologies, on a relevant and challenging subject, which combines numerous aspects of applied physics and electrical engineering. Practical and theoretical aspects are well balanced.
The candidate will be member of a group, which is world leading in the development of beam sensors and accelerator operation. There will be assistance provided in planning and time schedule for all steps of the thesis in addition to supervision by the competent staff members.
An excellent working atmosphere is offered in a dynamic evolving laboratory, where the ambitious and widely noticed FAIR project is becoming a reality. Introduction to the world wide accelerator community and top level institutes is offered. A part time stay at another accelerator laboratory could be arranged.
- Motivation letter
- Relevant certificates from the bachelor and master study
- CV with statement of the possible starting date
- Names and contact details of at least two reference persons.
Only a submission in pdf-format is accepted. As a first step, video interviews will be conducted. GSI aims to increase the number of women in scientific positions; female candidates are therefore particularly encouraged to apply. The application deadline is 30th of April 2020.
In case of any questions, please also do not hesitate to contact us.
We are looking for a skilled, motivated candidate with a university degree (Master of Science or equivalent) in physics or electrical engineering, who is expected to combine practical experimental work with exploration of basic accelerator physics by state-of-the-art simulations.
The experimental work is related to sensor technology using particle detectors and modern data acquisition systems. Programming skills for the online evaluation and the offline analysis is required. Simulations and its interpretation in terms of accelerator physics will be performed.
Besides a good eye for physical correlations and basic experience in some of the above mentioned fields, a positive working attitude, strong determination and persistency are indispensable requirements for the PhD position. Since the work will be executed within an international network with other laboratories like CERN and medical facilities at Heidelberg and Marburg, open-mindedness and social competence will be considered in the evaluation of applications.
The candidate will be employed at Goethe University Frankfurt (www.uni-frankfurt.de) and will be part of the Helmholtz Graduate School (www.hgs-hire.de). Lectures in accelerator physics and related disciplines are offered by this school as well as soft skill courses. A registration to this school is required as the final step of the recruitment procedure.
