Open OpportunitiesYou will optimize a model of a superconducting radio-frequency accelerator for single electrons, with the goal of achieving the best possible temporal and spatial coherence. To this aim, you will use a code that allows to track the electron through the accelerating cavity and calculate the beam parameters. Since this tracking is time-consuming, you will use surrogate modeling and optimization algorithms. You will work with a diverse team of scientists, engineers and technicians in the electron beam instrumentation group. - Engineering and Technology, Information, Computing and Communication Sciences, Physics

| In the context of the SLS-2 project, an upgrade of the existing pre-injector linac is
planned. An important aspect of this upgrade is the design of a new low RF cavity
that would greatly simplify both the layout of the linac itself and the network of
waveguide components. Basically, the RF design will be performed with
electromagnetic codes based on the finite element method using optimization
procedures. In addition, the candidate will also study the longitudinal beam dynamics
of the linac to verify that the new cavity can maintain beam quality. - Engineering and Technology, Physics

| In the frame of the SLS 2.0 upgrade project we need to design and build a couple of new beam injection elements including the Thin and the Tick septum. These are pulsed electromagnetic devices designed to deflect the electrons for short periods of time in order to utilize efficient electron injection.
After their design we need to confirm (measure) their magnetic properties to make sure they provide the necessary magnetic fields. For this we need a motorized 3-axis mover system to position a magnetic sensor and measure the field in this particular point in space. Moving to a new point and repeating the measurement we can create the respective field profiles, as well called field maps along straight lines (1D), planes (2D) or volumes (3D). In order to do this one needs to control a 3-axis mover that carries the magnetic sensor (XYZ position of the sensor) in a controlled manner (in some cases a constant speed might be necessary) and then to record the measured field values. After such measurement is done, the data (the measured field in the particular area) should be reasonably visualized.
The required tasks:
• The XYZ mover should be programed to scan predefined areas point-by-point or in certain cases line-by-line (with defined speed) communicating to a Beckhof PLC controller using a programming language and corresponding SW libraries e.g. pyadsmotion-library with Python
• For each point a measured value should be acquired from an oscilloscope and processed/recorded
• Simple intermediate mathematical processing might be necessary like numerical integration, averaging, normalization etc.
• A result file should be recorded containing the measured value for each XYZ position and possibly some description of the particular measurement
• A suitable (simple) visualization tool should be developed in order to display the measured results
• The work should be concluded with a written system description and a basic user manual - Engineering and Technology

| To achieve net zero emission targets replacement of fossil fuels is inevitable. In grand scheme of things Hydrogen plays a grand role in taking a major part of new fuel economy [1]. Techno economic analysis of hydrogen energy systems presents a very bright outlook [2]. The energy transport cost will also play an important role for the ultimate energy pricing. Therefore, it becomes imperative to search for the optimal installation locations for the large/small scale hydrogen storage systems considering the environmental, geological and accidental risk factors. A Multi criteria decision making analysis coupled with GIS data would provide the most economical and safe installation sites [3]. |
