Trainee (index no. 8416-T1)

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
