Last open positions in the OMA Project!
There are two ESR positions available in the OMA Project: at Paul-Scherrer Institute in Switzerland and at Vialux, a private company in Germany.
The project at PSI RF-based Measurement of Ultra Low charges will focus on improvements or development of new diagnostic systems that play an important role to optimize medical treatment schemes. Currently, ionization chambers are the most commonly used detector type for beam intensity measurement. However, they use thin foils which are crossed by the beam and decrease the beam’s quality by scattering. To mitigate this problem a Fellow shall develop a sensitive RF-based current monitor for fully non-interceptive beam current measurement and shall study the possibilities to measure the beam position. The system improvements will target measurement of beam currents at a very low beam intensity. The design will be based on previous developments at PSI and will also take into account developments at other OMA institutions.
Within the project at Vialux a Fellow will work on development of New encoding methodologies for ultra-fast 3D surface scanning. They will combine a time sequence of binary patterns with partial dithering in each of these bit plane patterns in the sequence. Furthermore, a Fellow will design and analyze methodologies of fringe pattern generation that work with a minimum of bit planes and provide the maximum precision for 3D-scanning to achieve ultra-high scanning speeds, maintaining the typical quality of phase shifting measurements. Both, theoretical and experimental work will be performed, starting from the basic pattern generator up to the full evaluation of 3D scan result in a corresponding laboratory setup and comparison with alternative techniques studied within OMA.
