Beschreibung
One of the goals of the laser ion acceleration research at Helmholtz-Zentrum Dresden – Rossendorf, Germany, is to develop a reliable accelerator system based on a cryogenic jet target. To ensure a high reliability, these jets must have a high position stability. Therefore, the position fluctuations of such a cryogenic cylindrical hydrogen target are investigated. For this purpose, an evaluation algorithm for position determination is developed. It is capable of reliably and quickly evaluating the position of the jet from images from different diagnostics. With the help of this automated evaluation, the dependence of the position stability on the distance to the source was investigated. In addition, the impact of a mechanical separation system on the position stability was investigated for the first time. The presented work marks the first step towards an automated and stable operation of a cryogenic hydrogen target at high repletion rates.
