Bachelorthesis: Two-channel optical pyrometry of ion-heated matter
Two-channel optical pyrometry of ion-heated matter
The interaction of intense ion beams with solid targets can result in significant heating of the target up to thousands of Kelvins. Recently, an ion-heating experiment has been conducted at the Gesellschaft für Schwerionenforschung (GSI) during which a two-channel optical pyrometer has been implemented for space-resolved temperature measurements (see Fig. 1 for exemplary data).
This bachelorthesis is about the analysis of the pyrometry data taken during the experiment with the goal to quantitatively infer temperature values. The analysis should include the processing of the CCD camera images and an experimental calibration of the pyrometer setup. Moreover, a comparison of the calculated temperatures with simulations of the energy deposition of ions in matter using the readily available tool SRIM would be beneficial.
Starting date: From now on, preferably no later than August 1, 2022
