Prof. Judith Golda from RUB and Prof. Claire Douat from GREMI in Orléans have arranged several exchange visits between the groups with measurement cam- paigns in the respective laboratories within the frame- work of a DAAD exchange program (part of a PROCOPE project) and have already partially carried them out. The focus of the exchange is on the investigation of the role of CO in the treatment of biological substrates.

At the end of April, the French delegation consisting of Prof. Claire Douat, Eloise Mestre and Dr. Inna Orel was again in Bochum to measure rotational temperatures on the kHz-jet from Orléans. Here, with the support of Dr. Laura Chauvet as well as Daniel Henze in the labora- tory of Prof. Judith Golda, experimental results could again be obtained. In the end, several successful meas- urement campaigns were carried out over the last few visits. Therefore, the revisit was used to lay the foundation for a cooperative publication of the two groups, which will be submitted soon. Finally, Eloïse Mestre presented their results at the ISPC 25 conference in Kyoto, Japan.
