CHAOS has successfully started into the year 2024. The next big milestone on our journey is the Preliminary Design Review (PDR) in Kiruna, Sweden at the beginning of February. At the PDR we will present the current status of our experiment design. But first, we have to hand in our first version of the SED (Students Experiment Documentation) at the end of January. This document includes all relevant information regarding our experiment. Currently, we are finalizing the design of CHAOS to include it in the SED and present it at the PDR. It is a lot of work but also a lot of fun. We have been told that it might be cold in Kiruna, but the polar lights make up for it. Therefore, the work will be definitely worth it. Stay tuned for more information on CHAOS and our journey to Sweden.
