IPR-day with ZARM

Today we had two special visitors from ZARM (Center of Applied Space Technology and Microgravity) in Bremen – Dr. Merle Cornelius and Florian Leu – since it was time for our IPR (Integrational Progress Review).

Once they arrived, we quickly introduced ourselves and then headed straight to the lab. Since the ground station is finally set-up to communicate with SETH and receive data, we jumped right into a measurement with SETH – thus we demonstrated that SETH does measurements autonomously and automatic.

After that, it was time for our presentation. We talked about time management, gave a quick recap on mechanics and electronics, shared some updates on the software, and walked through our verification tests. And also: it was the debut of our outreach team (YAY!).

Next, we got some helpful feedback on our SED and discussed a few changes. Then we went back to the lab to take a closer look at the experiment (and took the photo above!). Since we had our guests with us, we also showed off our 3D printer – doing its printing – which was cool because several of our components are 3D-printed.

To wrap things up, we disassembled SETH as planned anyway. We’ve had a bit of noise in the data, so it needs fixing – nothing too dramatic, but still important.

After a full day at the University in Kiel, we said goodbye to our guests and are now looking ahead to the EAR in Bremen this September.
(But first… we have to make it through exam period. Wish us luck!)

Congrats, Nicolas!!!

We’re excited to announce that Nicolas, our team lead, has officially submitted his Bachelor’s thesis titled “Implementation of the Attitude Determination System (ADS) of the Scintillation Event Triggering Hodoscope (SETH).”

His work on the ADS will play a crucial role in advancing the SETH project. Congratulations from the whole team, Nicolas — we’re proud of your dedication and hard work!

Frog’s First Fitting

After the CDR, we decided to revise the design of the photodiode holder so that it could be 3D-printed as a single piece. This change simplified the assembly process and improved the structural integrity.

We completed the first assembly and fit check of the sensor head – a big milestone for the team! The 3D-printed parts fit together nicely overall. May we present the SETH frog 🐸

However, we did have to slightly enlarge the holes on the “front feet” to make it work properly.

Next up: we’ll need to reopen the shells (the silver parts that hold our crystals) to solder the coaxial cables to the photodiodes, which are glued onto the BGO crytals. Step by step, it’s all coming together!
