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!
