Mechanical Engineering Center’s Masterpiece: 3D model of “Belle II detector”

KEK Spring Campus Open House was held on April 20 during “Science and Technology Week 2024.”
In the Science Cafe “CV of Doctors” (Fig. 1), a 3D model of Belle II detector (Fig. 2) was placed near the moderator, which was manufactured by the Mechanical Engineering Center using a 3D printer at the request of the Institute for Particle and Nuclear Studies.
The Belle II detector is placed at the collision point of the SuperKEKB accelerator and consists of various detectors.
The model can be disassembled to understand how it works, and a FDM (Fused Deposition Modeling) type 3D printer was used, which can use materials in a variety of colors.
The detectors are attached to each other with magnets.
It will be exhibited at the KEK booth of the Niconico Chokaigi 2024.
