Today's focus:
[STCF EMC]:- The crystal optical simulation was updated by moving the particle source to 1 m away from the crystal detector, making it more consistent with the actual collider environment. Under this setup, the time distributions of different particle types are more clearly distinguishable. The reason is that particles with different masses have different flight velocities, which means particle identification via timing information is more promising.
- From left to right: 1GeV - 100MeV - 10MeV
- Collect some cosmic-ray events that incident along the crystal’s length direction. The timing resolution is about 0.46 ns, and after removing the contribution from the trigger detector, it is about 0.32 ns.
[DarkSHINE ECAL Prototype]:
- I studied the flex cable design used in the CMS MTD BTL detector and am currently making a PCB prototype to verify the feasibility of applying a flex cable connection in the DarkSHINE ECAL prototype. The plan is to submit it to the factory for production before the festival.
Plans:
- [STCF EMC] : Plan to explore series/parallel readout schemes for multiple SiPMs to improve timing resolution while also preserving energy-signal measurement performance. This will also require designing dedicated readout electroncis.
- [DarkSHINE ECAL prototype] : Completed the flex cable design and tested the signal-quality difference compared with a standard coaxial cable connection.
