Study of HCAL mechanics -- by Yong Liu

P5: Why performance is bad in low momutum

The angle of two modules of layout 2 may affect reconstruction simulation

 

Why cannot large area PCB? Now is 3 pieces of 72*72, total 72*240.

--> Manufacturing problem.

 

P9: did you consider error bar of two distribution? Prepare the answer for this question which may be asked at CEPC Day.

 

Cost: Make a table for comparison that Yifang wanted.

 

Review of the fast scintillating material workshop -- by Sen Qian

Q: how you get requirement for light yield?

From simulation, with >1000 ph/MeV light yield, we can get about 3% resolution

15:00 → 15:20 Experience of CEPCSW on the tracker optimization

Speaker: Xin Shi (IHEP)
