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
