## Details

### CEPC_v4
 - BeamPipe
         - Z from 0 to 700mm same as MokkaC's CEPC_v4
 - Vertex
         - with silicon ladders (VXD + SIT)
 - MainTracker
         - TPC
         - TPC_outer_radius = 1808*mm
 - EndcapTracker
         - with silicon pestals (FTDPixel + FTDStrip)
 - Ecal
         - with si-W calorimeter
 - Hcal
         - with RPC readout
         - creates three sets of hit collections
 - compact files:
         - only Tracker [./CEPC_v4.xml](./CEPC_v4.xml)
