Compact Photon Source (CPS) Design
Chong Shik Park
Indiana University and IUCF
Layout of CPS
• Total circumference: 17.6 m• Electron beam energy: 25 MeV• 4 Bending Dipoles• 2 Wigglers with gradient• Momentum Compaction Factor can be tunable by
changing the gradient and magnetic field of wiggler dipoles
Length of the Bending Dipoles I
Length of the Bending Dipoles II
Edge Angle of the Bending Dipole I
Edge Angle of the Bending Dipole II
Gradient of the Wiggler Dipole
• Use the wiggler dipoles with gradient to tune the damping parameters
• Change the B1/B0 of Bz
