Linac for an Ultrafast Pulse Radiolysis Facility
These are parameters of an Ultrafast Pulse Radiolysis (UPR) facility.
• Maximum Beam Energy: 50 ~ 100 MeV for better beam quality & shorter bunch length
• Single Bunch Charge < 1 nC (?)
• Bunch Length ~ 100 fs (rms)
• Normalized Emittance < 2 ㎛
• Operation Mode: Pulsed Mode
• Repetition Rate: 60 Hz
• Layout: S-band Gun + Gun Solenoid + 3 m Linac + X-band Cavity
  + Quadrupoles + Chicane Bunch Compressor + Quadrupoles + 3 m Linac
  + Quadrupoles + TDS + Quadrupoles + Dipole + User Beamlines
  + Beam Dump
• Required Chiller: 150 kW / 50 ton
• Shielding: 9" (?) floor and wall (300 kg structure, 13000 lbs RF system)
• Tunnel Length for Linac: about 25 m (user beamline is not included here.)
• AC power line with 600 A (?), 208 V 3 phases
