  1. DR 3.238km DTC02 Lattice 23 September 2011

  2. DTC02 layout • Circumference = 3238.681m • Harmonic number =7022 • 710m straights • ~ 6 phase trombone cells • 60– 2.1m long wigglers • wiggler period = 30cm • 14-poles • Bmax = 2.16T • 4. Space for 16 RF cavities • Cryostats for upper and lower positron rings • are interleaved

  3. Arc cell - FDBDF Cell length = 10.93m Bend length = 3.0m 75 cells/arc

  4. DTC02 lattice functions

  5. RF cells

  6. Extraction straight

  7. Injection straight

  8. Circumference changing chicane

  10. DTC02

  11. RF The lattice can accommodate 16 RF cavities If we assume 12 then Voltage/ cavity in 10Hz mode is 1.64 Power/coupler in 5Hz, high power mode is 300kW

  12. Dynamic aperture5 Hz Periodic type wiggler model, includes vertical focusing and cubic nonlinearity

  13. Dynamic aperture10 Hz Periodic type wiggler model, includes vertical focusing and cubic nonlinearity

  14. Magnet count (storage ring)

  15. Injection/Extraction Positrons – injection from left, extraction to right Electrons – injection from right, extraction to left Midpoint between injection and extraction kickers is 2.56m from center of straight Angle at entrance/exit of transfer lines with respect to storage ring straight = 240mrad

  16. Injection/Extraction (Injection and extraction lines are identical) Angle with respect to storage ring straight = 240mrad
