  10. SPARX general parameter list

  11. 3.5GeV (Xband)

  12. 12.4 1.24 0.124 l (nm) SASE RADIATION SPARX

  13. Flexible design SASE & Seeded configurations • Seed source to improve coherence length with respect to SASE • Extended use of higher order harmonics • Short pulses (fs range) • Extendable operation range to the sub-nm wavelengths (0.5 nm)

  14. Linac 150 MeV RF gun IV BC1 SPARX layout Laser heater Linac 350 MeV RFD IV Linac 500 MeV BC2 DL1 Linac 1.2 GeV IV undulators @ 1.2 GeV DL1 Linac 2.4 GeV DL2 undulators @ 2.4 GeV

  15. 1.2 GeV  10 – 6 nm 10 nm 6 nm

  16. 2.4 GeV  6 – 1 nm 1.9 nm 1.1 nm

  17. Seed Source U - 1 U - 2 e - beam λres λres/n SEEDING & Harmonic Gen.

  18. 2.6 nm Spectrum

  19. How to go to shorter wavelengths? Example: 0.5 nm Use 3rd harmonics Increase the beam Energy @ 3.5 GeV 3) Shorter period undulator 1.5 cm @ 2.4 GeV Waveguide X-band undulator @ 2.4 GeV

  20. RF Option for shorter : RF traveling wave undulator (TWU) • High power (400 MW) X-band 11.4 GHz RF source • SLAC SLED’ed system • Many novel aspects, advantages • Short u (1.5 mm) • Large aperture (low wakes) • Helical polarization (K=0.8) • Period-to-period field balance easy • Inexpensive access to sub-nm r • Experimental test in 2008 RF TW undulator: beam counterpropagating in high power RF waveguide Preliminary design for UCLA-INFN TWU experiment at BNL ATF

  21. Towards the femtosecond frontier: Extreme-low charge operation • Extreme-low Q operation • 1 nC —> 1 pC • Very low n=0.06 mm-mrad • Ultra-short beam, high I • Velocity bunching at source • Chicane bunching at 1 GeV • 1 femtosecond rms bunch • Advantages • Wakes mitigated (CSR, undulator) • Higher brightness beam (short Lg) • Single spike X-ray FEL, more stable • Time-scale of interest for probing electronic motion • Idea applicable to SPARX, LCLS Simulation of SPARX e-beam current pulse
