Summary "R & D Plans 1"

1. Summary "R & D Plans 1" Patric Muggli Max Planck Institute for Physics, Munich • Plans for development of facilities with schedule • 5 year perspective (level of approved support: funded/proposed/idea) • Motivation and objectives • Acceleration goals (summary table) • Application goals • Possibilities for open access • Expectations for network Disclaimer 1: all slides with nice graphics and useful information shamelessly stolen from original talks Disclaimer 2: everything else is the opinion of the convener Disclaimer 3: convener may change his mind at any time without notice Disclaimer 4: I have 30min. I need to simplify! Sorry!

3. Four “drivers” for photon sources • Storage rings • Linacs • Energy Recovery Linacs (ERLs) • Plasma-based (LWFA, betatron)

4. >50 storage ring-based photon sources In the context of this workshop: • Storage rings cannot operate at short, x-ray wavelengths, produce short pulses, because: • Too high an emittance • Flat, unequal emittances beams • Too long for short, coherent photon pulses • Low peak current

5. Too high an emittance • Favors • Many dipole magnets • Small dynamic aperture • Large rings • pm-rad difficult but possible

6. Flat, unequal emittances beams • Use undulator insertion device for emittance transformation that preserves exey <ex+ey (ex>ey) to get round beam • Too long for short photon pulse

7. Linacs: • Great LCLS success • Mushrooming everywhere • Possibility of operating at higher charge for larger photon flux • Quest for single spike coherent pulse: • Seeding with high harmonic of a laser • Echo, successful experiments @ SLAC • Operation at very low charge (<1pC?)

8. Parameters between storage rings and linacs: large average current (SR) and short bunches (linac) Challenge: injector for CW operation, SC system.

9. Challenges and possible progress with all photon source drivers, including plasma-based ones!

10. France Many (collaborating) institutions

11. All (geographically) close to each other

12. Number of institutions, “satellite”, laser systems (ILE, LAL, LCFIO, LLR, LOA, LPGP, LULI, LUMAT, CPhT, IRAMIS, IRFU, CEA – Saclay, SOLEIL) ➤ LOA «Salle Jaune» ~2x60TW after upgrade ➤ CEA/IRAMIS «UHI100» up to 100TW ➤ LASERIX (2J, 40fs), dedicated for X-ray laser facility, also LUIRE pump laser New kids on the block …

13. Very large experimental area!

14. France

16. Elements of a plasma based collider: Conventional + Plasma Plasma + Plasma

17. HEP orientation with quality beams at two main facilities Other physics/applications at satellite facilities

18. Italy Program for RF-gun beam injection in LWFA, TS scattering, PWF with bunch train

19. Aim at: 250TW, 25fs, 10Hz Preliminary LWFA results

21. 24/7?

22. Italy

23. Main objectives: -injection of photo-injector bunch in FLAME-driven LWFA -Thomson scattering

25. Good bunch quality can be produced, preserved emittance

27. Italy PWFA oriented

28. Drive laser manipulation and velocity bunching, emittance compensation for bunch current manipulation

29. Facility in existence

30. Echo-like experiment Train of bunches for large transformer ratio experiments, i.e., large energy gain 5GV/m, 3 bunches, 100pC/bunch, lp=300µm (ne≈1016cm-3)

31. Bunch, not particle acceleration!

32. FEL applications of multi-bunch trains?

33. International Germany (of electrons!!!!!!)

34. Motivation: a single LHC p+ bunch has enough energy (Joules) to produce a TeV, ILC-like electron bunch in a single PWFA!

35. No short p+ bunches => rely on self modulation! Measure bunch modulation, injected low energy e- gain energy 10m, Epeak~1GV/m

36. LoI to be submitted to CERN in June Experiment in 2015? Launch program for 50-1000GeV electron bunches from a single PPA!

40. Encouraging initial results

41. Strong simulation support

45. Trends: Larger lasers: 100TW -> 1PW -> 10PW -> higher energy Higher rep. rates: 1/min. -> 1Hz-> 10Hz More (laser, particle) beam lines More injection (“all optical” or from rf-sources) More diverse experiments: few LWFA (HEP), more photons (b-tron, FEL, Compton), more p+ source, more PWFA -> more applications in the longer term Longer plasmas -> guiding More stability More reproducibility Desire for more dedicated facilities needed to make rapid progress toward LWFA-FEL and PLIC (plasma-based linear collider)? • Plans for development of facilities with schedule • 5 year perspective (level of approved support: funded/proposed/idea) • Motivation and objectives • Acceleration goals (summary table) • Application goals • Possibilities for open access • Expectations for network (I suggest to circulate a empty table to fill to gather all requested parameters) Thank you to all speakers!
