  1. Status of ANKA E.Huttel, I.Birkel, A.S.Müller, P.Wesolowski, N.Smale Status New Beamlines Insertions New e-gun PVSS Bunch by bunch T-Bone-Project

  2. New Beamlines CD 2009 On the way from SRS IMAGE In Planning CD In operation: 13 In construction: 3 In Planning: 1 NANO In construction In operation 2010 IR II In Construction In Operation 2009

  3. Construction Work NANO WERA NANO FELIG

  4. 10 mm NEG coated Al chamber for the SUL Wiggler Reduced Injection Rate I inj.: 180 mA vert. β: 7 m Enhanced Radiation still uncritical 16 mm (ACCEL) 14 mm (ANKA)

  5. New Insertion Device SCU15 In behalf of the insertion device group New contractor: Babcock Noell Delivery: Mid 2009 Period Length: 15 mm Magnet Gap: 8.5 mm Vacuum Gap: 7 mm Field: 0.8 T

  6. New Single Bunch e-Gun Financed by HGF Special research Fond Object: Single Bunch operation Concept: Replace diode e-gun by standard linac triode e-gun Offer from Thales and ACCEL Specification: Single Bunch Charge: 2 pC Peak Width (FWHM): 1 ns Long Bunch current: 0.2 A Gun Voltage: 90 kV Norm.Emittance (2 σ): 20 µm Repetition Rate: 1 Hz

  7. Space Charge in Gun to Linac Initial specification 1 A single bunch current Small solenoids do not compensate space charge E-gun calculation give limit of 0.4 A 10 mm diameter 14 mm diameter

  8. Gun Test Gun at PPT for cathode conditioning Acceptance test week 49 Emittance Measurement by Pepper-Pot Installation Jan.2009 0.5 A single bunch 0.2 A long pulse mode

  9. The Old Gun (10 Y) Leak at glued feed through Exchanged cathode Leak at brazed water to vacuum connection Now pump cooling tube Weld from outside Glued feed through O-Ring sealing Brazed water to vacuum connection

  10. LIBERA Bunch by Bunch Feedback Used for analysis Loop not yet closed Wait for single bunch operation 3 ‘trains’ filled with ~32 bunches

  11. Vertical Instabilities turn by turn fft turn by turn fft bunch position 2.5 GeV: longitudinal stable, vertical unstable, vertical tune, mode ~90 0.5 GeV: longitudinal and vertical unstable, synchrotron tune, no vertical tune!? Vertical instability not multi bunch How to fight?

  12. New PLC for Klystron control : PVSS Process Visualization Supervising System Developed by ETM (Austria) Siemens group Evaluated for CERN Experiments Connected to Siemens S7 PLC (replacing Bosch PLC) Control and Monitoring of PLC Data Visualization of Data Archiving of Data Alarm handling Platform Independent Already Integrated: Beam Line-Vacuum, Civil-Engineering Next Steps: Integration of Storagering-Vacuum, Timing,…

  13. Beyond ANKA: TBONE On behalf of A.S. Müller TBONE THz Beam Optics New Experiments

  14. TBONE Parameter Charge: 0.1 nC Repetition Rate: 10 MHz Average Current. 1 mA Pulse Width: 5 ps Emittance (nor.): 2 µrad Gun: DC+Buncher (5 MV) or SC-RF Acceleration: 3 SC TESLA 18 cell Cavities 15 MV/m Beam-Transport: Bunch Compression (Magnetic Chicane + Chromatic Arc)

  15. TBONE Bunch Compression

  16. TBONE - A THz/Mid-IR InstallationA Future User Facility at ANKA 5 fs pulses frequency range: 0.1 to 150 THz peak power in the MW range repetition rate of 10 MHz leads to average power in the W range covers the gap in today’s high power broadband sources in the THz / mid-IR

  17. Further Plans For ANKA : Full Energy Injector + Modified Storage-Ring Full Energy Injector like SLS, ALBA Storagering: New Dipole with gradient Shifted Quadrupoles Gain Space for larger Injection Elements

  18. Modified Storage Ring Optics (SPEAR like) Emittance: 50 nm Tune h/v: 6.8 / 2.7 New Dipoles with gradient k=-0.2 Shift of Quadrupoles Additional small Quadrupoles Emittance: 35 nm Tune: 7.2 / 2.7

  19. Full Energy Injector Circumference: 94.8 m Emittance: 40 nm Defocusing Bend: r: 7 m k: -0.6 Focusing Bend: r: 16 m k: 0.8

  20. Thank You For Your Attention
