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