The Institute for Beam Physics and Technology (IBPT) develops and operates the test facility FLUTE (Ferninfrarot Linac- Und Test Experiment) at the Karlsruhe Institute of Technology (KIT) based in Germany. The test facility is part of the KIT Accelerator Technology Platform (ATP). The core accelerator consists of an fs chirped laser-driven photo-injector, a linear accelerator (linac) and an electron bunch compressor to provide ultra-short electron bunches. FLUTE provides an infrastructure for ps and fs electron and photon beam studies to enable innovative technology solutions such as advanced beam diagnostics, synchronization and stabilization schemes, and to create intense terahertz (THz) radiation.

Features and equipment:

  • R&D test facility and modular accelerator
  • Photo-injector with fs/ps near-IR and UV laser system in cleanroom
  • Electron energies of 7 MeV and 40 to 50 MeV
  • Wide bunch length range from 300 fs down to 1 fs
  • Wide charge range from 1 pC up to 3 nC per bunch
  • Spectral band coverage up to 30 THz
  • THz E-field strength up to 1 GV/m

Access to KIT-based accelerators via KIT ATP is augmented by European transnational access via ARIES (Accelerator Research and Innovation for European Science and Society) for accelerator researchers and via CALIPSOplus for small and medium-sized enterprises (SME), and by European technology infrastructures such as AMICI (Accelerator and Magnetic Infrastructure for Cooperation and Innovation). Within ARIES access to FLUTE will be provided for 8 periods of 5 days per experiment (totalling 320 hours). While the FLUTE facility is in development, interested AMICI parties are encouraged to contact the Coordinator at KIT before beginning the formal application process with brief details of the test campaign proposal to discuss the experiment's feasibility.
